Every acre a T100 or T70P treats gets its coverage from one spinning part: the centrifugal spray disc. It is the last thing the chemical touches before it becomes mist — and the quality of that mist decides whether the operator gets even coverage or streaks, drift, and wasted product.

Spray discs are true consumables. They spin at brutal speeds in a bath of abrasive chemical, and as the teeth wear, atomization degrades quietly — droplets get coarser, patterns get uneven, and the aircraft burns the same battery and chemical for worse results.

That is why Ares Acres keeps hard-to-find spray system components in stock and shipped fast to the U.S.A., helping operators restore sharp atomization, minimize downtime, and keep their aircraft spraying at full effectiveness when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators, fresh spray discs are the cheapest coverage upgrade there is.

🔧 Component Overview

The DJI Agras T100 - T70P Replacement Double-Layer Centrifugal Spray Disc is a precision aftermarket atomization disc designed for the centrifugal spray nozzles of the DJI Agras T100, T70, and T70P agricultural drones.

This is a double-layer, dual-turbo integrated spray plate: a fine-toothed upper ring (supplier-stated 270 teeth) working over a coarser lower ring (75 teeth), built in high-strength nylon with a vortex-growth profile the supplier reports delivers more uniform atomization and finer droplet formation than a worn standard disc. Multiple simulation and timing tests are cited by the manufacturer behind the design.

The disc mounts directly to the centrifugal nozzle assembly and goes straight to work turning liquid into the fine, even mist that commercial application depends on.

Commercial agricultural drones operate in demanding environments every day, including:

• Crop spraying
• Liquid fertilizer application
• Herbicide treatments
• Fungicide applications
• Insecticide spraying
• Orchard operations
• Vineyard spraying
• Specialty crop programs
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, spray discs are routinely exposed to:

• High-RPM centrifugal loading every second of spraying
• Abrasive chemical formulations
• Fertilizer particle wear
• Chemical corrosion attack
• Grit and debris in the liquid path
• Pressure-washing and rinse cycles
• UV exposure
• Heat cycling in summer conditions
• Transport vibration
• Long commercial operating hours

Over time, this wear dulls and erodes disc teeth — and worn teeth mean coarser droplets, uneven patterns, and coverage quality the operator can't see degrading until the results show it.

The Replacement Double-Layer Centrifugal Spray Disc helps restore:

• Fine, uniform droplet atomization
• Consistent spray pattern quality
• Even chemical coverage across the swath
• Full centrifugal nozzle performance
• Efficient chemical utilization
• Reduced drift from oversized droplets
• Sharp application quality on every pass
• Consistent maintenance standards
• Increased fleet readiness
• Maximum aircraft effectiveness
• Reliable commercial operation

For operators whose results are judged acre by acre, fresh discs are where application quality starts.

Keep one new disc sealed in the box as a reference sample, because tooth wear is almost impossible to judge in isolation. Put the suspect disc next to the new one under the same light and look along the tooth tips at a low angle: sharp edges stay dark, while rounded ones catch the light and glint. Then drag a fingernail across the crests of each in turn. A fresh tooth catches the nail and a worn one lets it slide. That side-by-side takes ten seconds and settles an argument that guessing never will.

Separate an atomization problem from a flow problem before you order discs. Thin coverage has two completely different causes: droplets that are too coarse to deposit, or simply not enough liquid arriving at the head. Check the delivered flow first, by whatever method your system gives you, and confirm the aircraft is actually putting out the rate it says it is. If the flow is correct and the coverage is still poor, the fault is in how the liquid is being broken up, and that is the disc.

Prove it with water-sensitive paper rather than with your eyes at the truck. Lay cards across the swath, run a pass with clean water at your normal speed and rate, and read the stain pattern: a healthy disc gives you a dense, even scatter of small stains, and a worn one gives fewer, larger, more clustered marks with bare paper between them. Run the same test again after fitting fresh discs and keep the cards. Two sets of cards from the same aircraft are worth more than any droplet figure printed on a package.

Find out whether it is one head or all of them before you condemn the set. Run the system with clean water on the ground with the aircraft secured, and watch the discharge from each nozzle in turn from a safe distance and angle. A good head throws an even curtain all the way around. A worn or damaged one throws visible fingers, streaks, or fat droplets that break out of the ring on one side. If only one position is doing that, look at that disc and that head, not at the whole aircraft.

⚙️ Functional Purpose

The Replacement Double-Layer Centrifugal Spray Disc is designed to restore and sharpen the atomization performance of T100 / T70 / T70P centrifugal spray nozzles.

The component helps:

• Atomize liquid into fine, uniform droplets
• Drive atomization through its dual-turbo tooth rings
• Deliver the supplier-reported vortex atomization profile
• Maintain even swath coverage
• Support consistent droplet sizing
• Reduce coarse-droplet waste and runoff
• Replace worn, chipped, or eroded discs
• Restore full nozzle output quality
• Mount directly to the centrifugal nozzle assembly
• Maintain correct fitment on the spray system
• Support preventative maintenance
• Reduce preventable coverage failures
• Reduce preventable downtime
• Increase fleet readiness
• Keep spare-parts inventory field-ready

Application quality lives and dies at the disc — it is the final part the chemical touches before the crop.

A fresh disc keeps droplets fine, patterns even, and every tank of product working as hard as the operator does.

A worn or damaged spray disc may contribute to:

• Coarse, inconsistent droplets
• Streaked or uneven coverage
• Wasted chemical and poor efficacy
• Increased drift risk
• Re-treatment costs
• Interrupted spraying missions
• Unexpected downtime
• Higher operating costs over time
• Reduced fleet reliability

Replacing worn discs helps restore the atomization quality the spray system was engineered to deliver.

Flush before you handle anything on the nozzle, then kill the power. Run clean water through the spray system so the residue on and around the disc is water rather than concentrate, and shut the aircraft down and disconnect the batteries so a nozzle motor cannot spin up while your fingers are on the rim. Wear gloves. A spray disc that has been in service is coated in dried chemistry on both faces, and the tooth edges on a fresh one are sharp enough to cut you.

Note the orientation before the disc leaves the hub. A double-layer plate is not symmetrical, and it will physically sit on the hub the wrong way up while looking almost right, which gives you a disc that spins but atomizes nothing like it should. Photograph it in place from the side, or mark the upper face with a wrap of tape before you release it, and set it down on the bench the same way up. Then lay the new disc beside it and confirm the two agree on which ring faces out.

Release the retainer without fighting it and without gripping the rim. Work out which way the retainer frees before you lean on it, since fasteners on a rotating assembly are often threaded to resist the direction of rotation and guessing wrong rounds the flats off in one pull. Counter-hold the hub the way the design intends rather than clamping the toothed edge in pliers, because crushed teeth on a disc you were only inspecting turns a maybe into a definite replacement.

Clean the hub face before the new disc touches it. Dried mix, grit, or a shred of old sealant trapped between disc and hub holds one side of the plate up by a fraction, and a plate that sits even slightly out of true at spray RPM throws an uneven curtain and loads the nozzle motor bearing for the rest of its life. Wipe the seat and the spigot clean and dry, check the hub itself for scoring or a wallowed drive feature, and only then fit the disc.

Verify the fit before you put chemical through it. Seat the disc flat, tighten the retainer to the value your service documentation gives rather than to feel, then spin the head slowly by hand while sighting the rim against a fixed reference such as a screwdriver held near it. The gap should not open and close as it turns. Finish with clean water through the system and watch the discharge ring from each head, then run one short loaded pass and check for weeping or wobble before committing to the field.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Worn, rounded, or eroded disc teeth
• Chipped or broken teeth
• Visibly coarser spray droplets
• Uneven or streaky spray patterns
• Reduced swath uniformity
• Chemical-related surface deterioration
• Cracks in the disc body
• Disc wobble or imbalance vibration
• Scoring from grit and debris
• Maintenance inspection findings
• Seasonal spray system rebuilds
• Fleet refurbishment projects
• Preventative pre-season replacement
• Long-term commercial wear

Common causes of disc wear include abrasive chemical formulations grinding at high RPM, fertilizer particles eroding tooth edges, chemical corrosion softening surfaces, grit riding through the liquid path, and plain accumulated hours — spray discs are consumables by design, and sharp fleets replace them on schedule rather than waiting for coverage complaints.

For commercial operators, preventative disc replacement is almost always cheaper than the re-treatment an uneven application forces.

Streaking that repeats in the same place across every pass, at a spacing that matches your nozzle positions: that is one head, not the whole spray system. A rate error or a pump problem thins the entire swath evenly, while a worn or chipped disc leaves its signature in a fixed strip. Note which side of the aircraft the streak falls on, then go and compare that head's disc against the others and against your reference sample.

Product visibly running off the leaf or collecting on the ground under the canopy: droplets are arriving too large to stay where they land. Coarse droplets bounce off waxy leaf surfaces and coalesce and run instead of sitting as discrete deposits, so the tank empties on schedule and the crop still gets less than it should. If the rate is right and the deposit is wrong, the shear happening at the tooth edge is what has changed.

A nozzle head that sounds different from its neighbors, or a whine that rises and falls as it spins up: an unbalanced plate. Uneven tooth erosion, a chip out of the rim, or a crack in the body moves the center of mass off the axis, and the head then vibrates through its own motor and mount. Treat a head that has started making a new noise as a head to inspect immediately, because the imbalance damages the nozzle motor long before it stops the aircraft.

Spitting, dripping, or fat droplets breaking out of the mist at the start and end of each pass: liquid is not being picked up and sheared evenly across the plate. That often traces back to residue built up in the tooth roots on one side of the disc, which changes how the film spreads before it reaches the tips. Flush and inspect first, since a disc that comes clean and works properly again tells you the real fault is the rinse routine rather than the part.

The same nozzle position reporting a fault or needing attention again after a previous repair: something at that head keeps destroying discs. Look past the disc at that point. A scored or wallowed hub, a bearing with play in it, a feed line delivering grit because the filter has been bypassed, or a retainer that has never been properly tightened will chew through new discs as fast as you fit them.

Coverage that has quietly gotten worse across the season with no single event to blame: this is the normal failure mode and the reason a reference disc matters. Teeth do not fail, they retreat, a little each tank. Nothing looks broken, nothing throws an alarm, and the aircraft flies exactly as it always did. The only reliable way to catch it is to compare against a new disc and against water-sensitive cards from earlier in the year.

Compatibility (Supplier-Listed Fitment):

• DJI Agras T100
• DJI Agras T70P
• DJI Agras T70

Package Quantity: 1 Disc

Installation Area: Centrifugal spray nozzle assembly

Function: Atomizes spray liquid into fine, uniform droplets

Design: Double-layer dual-turbo plate — supplier-stated 270-tooth upper ring over 75-tooth lower ring, vortex-growth profile

Construction: High-strength nylon (supplier-stated)

Mounting Type: Direct-fit replacement component

Application: Agricultural drone spray system maintenance and atomization restoration

Disc Diameter, Bore and Thickness: Not published in this listing. Compare the replacement directly against the disc you removed for outside diameter, bore, hub drive feature and overall stack height before fitting, and confirm the position on the parts diagram for your aircraft.

Droplet Size Range: No droplet spectrum figure is published here, and any number would depend on your spray RPM, mix, and rate in any case. Verify what you are actually producing with water-sensitive paper under your own conditions rather than relying on a figure from a package.

Chemical Compatibility: No compatibility chart is published for the nylon used here. Nylon takes up moisture and is attacked by some solvents and adjuvants, so if you run an unusual carrier or a strong solvent-based product, check the disc more often rather than assuming it is unaffected.

Retaining Hardware: One disc is supplied. The retainer, washers, and any hub hardware are not included, so reuse the originals only if they are undamaged, and tighten to the value in your service documentation rather than by feel.

Runout and Balance Tolerance: Not published. Use the practical check instead: spin the fitted head slowly by hand and sight the rim against a fixed reference. Visible movement at the rim is enough reason to pull it back off and find out what is holding it out of true.

When application quality is the product being sold, fresh discs on the shelf keep the promise.

Identify a double-layer disc by its stack, not by its outline. Turn the disc on edge and look at it side on: this one is two tooth rings on top of one another, a fine ring working over a coarser one, and the single-layer discs used on the smaller Agras spray systems have a single ring at that same view. The bore and hub interface differ as well, so measure both against your removed disc. From directly above, at arm's length, all of them look the same, which is exactly how the wrong one gets ordered.

Do not mix a fresh disc in among worn ones and expect an even swath. Every head on the aircraft has passed the same tanks of the same chemistry for the same hours, so they wear together, and a new disc alongside worn neighbors produces a strip of fine, dense coverage against strips of coarse, thin coverage. That is worse for uniformity than leaving all of them worn. Change them across the aircraft together and log the date and the acres so the next set has a reference.

While the disc is off, inspect the parts that share its life. Check the nozzle motor for bearing play and roughness by hand, look at the hub seat and drive feature for scoring or a wallowed edge, check the feed line and its drip point for hardening and blockage, and look at the shroud or guard for cracks and heavy build-up. A disc that arrived worn out early usually did so because something else at that head was already wrong.

Do not confuse the atomization disc with the other rotating and stationary pieces inside the same nozzle. The liquid distributor, feed cup, and any sleeve or spacer between the hub and the plate can look like part of the same assembly on the bench once everything is apart. Lay the parts out in the order they came off, keep each head's hardware separate from the others, and rebuild one head completely before you take the next one apart.

💡 Why This Part Matters

Every gallon a T100 or T70P carries was paid for twice — once at the chemical dealer, and once in flight time. The spray disc is the part that decides whether that investment lands on the crop as fine, even coverage or gets wasted as coarse droplets and streaks.

Operators watch batteries and motors, but the disc wears silently: teeth round off a little more every tank, atomization drifts coarser, and by mid-season the aircraft is quietly delivering worse coverage at the same cost per acre. The fix costs less than a single re-treatment.

The supplier engineered this disc as a double-layer, dual-turbo plate — a 270-tooth fine ring over a 75-tooth drive ring with a vortex-growth profile they report produces more uniform atomization than a standard worn disc, validated through their simulation and timing testing.

The Replacement Double-Layer Centrifugal Spray Disc helps restore:

• Fine, uniform atomization
• Even, professional coverage
• Full chemical efficacy
• Efficient product utilization
• Consistent swath quality
• Cleaner application results
• Professional fleet standards
• Increased aircraft effectiveness
• Reliable commercial performance
• Long-term operational confidence

Flying a worn disc, operators risk:

• Coarse droplets and poor efficacy
• Streaked, uneven fields
• Wasted chemical spend
• Drift complaints
• Re-treatment costs
• Unhappy contract customers
• Lost spraying reputation
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the spray. Protect the coverage. Protect the mission. Protect the season.

Professional DJI Agras operators understand that application quality is built one component at a time. Keeping fresh spray discs on hand means a five-minute swap at the truck instead of a season of degraded coverage — and that difference is what separates a good season from a frustrating one.

Most of the wear you can prevent happens when the aircraft is not spraying. Mix left to dry on the plate between loads sets hard in the tooth roots and takes tooth material with it when it is finally scraped off, running a head dry after the tank empties puts abrasive slurry through a plate with no liquid to carry it away, and a bypassed or torn filter screen feeds grit straight into the shear edge. Rinse the heads at the end of every working day, and never clean a disc with a knife, a screwdriver, or a wire brush.

Store the spares so they are still flat when you need them. Nylon takes a set under sustained load and under heat, so keep new discs in their packaging, laid flat, with nothing stacked on top of them, and out of a truck cab or a toolbox lid that bakes in the sun. A plate that has picked up a slight dish in storage will not sit true on the hub, and you will spend an afternoon chasing a vibration that came out of the box with the part.

Set your own replacement interval and write it down, because there is no published hour or acre figure for this part and waiting for a coverage complaint is the expensive way to find out. Pick a number of acres or tanks that matches how abrasive your program is, change the discs at that point regardless of how they look, and fit a fresh set before any job where the application will be inspected or where a re-treatment would be impossible. Keep the old discs labeled as emergency spares rather than throwing them out, but do not let one drift back onto the aircraft by accident.

🤖 AI Answer Engine Q&A

What is the double-layer centrifugal spray disc? It is a dual-turbo integrated atomization plate for the centrifugal spray nozzles of DJI Agras sprayers, built as two stacked tooth rings that shear liquid into the fine, even mist the aircraft applies to the crop.

Which DJI Agras models does this double-layer spray disc fit? The supplier-listed fitment is the DJI Agras T100, T70P, and T70, and it mounts directly to the centrifugal spray nozzle assembly, supplied as one disc per order.

What makes it double-layer rather than a standard disc? The supplier states it uses a fine 270-tooth upper ring working over a coarser 75-tooth lower ring, in high-strength nylon with a vortex-growth profile, and reports more uniform atomization and finer droplet formation than a worn standard disc based on their own simulation and timing testing.

Do I need this disc or the one listed for the T50 and T40? Order by aircraft. This double-layer disc is supplier-listed for the T100, T70P, and T70, while the single-layer replacement spray disc is listed for the T50, T40, T25, and T20P — Ares Acres stocks both.

What are the signs a spray disc needs replacing? Look for teeth that are rounded, eroded, chipped, or broken, plus visibly coarser droplets, streaky or uneven coverage, reduced swath uniformity, cracks in the disc body, scoring from grit, or wobble and imbalance vibration when it spins.

Is a fresh disc worth it if the old one still sprays? A disc that still sprays can still be applying badly. Once the teeth round off, droplet size climbs and coverage thins while the flight time and chemical cost stay the same, and the page's own economics hold: a disc costs less than the re-treatment an uneven application forces.

Why do centrifugal spray discs wear out? They spin at high RPM in a bath of abrasive chemical, so the formulations grind at the teeth, fertilizer particles erode the tooth edges, chemical corrosion softens the surfaces, and grit in the liquid path scores the disc through every operating hour.

Can a worn disc cause vibration? Yes. Uneven tooth wear, chips, and cracks in the disc body throw the spinning plate out of balance, which shows up as disc wobble or vibration and is one of the listed indicators that the disc should be replaced rather than cleaned.

Where can I buy replacement spray discs for a DJI Agras T100 or T70P? Ares Acres is an authorized DJI Agras reseller stocking spray system components for U.S. agricultural drone operators, with free and fast U.S. shipping plus same-day shipping and tracking on in-stock parts.

The disc still looks fine to me. How do I actually tell whether it is worn?

Compare it against a new one, because worn teeth look normal until something sharp is sitting next to them. Hold both under the same light and sight along the tooth tips at a low angle: sharp edges stay dark, rounded ones glint. Drag a fingernail across the crests of each and feel which one catches. Then back it up with water-sensitive paper on a clean-water pass, where a worn disc shows fewer, larger, more clustered stains with bare paper between them.

Should I change every disc on the aircraft or just the one that looks worst?

Change them together. All the heads have run the same chemistry for the same hours, so they are at the same point in their life whether or not they show it equally, and dropping one fresh disc in among worn ones gives you a narrow strip of fine coverage against wide strips of coarse coverage. Uniformity across the swath is the thing you are actually buying, and a mixed set works directly against it.

Can I clean a worn disc and keep using it?

Cleaning is worth doing and it fixes a real problem, but it is not the same problem. Washing dried mix out of the tooth roots restores how the liquid film spreads across the plate, and a disc that atomizes properly again afterward was dirty rather than worn. What cleaning cannot do is put back tooth material that has eroded away. If the edges are rounded against a new reference disc, no amount of soaking changes the geometry that does the shearing.

Do I need to change my rate settings after fitting fresh discs?

The rate itself is set by the liquid the system delivers, not by the disc, so your programmed rate does not change. What changes is where that liquid ends up, because finer, more uniform droplets deposit differently and penetrate the canopy differently than the coarse ones a worn disc was throwing. Run water-sensitive cards on the first job after the change and look at the deposit before you decide whether your speed and rate still suit the target.

Which way up does a double-layer disc go on the hub?

It is not symmetrical, and it will sit on the hub upside down while looking close enough to fool you, so decide before the old one comes off rather than after. Photograph the fitted disc from the side or put a wrap of tape on the upper face, then set it on the bench that way up and lay the new one next to it to confirm the two agree on which ring faces outward. If you have already lost track, compare the wear pattern: the face that met the liquid film is the one that shows it.
