Description
Construction
Washable replaceable pleat air filters usually use aluminum alloy or galvanized sheet as the outer frame, with good corrosion resistance and strength. The outer frame is designed to be removable for easy replacement of filter material. The filter material is generally made of green white cotton or polyester fiber and other materials, which not only have a high dust capacity, but also can be cleaned and reused many times
Replacement Cycle
Detection index:
The pressure difference reaches 2 times the initial value
Visible filter material surface dust > 50% area
Typical cycle:
Washable filter material: 2-3 months/time (weekly purge)
Unwashable filter material: 1 month/time
