ABSTRACT:
Sanding and screening are steps in floor finishing that produce large quantities of fine dust which is difficult to remove and which plugs porous filter elements of dust collection systems. Dust collection is enhanced with a floor screening attachment for a floor machine. A vacuum system with a liquid filtering medium is provided to collect dust produced during screening. A dust collection unit is also disclosed to collect and separate sawdust produced by sanding which can cause foaming of a liquid filter medium.
