Dry Filter

A ZERO Dry Filter contains a set of cotton sateen tubes; the higher the cfm rating, the greater the number of tubes. With a Dry Filter, the operator periodically stops blasting, turns off the exhauster motor, and shakes a handle to knock the dust from the insides of the tubes into a tray at the bottom of the Dry Filter. From time to time, the operator must empty the tray. Manual tube shaking and dust disposal activity relegate the Dry Filter to light- and medium-duty manual blasting applications.
