ANTIFOAM is a potent silicone-type anti-foam additive. It is designed to quickly break down foam and bubbles that accumulate in the recovery tanks of hot water extraction and automatic scrubbing machines where foam creates problems. Foam build-up reduces the holding capacity of recovery tanks and causes time to be wasted in emptying the tank. If foam rises in the tank and enters the vacuum motor, damage may result. ANTIFOAM eliminates these problems.
