Ultra-Low Volume

U.L.V. is an abbreviation for the term Ultra Low Volume. This designation refers to treating areas with relatively small amounts of chemicals or formulations in an aerosol state.

Occasionally ULV Foggers are called Aerosol Generators or Cold Foggers since no heating of the formulation is necessary.

The range of sizes for micron particles or droplets created in a aerosol fog has been the subject of considerable discussion and evaluation since ULV Foggers entered the marketplace in the 1970's.
