Welded Wire Pleated air filters
The galvanized metal mesh protection grid of the metal frame air pre-filter is welded and forms an inverted frame. Then the V-shaped filter cotton is fixed in the middle of the protection grid. The outer frame is made of aluminum alloy or other metal. The metal frame air pre-filter is sturdier than other kinds of pre-filters.
Metal frame air pre-filters have low initial resistance, large dust holding capacity, can be cleaned several times, and the filter cotton can also be replaced. Therefore, it’s environmentally friendly and economical. It can be widely used in pre-filter system such as clean rooms, HEPA air filter, air compressors, central air-conditioning fresh air handling unit and ventilation systems, and computer room dedicated constant temperature and humidity air conditioning units.
- Filter media:
- The filter media is special blended by non-woven cotton and synthetic fibers to ensure high dust capacity and high efficiency.
- Protection grid:
- Galvanized metal mesh welded to form an inverted frame.
- Frame:
- Optional galvanized iron frame, aluminum alloy frame or stainless steel frame.
