Anti-Drift Air Curtain FM-12 / FM-16 / FM-20

The DUOJIA Anti-Drift Air Curtain is a precision spraying accessory available in FM-12, FM-16, and FM-20 Air Curtain Boom models. It uses a cross-flow fan to create an air curtain wall along the spray boom behind the nozzles, helping reduce droplet drift while improving droplet penetration and coverage.

The system is designed for field spraying, high-speed spraying, low-volume spraying, and spraying applications requiring independent boom section control. Compared with airbag-type air curtain booms, it provides lower energy consumption, higher air velocity, slower air velocity decay, and independent control of air curtain on/off or air speed for each boom section.

Key Features

• Cross-flow fan air curtain — Creates an air curtain wall along the boom behind the nozzles.
• Drift reduction — Reduces droplet drift by 80% and saves 30% of pesticide.
• High-speed operation — Maximum allowable travel speed is ≤ 15 km/h.
• Wind-condition operation — The system can operate under external wind conditions below Level 4.
• Secondary atomization — Refines droplet size, improves penetration and coverage, and supports low-volume spraying. The source specifies 50% water savings compared with conventional boom sprayers.
• Independent section control — Each boom section can independently control air curtain on/off or air speed.
• Adjustable air curtain angle — The angle can be adjusted according to natural wind conditions to support canopy penetration.
• Cross-flow fan configuration — Compared with airbag-type air curtain booms, the system provides low energy consumption, high air velocity, and slower air velocity decay.

Frequently Asked Questions

What models are available for the Anti-Drift Air Curtain?

The product is available as the FM-12, FM-16, and FM-20 Air Curtain Boom.

What type of fan does the system use?

All three models use a cross-flow fan to create the air curtain behind the spray nozzles.

What is the maximum allowable travel speed?

The maximum allowable travel speed is ≤ 15 km/h for FM-12, FM-16, and FM-20.

Can the air curtain be controlled by boom section?

Yes. Each boom section can independently control the air curtain on/off or air speed.

What fan drive types are available?

The documented options are a DC 48 V brushless motor or an AC 220 V motor.

Which crops are supported?

The supplied specifications list rice, wheat, cotton, corn, soybean, etc. For Xinjiang cotton, the documented configurations are 5-film width for FM-12, 7-film width for FM-16, and 9-film width for FM-20.
