The model 18-20 was first manufactured in 1990 and has been very well received in the market place. The designation originated because this model utilizes a 18 HP engine, which enables application of insecticides at vehicle speeds up to 20 miles per hour. The 18-20 produces the correct particle size to meet all insecticide label requirements at vehicle speeds up to 20 miles per hour.

Model 18-20 surpasses most other foggers for two important reasons. One, a new-generation overhead, V-twin cylinder engine (with throttle down feature) produces fewer emissions, consumes less fuel, and has longer service intervals than conventional ‘L’ head engines. Two, our Triple-V Belt Drive feature reduces blower RPM more than 25%. This design extends blower life and creates a quieter operating fogging machine.

The newest technology for use with ULV foggers utilizes G.P.S. for Speed Compensation Flow Control of insecticide output. The Model 18-20 is available with these advancements, including monitoring and recording of adulticide applications and tracking of vehicles.
