DJI Agras Centrifugal Nozzle Service Kit
Replacement/service kit for compatible DJI Agras centrifugal spraying systems used on T40, T20P, T50 and T25 aircraft. The source configuration shows a centrifugal nozzle-related rotating component together with an inline fluid component, making this kit suitable for technicians servicing the liquid-delivery and atomization path.
Compatibility
- DJI Agras T40
- DJI Agras T20P
- DJI Agras T50
- DJI Agras T25
Confirm the exact nozzle generation, spindle/drive interface, hose fittings and included components against the aircraft before ordering. DJI spray-system revisions can share similar visual architecture without every component being interchangeable.
Purpose
Centrifugal atomization depends on consistent liquid delivery and a mechanically healthy rotating spray component. Wear, contamination, impact, chemical deposits or bearing/drive deterioration can alter spray quality or prevent the nozzle from operating correctly. A service kit gives operators a practical way to replace affected components without treating the entire spray system as a single non-serviceable assembly.
Symptoms That May Lead to Service
- Uneven or abnormal spray pattern.
- Nozzle does not rotate correctly.
- Visible damage to the rotating component.
- Restriction or contamination in the local fluid path.
- Persistent nozzle-related error after connector and wiring inspection.
- Chemical residue or wear discovered during seasonal maintenance.
Diagnostic Guidance
Spray-quality problems can originate from multiple places: tank contamination, pumps, hoses, valves, filters, nozzle motors, discs, wiring and operating settings. Inspect the complete flow path before replacing components. A clogged upstream filter can reduce nozzle output even when the nozzle itself is healthy; conversely, a damaged rotating assembly can create poor atomization despite adequate liquid flow.
Installation & Testing
Power the aircraft down and remove the flight battery. Drain and clean the spray system according to the chemical used. Avoid introducing debris into open hoses. Install components in the original orientation, verify fittings are secure, and test with clean water before chemical application. Observe for leaks, abnormal vibration and inconsistent atomization.
Why This Part Matters
The nozzle is where the aircraft converts liquid flow into the spray pattern delivered to the crop. A relatively small nozzle-system defect can therefore affect application consistency across an entire field. Maintaining clean, mechanically sound atomization components protects both aircraft productivity and application quality.
Who This Is For
- DJI Agras spray operators

FAQ
Is this the entire spray system? No. It is a nozzle-related service kit, not the tank, pump and complete spray plumbing assembly.
Should I test with chemical immediately? No. A clean-water leak and function test is the better first verification after spray-system service.
