Seventy-five liters is a lot of chemical to trust to one piece of plastic. The tank is the single largest working component on the aircraft, and it spends its whole life doing the two things plastic likes least — carrying a heavy sloshing load and sitting in sun and solvent. When it finally lets go, it rarely does it politely on the trailer. It does it at altitude, over a crop, on the one clear morning the forecast gave you.

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.

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 DJI Agras T100 OEM 75L Water Tank is the aircraft's primary liquid reservoir, engineered to safely store and deliver spraying solutions throughout demanding commercial agricultural operations.

As one of the largest structural components on the aircraft, the water tank directly affects spraying efficiency, aircraft balance, mission duration, and overall operational productivity. Designed specifically for the DJI Agras T100, this OEM tank integrates seamlessly with the aircraft's pumping system, plumbing, sensors, frame, and liquid management components to maintain consistent application performance.

Commercial agricultural drones operate in environments far more demanding than typical UAVs. Every flight exposes the aircraft to fertilizer residue, herbicides, pesticides, UV exposure, vibration, transportation, rough terrain, changing temperatures, and continuous loading and unloading of chemicals.

During routine operation, the aircraft may be used for:

• Crop spraying
• Liquid fertilizer application
• Herbicide treatments
• Fungicide applications
• Insecticide spraying
• Orchard operations
• Vineyard treatments
• Specialty crop protection
• Precision agriculture
• Daily commercial spraying
• Multi-drone fleet deployments

Throughout these demanding conditions, the spray tank must remain structurally sound, leak-free, and securely mounted. A damaged tank can compromise both spraying performance and operational safety. Cracks, punctures, chemical damage, impact deformation, or mounting failures may lead to leaks, reduced spray capacity, improper aircraft balance, contamination, or unnecessary downtime.

The OEM 75L Water Tank helps maintain:

• Full 75-liter carrying capacity
• Reliable liquid containment
• Proper aircraft balance
• Consistent pump performance
• Stable spraying operations
• OEM structural integrity
• Secure mounting
• Reduced leakage risk
• Improved operational efficiency
• Long-term aircraft reliability

Manufactured to DJI OEM specifications, this replacement tank restores factory fit, capacity, and compatibility while helping operators maintain dependable commercial performance throughout the spraying season.

The hardest duty this tank sees is not a full load. It is a half load. Seventy-five liters of clean water is roughly 165 pounds, and when the tank is brim full that mass is packed tight and moves very little. Draw it down to half and the same liquid gets a free surface to run on, so every acceleration at the start of a pass and every turn at the end of one drives a wave into a wall and then into a mount. That is why the back half of a load works the structure harder than the front half, and why fatigue shows up around the mounts long before the shell itself looks tired.

Most reported tank leaks are not leaks in the tank. The reservoir seals at four places that have nothing to do with the shell: the lid and its gasket, the outlet or sump fitting where the plumbing leaves, any sensing port let into the body, and the vent path that lets air in as liquid goes out. Each of those is its own part with its own failure mode, and each is far cheaper to put right than a tank. Establishing which of the five surfaces is actually wet is the whole diagnosis, and it takes a paper towel and fifteen minutes.

Polymer tanks do not fail the way metal ones do. Under sustained load they creep, meaning the walls slowly take a permanent set, which is why an older tank stops sitting square in its cradle even though nothing ever hit it. In contact with surfactants and solvents, and with a steady stress on the wall, they also craze: a fine network of micro-cracks that starts as a dulled or slightly milky patch and only later becomes a weep. UV works on the outer skin the same way, taking strength out of the material well before the surface looks chalky enough to worry anyone.

⚙️ Functional Purpose

The OEM 75L Water Tank is designed to safely contain, transport, and supply spraying solution to the aircraft's liquid delivery system.

The component helps:

• Store spray solution
• Maintain full liquid capacity
• Supply the spraying pumps
• Support even liquid distribution
• Maintain aircraft balance
• Reduce leakage
• Preserve spraying efficiency
• Support consistent flow rates
• Maintain OEM compatibility
• Improve mission reliability
• Reduce operational interruptions
• Restore factory performance
• Support commercial productivity
• Improve long-term durability
• Reduce preventable maintenance

Reliable liquid containment is essential for reliable spraying. When the tank maintains its structural integrity, operators can confidently perform longer spraying missions with fewer interruptions and greater application consistency.

A damaged tank may contribute to:

• Chemical leaks
• Reduced tank capacity
• Structural cracks
• Liquid contamination
• Improper aircraft balance
• Pump performance issues
• Increased maintenance
• Mission interruptions
• Unexpected downtime
• Reduced spraying efficiency
• Costly field delays
• Premature component wear

Find out which surface is wet before you order anything. Rinse the tank, dry it completely, and refill it with clean water. Then work the joints in order with a clean white paper towel: run it around the lid seal with the lid closed, around the outlet fitting and its clamp, around every sensing port, and along the lowest seam. A towel picks up seepage far too fine to see and shows you exactly where it came from. If every joint stays dry and the shell still wets, then it is the tank, and now you know.

Do not pressurize a spray tank to hunt a leak. It is a vented reservoir, not a pressure vessel, and shop air will find a way out through a joint that would never have leaked liquid while risking the tank itself. If a static fill is not conclusive, leave it standing full on a clean dry floor for a few hours and check underneath. Slow weeps declare themselves with time, not with pressure, and a damp footprint on dry concrete is easier to read than anything you can do with a gauge.

Take it out empty and take it out supported. Drain the tank, run clean water through the system, and drain again before you touch a fastener; nobody should be handling 165 pounds of awkward, slippery plastic on a trailer deck. Relieve the plumbing, pull the outlet hose and cap it so residue does not run into the airframe, disconnect any sensing leads without dragging them, and note where every strap, pad, and shim sat. Support the tank yourself as the last fastener comes out rather than letting it drop onto the cradle, and never lever a stuck tank against its own flange or a fitting boss.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cracked tank housing
• Chemical leaks
• Impact damage
• Warped tank body
• UV degradation
• Mounting damage
• Punctures
• Stress fractures
• Excessive wear
• Broken mounting points
• Chemical staining
• Deformation
• Internal contamination
• Difficult installation
• Maintenance inspection findings
• Aircraft rebuild projects
• Fleet refurbishment
• Preventative maintenance replacement
• Long-term commercial wear

Field note: inspect the tank FULL, not empty. An empty tank hides everything — a hairline crack in the lower wall or a fatigued mounting boss only opens up under the weight of seventy-five liters, which is why so many operators find a tank "fine" on the bench and then watch it weep in the field. Fill it with clean water, set it on level ground, and walk around it after fifteen minutes looking for beading, wet streaks, or a damp ring underneath. Chemical staining that runs downward from one spot is telling you where the leak is even after the tank has dried. Cracks almost always start at the mounting points and at radiused corners where the load concentrates — check those first. And if the aircraft has started flying nose-high or drifting with a full load when it never used to, look at the tank and its mounts before you chase the flight controller; a tank shifting even slightly in its cradle moves the center of gravity every time the liquid sloshes. Never patch, epoxy, or plastic-weld a spray tank back into service. A repaired tank holds until it is full, hot, and two hundred acres from the truck.

Common causes of tank failure include:

• Impact from rough landings, transport, or dropped equipment
• Prolonged UV exposure causing surface chalking and brittleness
• Chemical attack from aggressive concentrates left standing in the tank
• Fatigue cracking at mounting bosses from repeated load cycling
• Over-tightened mounting hardware distorting the tank flange
• Freeze damage from liquid left in the tank in cold weather
• Abrasion from grit trapped between the tank and its cradle

A damp ring under the aircraft after it sits overnight, with nothing showing during operation: a gravity leak at the lowest point of the system. Standing liquid finds the lowest defect, so look at the sump fitting and the bottom seam before anything else.

Wet only while spraying and dry when parked: that is the pressure side. Look downstream of the pump and at the outlet fitting seal moving under flow, not at the tank shell. A shell defect does not care whether the pump is running.

Chemical smell around the airframe with nothing visibly wet: a weep too small to run. Wipe every joint with a clean paper towel and check the towel, and pay attention to whether the smell is strongest with the tank full.

A dull, milky, or slightly frosted patch in the wall that was not there last season: crazing. It is a network of micro-cracks under the surface, it is where the wall will eventually open, and it does not heal or stabilize. Plan the replacement rather than watching it.

The lid no longer seals cleanly, or it unseats in flight: the gasket has taken a compression set, the lid flange is warped, or the tank rim itself has crept out of round. Check whether a new gasket restores the seal before condemning the tank, and check whether the rim sits flat on a known flat surface.

A tank that no longer sits flat in its cradle or shows a bulged lower wall: creep, usually from being left full and hot for long periods. A tank that will not seat evenly puts point loads into the cradle and cracks from there.

The reported payload figure changed after a tank was removed and refitted, with no change to the weight sensing hardware: the tank is sitting differently in its cradle and part of its load is finding a new path. Correct the seating before you touch the weight system calibration.

Chalky bloom with a rough, powdery feel on sun-facing surfaces: UV degradation of the outer skin. Strength loss runs ahead of the visible change, so a tank that has chalked is one to inspect closely at the mounts and corners rather than one to keep for another two seasons.

🚜 Necessary For

This component is ideal for:

• DJI Agras T100 operators
• Farmers managing spray operations
• Commercial spraying contractors
• Agricultural aviation providers
• Fleet maintenance managers
• Agricultural drone technicians
• DJI Agras repair facilities
• Precision agriculture businesses
• Commercial drone fleets
• Preventative maintenance programs
• Aircraft refurbishment projects
• Daily commercial flight operations
• Emergency repair inventory
• Professional agricultural drone operators

Maintaining a spare spray tank can significantly reduce downtime following accidental impact damage or unexpected tank failure during peak spraying seasons. This is especially valuable during:

• Spring application season
• Summer spraying operations
• Fungicide programs
• Herbicide applications
• Orchard treatments
• Vineyard operations
• Custom application contracts
• High-acreage commercial work
• Multi-drone fleet deployments

Aircraft that have taken a strike, a rollover on a trailer, or a hard set-down where the tank absorbed the impact and the damage may not be visible until the tank is full.

Fleets that keep a spare tank on the shelf so a weeping reservoir is a swap between loads instead of a machine parked for the rest of the application window.

Operations moving off a season of hot, concentrated programs, where crazing and chalking have appeared and the tank is being retired on evidence rather than on failure.

Aircraft coming out of winter storage where liquid was left in the system, since freeze damage typically shows itself on the first full fill of the year.

💡 Why This Part Matters

The spray tank is one of the hardest-working components on every DJI Agras aircraft. Every spraying mission depends on the tank maintaining its structural integrity while carrying a full chemical load through vibration, repeated filling cycles, transportation, and demanding agricultural environments.

Although the tank may appear to be a simple reservoir, it directly affects aircraft productivity, spraying consistency, operational efficiency, and overall fleet reliability. A compromised tank can result in chemical leaks, reduced capacity, poor spraying performance, unexpected maintenance, and costly downtime during critical application windows.

The OEM 75L Water Tank helps maintain:

• Full spraying capacity
• Reliable chemical containment
• Consistent liquid delivery
• Proper aircraft balance
• Factory structural integrity
• Long-term durability
• Reduced leakage risk
• Improved spraying efficiency
• Professional fleet readiness
• Maximum aircraft uptime
• Dependable commercial performance
• Lower long-term operating costs

Without a properly functioning spray tank, operators risk:

• Lost spray solution
• Reduced application efficiency
• Aircraft imbalance
• Pump performance issues
• Chemical contamination
• Mission delays
• Unexpected downtime
• Higher maintenance costs
• Reduced fleet productivity
• Missed weather windows
• Lost revenue
• Lower operational confidence

In service:

• Fill with clean water first and check for leaks before you ever put chemical in a new tank
• Seat the tank squarely in its cradle and torque the mounting hardware evenly — do not crank one side down to close a gap
• Confirm the fill port, lid, and level sensor all seal and read correctly before the first loaded flight
• Rinse the tank at the end of every spray day; standing concentrate is what kills tanks early
• Store the aircraft out of direct sun when practical — UV is the slowest and most certain form of tank damage
• Hover the aircraft loaded and confirm it holds level before committing to a mission

For commercial operators, protecting the aircraft's spraying system begins with protecting its largest and most essential liquid-handling component. The DJI Agras T100 OEM 75L Water Tank restores factory liquid capacity, maintains reliable spraying performance, supports professional fleet maintenance, and helps keep commercial agricultural operations moving throughout the busiest application seasons.

Carry the load. Seal the chemical. Hold the balance. Spray it clean.

The two habits that decide how long one of these lasts are what you leave in it and where you park it. Rinsing at the end of the day removes the concentrated residue that keeps working on the polymer overnight, and it matters most after the hot products, not after the easy ones. Where the aircraft sits between jobs matters just as much: a tank baking full in direct sun is under sustained load, elevated temperature, and UV all at once, which is the exact combination that turns a stress point into crazing.

Handle a new tank as carefully as you would handle the one you are pulling out. Do not drag it across a trailer deck or a concrete floor, because a scuffed or gouged wall is a stress raiser and that is where the first craze will start. Keep it out of the sun until it goes on the aircraft, do not stack anything on it, and do not use it as a step, a seat, or a bench. Check the cradle pads and straps before the new tank ever touches them, since anything hard, sharp, or displaced under the tank becomes a point load the moment you fill it.

Replace this one on evidence and not on a clock, but understand which evidence is worth acting on early. Crazing, a wall that has taken a set, a rim that no longer sits flat, and any damage at a mounting boss are all reasons to plan a replacement now, in the shop, while there is time. A tank that reaches the point of visible weeping has already been leaking vapor and fine residue into the airframe for a while. Operators who lose a tank mid-season almost always had one of those signs and read it as cosmetic.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 OEM 75L Water Tank? It is the genuine DJI OEM 75-liter spray tank for the DJI Agras T100 — the aircraft's primary liquid reservoir, storing and supplying spray solution to the pump and liquid delivery system as a direct-fit factory replacement.

Which DJI Agras models does this 75L water tank fit? This OEM tank is specified for the DJI Agras T100, integrating with the T100's pumping system, plumbing, sensors, and frame mounting exactly as the factory tank does.

How do I check a DJI Agras T100 spray tank for cracks or leaks? Inspect it full, not empty. Fill the tank with clean water, set it on level ground for fifteen minutes, and look for beading, wet streaks, or a damp ring underneath — a hairline crack or fatigued mounting boss often only opens under the weight of a full 75-liter load, which is why a tank can pass an empty bench check and still weep in the field.

Why does my T100 fly nose-high or drift with a full tank when it never used to? Check the tank and its mounts before chasing the flight controller. A tank shifting even slightly in its cradle moves the center of gravity every time the liquid sloshes, so a new full-load handling change calls for a tank and mounting inspection first.

What are the signs a DJI Agras T100 water tank needs replacing? Cracked housing, chemical leaks, a warped or deformed tank body, UV chalking, punctures, and broken mounting points. Cracks almost always start at the mounting bosses and radiused corners where load concentrates, and chemical staining that runs downward from one spot marks the leak's origin even after the tank has dried.

Can a cracked DJI Agras spray tank be repaired with epoxy or plastic welding? No — never patch a spray tank back into service. A repaired tank holds until it is full, hot, and far from the truck, and seventy-five liters of chemical letting go at altitude costs far more than the replacement tank.

What causes DJI Agras T100 spray tanks to fail early? Standing concentrate left in the tank, prolonged UV exposure, freeze damage from liquid left over winter, transport impact, over-tightened mounting hardware distorting the flange, and grit trapped between the tank and its cradle. Rinsing the tank daily and storing the aircraft out of direct sun are the two cheapest life-extenders.

How do I know my 75l water tank needs replacing? The indicators operators most often report are: cracked tank housing; chemical leaks; impact damage; warped tank body; uv degradation; mounting damage. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

How do I tell a cracked tank from a leaking fitting?

Dry the whole assembly, fill with clean water, and check the joints one at a time with a clean white paper towel: the lid seal, the outlet fitting and its clamp, every sensing port, and the lowest seam. Seepage shows on the towel long before it is visible on the plastic. If all the joints come back dry and the shell still wets, the tank is the problem. If a joint wets, you may be looking at a gasket or a clamp instead of a reservoir.

Why did my tank crack when it never took a hit?

Polymer reservoirs fail by stress cracking as often as by impact. A steady load on the wall, contact with surfactants and concentrates, heat, and UV together produce a network of micro-cracks that starts as a dull or milky patch and eventually opens. Nothing has to strike it. That is also why the cracks appear at mounting bosses and radiused corners, where the wall carries the most stress for the longest time.

Do I need to re-check the payload reading after fitting a new tank?

Yes, before you trust it. The weight system reads the force that reaches its sensing elements, and a new tank that sits even slightly differently in its cradle changes how that load is carried. Fill with a measured volume of clean water and compare the reported figure to what you put in. If it is off, correct the tank seating and the mounting first, and only then look at the weight system itself.

Can I run partial fills to save flight weight?

You can, and operators do it constantly, but be aware of what it does. A part-full tank has a free liquid surface, and that surface moves hard on acceleration and on turns at the end of a pass. It is more punishing on the tank walls and the mounts than a brim-full load, and it changes how the aircraft handles as the level drops. Nothing wrong with the practice; just do not let it fool you into thinking a light load is an easy load for the airframe.

Is it safe to pressure-test the tank with shop air?

No. It is a vented reservoir designed to hold a static column of liquid, not internal pressure, and air testing can both damage it and mislead you by pushing past joints that would never pass liquid. The static fill test with clean water tells you what you need to know. If a weep is too slow to catch, leave the tank standing full on clean dry concrete for a few hours and read the footprint underneath.

How should the tank be stored over the winter?

Drain it completely, including the plumbing, so nothing is left to freeze and split a fitting or a low point. Rinse it out before it goes into storage rather than after, since residue left to dry inside is harder on the polymer and harder to remove in spring. Store it out of direct sun, upright, with nothing stacked on it, and leave the lid loosely fitted rather than sealed tight so it can breathe and so the gasket is not held compressed all winter.

What should I inspect on the cradle and straps while the tank is out?

Look at the pads for compression, tearing, or missing sections, and at every strap or clamp for stretch, frayed webbing, and cracked hardware. Check the cradle itself for cracks around fastener holes and for any high spot, burr, or trapped debris that will bear against the new tank. This is the one moment in the season when all of it is visible, and a tank sitting on a damaged cradle will develop exactly the same failure the last one did.

Is the DJI Agras T100 OEM 75L Water Tank also available in Canada? Yes. Ares Acres ships this T100 OEM 75L Water Tank to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).
