Compressed Air Foam Generators
DEMA SERIES 294 COMPRESSED AIR FOAMERS combine detergent concentrate with air and water to produce foam of any consistency. Foam is generated instantly and automatically. Fully adjustable for precise detergent-water proportioning as well as foam dryness. Several DEMA Models which are ideal for trucks, trailers, cars and airplanes are shown below. Foam for horizontal and vertical surfaces. No pumps, pressure tanks, electrical wiring or pre-mixing needed. Makes up to six cubic feet of foam per minute and throws foam up to 25 feet using a straight nozzle.
Model 294C: Standard Unit. GHT inlet with screw holes for mounting, or mounts directly on 1/2" pipe.
Minimum pressure for good foam is 50 PSI of water and 40 PSI of air using 50' of 3/4" ID hose.
Capacities:
1 Viscosity CPS to 27 Oz./Gallon
75 Viscosity CPS to 13 Oz./Gallon
220 Viscosity CPS to 10 Oz./Gallon
Note: These are maximum oz./gal. Detergent consumption may be as little as half these figures depending upon its ability to foam.
Nozzle rating - 20-GPM @ 40 PSI Minimum.
