Abstract

An air flow system for removing airborne particulate material includes a bank of filters through which air is moved in one direction, thus depositing particulate material on an air input side of the filters. A vacuum head associated with a secondary vacuum system is intermittently applied in a reciprocating movement to selected portions of the air input side of the filters for cleaning them, while the remaining portions of the filters continue to operate in the normal manner without interruption. Both the filters and the vacuum head are provided with integrally formed interengaging guide means which facilitate this operation.
