Hobbying XRotor SPRAY 9L Centrifugal Nozzle for Agricultural Drones — 9 L/min, 500W, CAN ESC, 35–500 µm

Overview

Hobbying XRotor SPRAY 9L is a centrifugal spray nozzle designed for agricultural drones and crop protection applications. The unit integrates a brushless pump and CAN-enabled ESC to deliver precise atomization with a maximum flow of 9L/min and droplet diameter range down to 35m, enabling spray coverage of approximately 4~12 m depending on flight speed and operating settings.

Key Features

• Brushless centrifugal nozzle with extended pump life (approximately 35 times a standard pump; pump life >500 hours as specified).
• High-efficiency atomization: droplet diameter range 35m to 500m for fine, uniform droplets.
• Maximum flow 9 L/min; rated flow 5 L/min (documented system values).
• Integrated protections: temperature protection, overcurrent protection and start-up voltage protection.
• ESC control: PWM and CAN support; throttle travel fixed 1050950 s (no throttle travel calibration supported).
• Waterproof and sealed design with IPX6 protection level and proven corrosion resistance (72 h NSS salt spray test reported).
• Modular mounting: compatible with X9 / X11 / X13 / X15 power mounts and designed for easy installation and transport.

Specifications

Applications

Designed for agricultural drone spraying and crop protection tasks requiring fine atomization and wide coverage: crop foliar application, orchard and field spraying where precise droplet size and flow control are required.

Usage Notes

• The nozzle must not run idle. The water pump must be turned on while the nozzle is running so spray liquid circulates and cools the nozzle motor.
• Turn the nozzle off after the spray liquid is depleted. Some flight controllers may not automatically stop a centrifugal nozzle and require manual shutdown.
• After each operation, fill a container with clean water and cleaning agent, activate the centrifugal nozzle, spray one container of water and then allow the nozzle to idle for 30 seconds to remove residual chemicals and prevent corrosion, solidification and bearing damage.

Details

9L centrifugal spray nozzle includes a top adjustment knob and a multicolor cable with connector leads to simplify wiring and installation.

Centrifugal nozzle provides a 9 L/min flow and up to 12 m spray width, enabling roughly 14.9 mu per minute coverage at about 13.8 m/s flight speed.

Centrifugal 9L SPRAY nozzle produces a uniform fine mist with droplet sizes down to 35 µm to support deeper canopy penetration and even coverage.

Droplet distribution centers on a V50 of about 160.4 µm (V10 ≈ 88.4 µm, V90 ≈ 297.6 µm), helping assess spray coverage and drift characteristics.

Hobbying XRotor SPRAY nozzle provides broad agrochemical compatibility, compatible with common pesticides, fertilizers and adjuvants to simplify mixing and application.

Modular folding nozzle assembly offers easy installation and plug‑and‑play compatibility with X9/X11/X13/X15 power mounts without needing to purge air.

COMBO-SPRAY-9L-18S centrifugal spray head accepts an 18S LiPo, weighs 495 g and supports up to 9 L/min maximum flow for agricultural drone applications.

ESC model HW5116_YT1_V1.2 supports CAN and PWM control with a 1050–1950 µs throttle range, 4 A continuous and 10 A burst current for motor drive management.

Environmental ratings include IPX6 protection, 0–50°C operating range and 5–95% relative humidity, while the droplet-size data shows a median (V50) near 100 µm for spray planning.

Centrifugal nozzle operation requires the water pump to run with the nozzle, the nozzle must be turned off after liquid is finished, and the unit should be flushed with clean water and idled for 30 seconds to remove残留s.
