Product Information

Save your equipment from costly repairs and permanent damage with KnockDown Defoamer!

When wet foam loaded with detergent, lint, and soil residue enters the vacuum motor and builds up on the inner walls of the impellers, it chokes the air passage. The moisture from the foam will rust and damage the vacuum motor and armature, reducing vacuum performance and significantly shortening the life of your equipment.


Not only does foam in the vacuum line dramatically reduce suction, but foam buildup in the tank is often sucked up through the vacuum blower and out the exhaust, leaving you with foam-covered carpets, walls, and furniture.


KnockDown Defoamer is an essential product to keep on hand. It breaks down and prevents foam buildup in recovery tanks of truck mounted units, portable extractors, and automatic floor scrubbers.


Consistent use of KnockDown Defoamer saves your equipment from costly repairs. It can be applied directly into recovery tanks, but it works best when picked up through the vacuum hose.


Mix at an economical 12 oz per gallon of water before use!
