HEPA Air Filter

HEPA Air Filter

The Aerostar HEPA (High Efficiency Particulate Air) filter is constructed with a 16 gauge galvanised or stainless steel frame with a continuous band of media pleated back and forth over corrugated aluminium separators. These filters contain a two-part polyurethane, which assures a positive seal of the media pack and frame. The interlocking frame design with sealant placed behind the top and bottom flange allows unobstructed airflow and ease of filter handling.Available for high temperature applications by using a different frame configuration with high temperature sealant and gasketing.

Benefits

The Aerostar HEPA filter's corrugated aluminium separators have proven to have 3 to 4 times more support to the media than other types of construction, thereby allowing use in higher humidity environments.These separators assure even pleat spacing for controlled laminar airflow. The hemmed edges on the aluminium separators and square pleat design reduce possible pleat damage.

Aerostar HEPA filters are UL 900 class 1 to meet strict fire codes. The HEPA HT filters are UL 900 class 2. In addition, filters, 99.97% DOP and higher, are tested on our CIPAT (Computer Integrated Particulate Air Test) duct to assure compliance with overall efficiency specifications. The filters are tested with PAO (poly-alpha-olefin), approved by the US Army and Surgeon General as a suitable replacement for DOP.

Applications

The Aerostar HEPA filters remove a broad range of airborne contaminants, including fine dust, smoke, soot, pollen and radioactive particles. HEPA filters are used in final filter applications including hospitals, electronics, nuclear, pharmaceuticals, laboratories, aerospace, food processing and optics. They can also be used as prefiltration in cleanroom environments and other critical applications for final HEPA, ULPA and SULPA filters.
