The progressive density of the glass fibers gradually retains the particles, ensuring low pressure drop and greater durability.

These are disposable filters, manufactured with a cardboard frame and printed cardboard screen or perforated screen to support the filter element, which guarantees greater resistance and dimensional stability.

They have a high accumulation capacity due to the large effective filtering area. They are recommended for high air flow rates, combined with a high concentration of particulates.
The filter media support frame is made of galvanized steel sheet, aluminum or stainless steel and has an exclusive pressing system in the frame, ensuring its watertightness and the full use of the filter media.

Pleated Card Filters are based on inertial separation. This concept causes the flow of charged air to change direction several times, with the denser particles being retained on the walls while the flow of “clean” air exits through the side holes.
