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 Filters
HydraMaster filters are designed to trap lint that would normally collect at the
bottom of your vacuum tank. These filters should be emptied at the end of each job.
This will eliminate the build-up of much of the debris in the tank.
