Airofog aerosol generator UM-2 is a professional foggers developed to withstand the ardous field conditions encountered by private pest control applicators or governments undertaking public health operations to control mosquitoes and flies. Thus, such foggers are often applied in the field of plant protection, pest & vector control, and agriculture.

The engine is covered by a worldwide warranty supplied from Briggs & Stratton Corporation.

Advantages include:

Remote operation from a 5m cable cab-mounted control unit for engine starting and stopping, individual spray head on/off, solution tank and solution line system flushing, and light alarming when solution or flushing tank is empty.

High-capacity air filter unit with intake suitable for dusty environments.

Specially designed double turbine nozzle avoids blockage when using wettable powder suspensions or other flowable formulations.

Safety interlock ensures that spray head can only operate while blower is running correctly, which eliminates the accidental discharge of insecticide.

All parts in contact with chemicals are made of stainless steel, Teflon TM , Viton TM , PE, and PA for maximum chemical resistance and durability.

UAirofog UM2 ULV aerosol generator

Airofog vehicle-mounted ULV cold fogging machine (ULV aerosol generator), hereinafter referred to as “fogger”, uses pre-mixed solutions or chemicals mixed with carrier. As all components exposed to solution are made from corrosion-resistant materials like stainless steel, Teflon, polyethylene and etc., all approved chemicals that do not attack such materials can be used.

The selection of chemical preparation and carrier is subject to legally binding regulations and the manufacturer’s guidelines.

Insecticide must only be sprayed while the vehicle is moving within the treatment area. When in stationary position, direct the fog along passageway or cover the plants in the fog affected area.

The fogger suits for following purposes and applications:

• vector and insect control
• pest control
• public health
• plant protection with pesticides and fungicides.
• stock protection
• Hygine and disinfection
• deodorization

A combustion engine drives the side channel blower by 3 x V-belts. The side channel blower is maintenance free and corrosion resistant. Compressed air operated from the side channel blower is well matched to the narrow-bore solution nozzle, bringing about the advantage of producing comparatively small air throughput at a high compression ratio.

The spray nozzle (atomizer) works in two stages: the first step is to break up the liquid at a high velocity. Then at the end of a short conical diffuser, compressed air enters again acting in an opposite direction and provides a better break up of the droplets. The stream of droplet is dispersed without touching the inner surface of the solution nozzle. Thus wettable powder suspensions can be applied without the danger of blocking nozzle.

Control of the throughput is done by a flow meter in which a regulating valve permits an infinitely variable output max. 40 l/h showing by a transparent tube with scale and a floating ball.
