First-time efficiency filter paper box, aluminum frame early efficiency filters, cheap

Disposable paper box early efficiency filters, early aluminum frame efficiency filters, early cheap disposable paper box early efficiency filter efficiency filter disposable paper box Features 1, frame made of pasteboard boxes or waterproof paper; 2 , the filter is pleated folds forming one side of enclosure, the fit is good, solid structure; 3, low cost, light weight, versatility, aesthetics and environmental protection; disposable paper box applications early efficiency filters are used ventilation systems The pre-filter, limit use to a relatively dry ventilation system. Product features: ◎ This series is 100% synthetic filter media, the average efficiency (colorimetric) in 30% to 35%; weight rule of 90% -93%; ◎ This filter is bonded to the metal mesh the outlet end to prevent vibration, so consistent pleating; ◎ filter frame is made of sturdy, moisture-proof cardboard box. It does not deform in normal operating environment, cracked, twisted; ◎ mesh filter made in part by the medium discounts, thereby increasing the filtration area, reducing the filter resistance, reaching more than tiled filter life Long effect; Uses: ◎ central air conditioning and ventilation systems fresh air unit; ◎ program-controlled switches, and dedicated computer room air conditioning units; ◎ especially suitable for painting systems, paint shop and pre-filter air compressor and gas turbine pre-filter systems; ◎ high efficiency filter pre-filter system; ◎ widely used in office buildings, shopping malls are concentrated buildings, hospitals, airports and general industrial plant or clean room ventilation system filters and other places. Zhuowei purify air purification unit specializing in production and sales of junior high efficiency air filters, clean room end of the high efficiency filter, filter, purification equipment, our goal is to allow customers to use the product, "domestic prices, imports of quality", we Advantage: cost-effective, short delivery, good as gold, courteous service!
