For dusty, gritty applications, Kato Engineering offers air-filtered generators. Filters on these machines remove over 78 percent of the particles with diameters over 5 microns.

Air filters and mounting frames are made from stainless steel to prevent rusting and corrosion. The filters can be easily removed for cleaning with steam or soapy water.

A differential pressure safety switch is included. If the filter becomes clogged, the switch actuates. The switch can be connected to an alarm, indicator lights or shutdown circuitry.
