Abstract
A high reliability, non-blocking air filter for filtering large volumes of low pressure air from equipment to be maintained free of dust and impurities while being ventilated during operation is disclosed. The filter media is mounted in a frame having a U-shaped cross section construction, which is attached over an air intake opening of the piece of equipment. The filter media includes a planar base surface and a plurality of projections. The tops of the projections define a surface above said planar base surface for supporting free-flowing articles so as such that these articles do not obstruct the air flow through the air intake filter.
