SILVER FRAME ELECTROSTATIC FILTER

Our Silver Frame filters are made from a single piece of roll-formed aluminum fastened together at one corner with a single rivet. This frame type is more cost-effective than the gold frame, but is not quite as strong and sturdy. Silver Frame filters are available in either 1/2″ (custom only), 1″ or 2″ depths. The 1/2″ (7/16″ Actual) silver rigid framed filters have 2 layers of polypropylene between 2 layers of expanded steel for improved air flow and rigidity. Our 4″ rigid framed filters are configured with the same construction as the 1″ Electra silver, but with a 1.5″ white polyester ultra high loft impingement filtering center layer.

This filter has the same ratings as its one inch counterpart. We also have 1″ & 2″ filter frames and disposable pads that consist of a roll formed metal frame with one layer of expanded metal support secured to one side. The filter material is tucked into the frame and is held by the fibers catching on the expanded metal support and the air flow. When soiled, it is easily removed for disposal and replaced by a clean piece of filter material pad.
