Electro-Static Prefilter

Metal Mesh Efficincy versus Permatron filtersThe Permatron prefilter significantly improves the capture of the larger 10+ micron particulate. By effectively removing this larger particulate, the collector cell more effectively captures the smaller particulate.

The improved capture of large particles will reduce the occasional spark. Also the need to wash the cells will be extended. The Permatron prefilter has a low 0.09 wg air resistance making it interchangeable with the metal mesh at 0.07 wg.

A quick cleaning of the prefilter is recommended once a month. Simply vacuum or rinse with a hose. Washing the cells would be recommended every 6 months. See brochure for more info.

Quality Construction

Permatron rugged galvanized steel framePermatron prefilters and carbon filters are constructed very durable. They do not easily kink or push out of square. They are not flimsy like the plastic frame.

The prefilter polypropylene weave is drawn tight by the steel frame. Additionally the prefilter is reinforced with an embedded galvanized steel grid. Very good quality.
