Air-Assisted Spray Boom FM-12/FM-16/FM-20 | Duojia

The Air-Assisted Spray Boom is a wind curtain agricultural spraying boom developed for field-crop spraying applications. The FM series combines a spray boom with a transverse flow fan system to provide an air-assisted spraying configuration around the nozzle area.

Three configurations are available: FM-12, FM-16 and FM-20. They provide boom lengths of 12 m, 16 m and 20 m respectively, with corresponding differences in airflow volume, total fan power, nozzle quantity and operating efficiency.

The spray boom uses 110° flat fan nozzles at a 50 cm spacing. The fan system can use either a DC48V brushless motor or an AC220V motor, while hydraulic systems are used for boom lifting and folding.

The FM series is intended for agricultural spraying operations involving crops such as rice, wheat, cotton, corn and soybean. The available configurations allow buyers to select a boom length and fan capacity according to their field operation requirements.

For B2B buyers, the product is relevant when an agricultural spraying system requires a boom-mounted wind curtain or air-assisted configuration rather than a conventional spray boom alone.

Key Product Features

Transverse Flow Fan Wind Curtain

The FM series uses a transverse flow fan structure as the air-generation component of the wind curtain system. The fan provides an airflow volume that corresponds to the selected boom configuration.

This configuration is intended to support air-assisted spraying around the spray boom and nozzle area. Buyers evaluating the product should consider the fan configuration together with the required boom length and crop application.

110° Flat Fan Nozzles

The spray boom uses 110° flat fan nozzles with a nozzle spacing of 50 cm. This provides a defined nozzle arrangement along the boom for agricultural spraying applications.

The nozzle configuration is particularly relevant when buyers are evaluating spray coverage requirements and the integration of the boom with the intended spraying operation.

Hydraulic Boom Lifting

The boom lifting system uses hydraulic lifting. This allows the boom assembly to be raised or lowered through the hydraulic mechanism provided in the product configuration.

For equipment integrators and agricultural machinery buyers, the hydraulic lifting arrangement is an important configuration point to confirm during equipment matching.

Hydraulic Boom Folding

The FM series uses hydraulic folding for the spray boom. The folding function is part of the boom structure and should be considered when evaluating equipment installation, field operation and transport requirements.

The actual installation and integration arrangement should be confirmed according to the customer's equipment configuration.

Multiple Boom Length Configurations

The FM series is available in three boom lengths: 12 m, 16 m and 20 m.

The three configurations also have different fan airflow volumes, fan power levels, nozzle quantities and listed operating efficiencies. This gives buyers several configuration choices for different field spraying requirements.

Two Fan Drive Options

The fan drive form is specified as either a DC48V brushless motor or an AC220V motor.

The appropriate drive configuration should be confirmed according to the supporting agricultural machinery, available power system and actual equipment integration requirements.

Product Benefits

The FM series provides a boom configuration that combines conventional nozzle spraying with a fan-based wind curtain system. This can be considered by buyers looking for an air-assisted approach to agricultural spraying rather than a conventional boom arrangement alone.

The three available boom lengths allow buyers to select a configuration according to the intended operating width. The corresponding fan airflow and power configurations also provide different equipment configurations within the same FM product series.

Hydraulic lifting and folding provide integrated boom movement functions, while the 110° flat fan nozzle arrangement and 50 cm nozzle spacing establish a defined spraying layout.

For agricultural machinery manufacturers, equipment integrators and B2B distributors, the product can also be evaluated as a spraying boom component for integration into a suitable agricultural spraying platform, subject to actual equipment design and configuration.

How the Product Works

The FM series combines a spray boom, spray nozzles and a transverse flow fan.

During operation, the spray boom provides the mounting structure for the 110° flat fan nozzles. The nozzles are arranged at 50 cm intervals along the boom.

At the same time, the transverse flow fan generates airflow for the wind curtain system. The fan is driven by either a DC48V brushless motor or an AC220V motor, depending on the selected configuration.

The boom is raised and lowered hydraulically, and hydraulic folding is used for the boom folding function.

The FM-12, FM-16 and FM-20 versions use different boom lengths and corresponding fan airflow and power configurations. Buyers should therefore select the configuration based on the required spraying width, crop application and supporting equipment.

Technical Specifications
