Multipurpose Combinatory Oil/Air/Gas/ Pollution Filtration Cleaning Device: U.S. Patent # 4,585,599  

Multipurpose Combinatory Oil/Air/Gas/ Pollution Filtration Cleaning Device: 

This air purification system combines dry and wet filter systems. Dirty air is directed onto the surface of a scrubbing liquid, which is then forced down and into a cleaning liquid which is denser than the scrubbing liquid and not mixable with it. Filters are also provided which continually cleanse the lighter liquid as it is recirculated through the heavier liquid. This system cleanses air of even the smallest particles. In addition to refrigeration and central air conditioning applications, this system will extend engine life when used in cars and trucks, by eliminating oil deterioration. A prototype has been extensively tested and test results are available upon request.  Inventor:   Yanush Czarno, P.O. Box 2064, Miami Beach, FL 33140; (305) 673-0384
