ASHRAE Extended Surface Pleated Panel Filters

This medium efficiency filter is strong and has a large filtration area, which maintains good filtration effect under high humidity and reduces fiber fallout. The human fiber and glass fiber filter with excellent dust catching power is supplemented by a strong expansion mesh to effectively reduce the fallout of micro dust on the air outlet surface.
The reinforced metal mesh on the air outlet filter will not fall off due to tugging and vibration, and is tightly adhered to the outer frame to prevent air leakage.
