🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Droplet size is the whole job. Too coarse and the chemical falls through the canopy; too fine and it drifts to the neighbour's field. The centrifugal nozzle is what holds that spec, and when the disc wears or the solenoid sticks, coverage quality degrades long before anything looks broken.

We ship the Centrifugal Spray Nozzle Set fast to the U.S.A.

We use specialized technicians to verify and dispatch the Centrifugal Spray Nozzle Set with Solenoid Valve ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM spray system parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The Centrifugal Spray Nozzle Set is the atomizing assembly that converts pumped chemical into a controlled droplet spectrum. A spinning disc flings liquid outward at a rate that determines droplet size, while the integrated solenoid valve controls flow to the nozzle on command from the flight controller.

The Centrifugal Spray Nozzle Set supports:

• Controlled, repeatable droplet size
• Accurate flow gating via the solenoid
• Even coverage across the swath
• Correct application rate per acre
• Reduced drift in wind
• Restored factory spray performance
• Direct-fit boom replacement
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Wettable powder and suspension mixes
• High-tempo fill-and-fly cycles
• Long-duration spraying campaigns
• Daily commercial deployments
• Fleet operations
• High-acreage contract work
• Back-to-back tank rotations

Throughout these operations, this is routinely exposed to:

• Abrasive chemical suspensions
• Continuous rotational wear on the disc
• Chemical residue and caking
• Vibration from the airframe
• Wash-down and rinsing cycles
• Heat and humidity in the field
• Seasonal intensive operation
• Long commercial operating hours

The Centrifugal Spray Nozzle Set helps maintain:

• Target droplet spectrum
• Even, repeatable coverage
• Accurate application rates
• Reduced chemical drift
• Clean solenoid open and close response
• Full spray system output
• Consistent results between tanks
• Predictable service intervals

It helps to think of this as two different machines sharing one housing. The atomizer is a small motor spinning a disc, and it fails mechanically: bearings, imbalance, and a worn edge. The solenoid is an electrically operated seat valve, and it fails from residue and sealing, almost never from coil wear. They produce overlapping symptoms and completely different tests, so the first move in any diagnosis is deciding which of the two you are looking at rather than treating the assembly as one black box.

Droplet formation on a centrifugal head happens at the very outer edge of the disc, where liquid leaves as ligaments that break into droplets. That means the working surface is a thin band of material a few millimeters wide, and it is the part of the assembly with the least material and the most contact with abrasive product. Wear there is invisible from a distance and obvious under a light next to a new disc, which is the single best reason to keep the old set on the bench when the new one goes on.

⚙️ Functional Purpose

The Centrifugal Spray Nozzle Set is designed to restore and maintain correct atomization and flow control on the DJI Agras T100 spray system.

The part helps:

• Restore the target droplet spectrum
• Correct uneven or streaked coverage
• Replace a worn atomizing disc
• Cure a sticking or leaking solenoid
• Return application rates to specification
• Reduce drift complaints from neighbours
• Complete a spray boom rebuild
• Recover lost spray system output
• Keep a critical assembly on the shelf
• Maintain application quality through the season

Going without may contribute to:

• Off-spec droplet size and poor efficacy
• Chemical drift onto adjacent land
• Uneven coverage and repeat passes
• Application rates drifting from target
• Wasted chemical every tank
• Unplanned downtime
• Missed spray windows
• Reduced fleet availability

The solenoid is what makes swath boundaries clean. Without a valve at the nozzle, the volume of liquid already in the boom lines keeps coming out after the flight controller commands spray off, which puts unmetered product at the headland turn and on whatever you fly over between passes. A solenoid that is slow to close, or that seeps, turns every turn at the end of a pass into an unrecorded over-application in a place the mission plan says nothing was applied.

Because droplet size on a centrifugal head is set by disc speed rather than by pressure, the system can change how much liquid it delivers without changing how that liquid breaks up. That decoupling is the whole advantage, and it is also why nozzle condition matters more here than on a pressure system. If the disc edge is worn, the aircraft has no way to compensate, because the setting it controls is speed and the thing that changed is the geometry the speed acts on.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Droplet size visibly off target
• Uneven or streaked coverage patterns
• Increased drift in normal wind conditions
• Solenoid slow to open or close
• Dripping after the boom is shut off
• Visible wear or scoring on the atomizing disc
• Chemical caking that will not clean off
• Flow rate not matching the commanded setting
• Efficacy complaints after normal application
• Scheduled spray system service reached

Centrifugal nozzles wear from the inside of the spray path outward. Abrasive suspensions erode the disc edge gradually, so droplet spectrum drifts off spec over hundreds of tanks without a single obvious failure event. Solenoids fail separately, usually from residue rather than electrical wear.

One nozzle visibly different from the others on the same boom: this is the cheapest calibrated test in aerial application and it costs nothing. Same aircraft, same tank, same pressure, same command, so any nozzle that looks thinner, coarser, or narrower than its neighbors is the odd one out by definition. Watch them together during a static water run before you spend money on droplet cards or a bench.

Spray continues or drips after the boom is commanded off, with the system still pressurized: the solenoid seat is not sealing, normally because dried product built up on the seat or a particle got trapped and nicked it. Distinguish this from normal drain-down, which is a small one-time dribble as the line empties and then stops. A leak that keeps producing liquid while pressure is up is the valve.

The disc hesitates on spin-up, wobbles, or makes a whine that rises and falls: the rotating assembly is out of balance or the bearings are going. Caked product on one side of a disc is enough to do it, and it is worth cleaning and retesting before condemning the head. An imbalance that survives cleaning is mechanical, and vibration from an unbalanced head works on its mount and its wiring as well as on itself.

Coverage streaks and drift complaints in wind you used to fly comfortably: the droplet spectrum has moved away from what your settings assume. Which direction it moved depends on exactly how the edge wore, which is why the useful action is comparing the removed disc against a new one under a light rather than trying to predict it. A polished, rounded, or chipped outer edge is off spec whatever the spectrum did.

Commanded rate not achieved across every nozzle at once: this is usually not the nozzles. When all of them come up short together, look upstream at the tank strainer, the inline filter screen, a kinked or collapsing suction hose, and the pump. A restriction that starves the whole boom gets blamed on nozzles more often than any other fault in the spray system.

📐 Specifications

Component Type: Centrifugal atomizing nozzle set with integrated solenoid valve

Compatibility:

• DJI Agras T100

Package Quantity: 1 Set

Installation Area: Spray boom, nozzle mounting positions

Function: Chemical atomization and electronic flow gating

Part Classification: Replacement component - not a DJI OEM labelled part

Condition: Brand new

Published dimensions and ratings: Disc diameter, coil voltage and current, orifice size, hose barb size, and a droplet spectrum table are not published for this set. Match the assembly against the parts you removed, checking boom clamp diameter, hose barb size, and the electrical connector shell and pin count before ordering. This is a replacement component and is not represented as a DJI OEM labelled part.

Service interval: No hour or tank figure is published, and a fixed interval would be misleading anyway, because disc wear tracks what you spray far more than how long you spray it. Wettable powders and suspension concentrates take material off the disc edge at a completely different rate than solutions and emulsifiable concentrates do. Inspect on a schedule; replace on condition.

Set matching: Supplied as a set. Where both boom positions are being serviced, fit them together rather than one at a time. Matched wear across the boom keeps the left-to-right comparison useful as a diagnostic, and a fresh disc working opposite a half-worn one builds an asymmetry into the swath that no setting will correct.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Centrifugal Spray Nozzle Set with Solenoid Valve is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

💡 Why This Component Matters

Everything upstream of the nozzle exists to serve it. Pump, filters, plumbing, flow meters — all of it is in service of putting the right droplet on the right leaf. When the nozzle drifts off spec the whole system is doing expensive work for degraded results, and the operator pays for it twice: in wasted chemical and in efficacy complaints.

The Centrifugal Spray Nozzle Set helps maintain:

• Target droplet spectrum
• Even, repeatable coverage
• Accurate application rates
• Reduced chemical drift
• Clean solenoid open and close response
• Full spray system output
• Consistent results between tanks
• Predictable service intervals

Without it, operators risk:

• Drift onto adjacent property
• Poor efficacy and callback applications
• Wasted chemical on every tank
• Regulatory exposure from off-spec droplets
• Downtime during peak season
• Aircraft grounded waiting on parts
• Reduced fleet availability
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the droplet. Protect the aircraft. Protect the mission. Protect the season.

This is the last component in a long chain, and everything wrong with it is invisible in the log file. The aircraft records that it flew the plan and delivered the volume, because it did. What it cannot record is what happened to that volume in the last few millimeters before it left the disc. That is why nozzle condition is checked by eye and by comparison rather than by telemetry, and why the operators who stay out of efficacy arguments are the ones who look at their discs on a schedule.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

New condition, correctly described. We describe what we ship and we do not overstate it. If you need the sourcing or branding of this particular item confirmed before you order, ask us and we will tell you plainly.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

What does a centrifugal nozzle do differently from a pressure nozzle? It atomizes by spinning liquid off a disc rather than forcing it through an orifice. Droplet size is set by disc speed rather than pressure, which gives finer control and lets the system hold spectrum across varying flow rates.

What does the solenoid valve do? It gates chemical flow to the nozzle on command from the flight controller, so spray starts and stops cleanly at swath boundaries instead of dribbling.

How do I know the disc is worn? Droplet size drifts off target, coverage streaks, and drift increases in wind you used to fly in comfortably. Inspect the disc edge for scoring or erosion.

Does this fit the T50? No. This is the T100 set. The T50 uses a different front centrifugal nozzle assembly, which we list separately.

Will this fit my aircraft?

This part is supplied for the DJI Agras T100. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Centrifugal Spray Nozzle Set with Solenoid Valve myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

How do I tell whether the problem is the solenoid or the atomizer?

Test them separately, because they fail for different reasons. With clean water in the tank and the aircraft safely on the ground, command spray on and off and listen at the nozzle body for a distinct click. A click with no flow means a blocked or stuck valve; no click at all points at the connector, harness, or driver rather than the valve itself; flow that continues after the off command means the seat is not sealing. Then run the head dry and watch the disc spin up and coast down. Anything wrong with spin-up, balance, or noise is the atomizer, and it has nothing to do with the valve.

Liquid still comes out after I shut the boom off. Is that a failed solenoid or just the line emptying?

Watch how it behaves rather than that it happens. Drain-down is a small amount, tapers off within a few seconds, and stops on its own because the line above the nozzle has emptied. A solenoid that is not sealing keeps producing liquid for as long as the system holds pressure, and it does it again every time you command off. If you can leave the system pressurized and come back to a wet nozzle, the seat is the fault.

How do I judge disc wear without a droplet analyzer?

Get the removed disc and a new one side by side under good light and look at the outer edge from the side, not from above. New, the working edge is crisp and uniform all the way round. Worn, it reads as polished, rounded, thinned, or chipped, and often unevenly so, with more loss on one part of the circumference. That comparison takes seconds and answers the question. Water-sensitive paper across the swath is the next step up if you want to confirm what the wear is doing in the air.

One nozzle sprays thinner than the rest. Does that mean that nozzle is bad?

Not necessarily, and it is worth ten minutes to find out before ordering. A single starved nozzle can also be a partly blocked feed line, a kinked hose at the arm fold, a restricted inline screen on that branch, or a solenoid that opens only partway. Swap that nozzle's feed hose with a neighbor's if the plumbing allows, or pull and inspect the line and screen. If the thin spray follows the nozzle, it is the nozzle. If it stays with the position, the fault is upstream.

Should I replace both, or just the one that failed?

Replace as a set when the failure is wear, and consider replacing just the one when the failure is an event, such as a solenoid that swallowed debris early in its life. The reason wear argues for both is that the two heads have sprayed identical tank mixes for identical hours, so the second one is at the same point in its life as the first. It is also the only way to keep the left-to-right comparison honest, and that comparison is your best field diagnostic.

What should I do to these at the end of a spray day?

Flush with clean water until what comes out of the nozzle runs clear, then run the system briefly with the boom open to clear the lines, and leave it drained rather than wet with product. Dried residue on a solenoid seat is the number one cause of a valve that sticks, and it forms overnight, not over a season. If a cold night is coming, drain the boom properly, because water left standing in a nozzle body and valve can freeze and damage the seat.

Can I clean a sticking solenoid instead of replacing it?

It is worth one careful attempt. Flush it with clean water, let anything caked soften rather than attacking it dry, and use a soft brush only. What you must not do is pick at the seat with wire, a needle, or anything steel. The seat is a sealing surface, and a scratch in it is a permanent leak that no amount of further cleaning will fix, which turns a maybe-recoverable valve into a definitely-replaced one. If it sticks again after cleaning, stop cleaning and replace it.
