Produces a true dry fog at a particle size of .25 to 50 microns. Small particle size allows complete penetration of contaminated surfaces as well as reduction of airborne odor particles.

The Thermo-Gen® can fog 0-14 gallons of water or oil-based counteractant, such as Thermo-55®, or Thermo-2000® per hour. Gasoline powered. Removable formulation tank, which holds 68 ounces of fuel or enough for 1.25 hours of use. Comes with spare parts, filtered funnel, fuel pitcher, operation manual and a maintenance and operation video. This improved unit incorporates a specially designed cut-off system for added safety.
