Product Introduction

The washable aluminum mesh filter packs alternating layers of crimped aluminum screen and expanded metal into an all-aluminum frame. Successive changes in mesh direction create a tortuous air path that brings coarse particles, lint and light oil mist into contact with the large metal surface area. Protective face grids retain the media under elevated face velocity, while drain openings prevent wash water from remaining inside the lower rail. The non-corroding lightweight construction is suited to repeated cleaning where a disposable fiber pad would be consumed quickly.

Key Features

Alternating crimp directions create multiple impingement surfaces without densely blocking the air path.

Aluminum media, face grids and frame keep the assembly lightweight and corrosion resistant.

Rigid expanded-metal retainers prevent the internal screens from shifting during washing.

Drain slots in the frame allow rinse water to leave the media pack before reinstallation.

Customer Product Concerns

Permanent aluminum filters must balance open airflow with enough tortuous metal surface to collect contamination and survive frequent washing.

Disposable media clogs rapidly in oily or lint-heavy intake air.Layered aluminum mesh presents washable impingement surfaces that can be restored with water and suitable detergent.

A dense metal pack creates excessive fan resistance after only moderate loading.Crimped layers maintain open passages and distribute contamination through the filter depth.

Loose internal screens settle and leave an unfiltered path across the top of the frame.Expanded-metal face retainers compress and locate every media layer around the full perimeter.

Rinse water trapped in the bottom channel accelerates staining and microbial growth.Drain slots and an all-aluminum construction support complete drying before the filter returns to service.
