The vacuum tank is protected from overflowing by a vacuum tank float kill
switch. The switch is not activated by foam, only by liquid.
VACUUM TANK FILTER BAGS
HydraMaster filter bags are designed to trap lint, sand and dirt that would normally
collect at the bottom of your vacuum tank. The use of these bags, if emptied at the
end of each job, will eliminate the build-up of much of the debris in the tank. The
drawstring top of these bags is designed to be slipped around the incoming dirty
water inlet in the vacuum tank.
