紙框初中效折疊式過濾網 產品特性 •濾材是由無紡布棉及合成纖維經特殊混紡制成，具有高容塵量，初期壓損低，風量大之優點； •濾料復合金屬網做成折疊式，給予氣流提供了最大的過濾面積，其過濾面積是一般平面濾網的5倍，可選擇紙外框金屬外框，容易更換，采購費用減少； •耐濕度可達100%； •耐溫80℃； •可選過濾等級:G4.F5.F6.F7.F8。 用途 空調過濾系統預過濾，可延長中效及高效過濾器的使用壽命； 性能參數 specification 標準尺寸 Normal size 實際尺寸 Actual size W*H*W(mm) 額定風量（m³/h） Rated air flow 1.5m/s 2.5m/s 3.0m/s 24*24*1〝 595*595*22 2040 3400 - 20*24*1〝 495*595*22 1785 2975 - 20*20*1〝 495*495*22 1445 2380 - 12*24*1〝 287*595*22 1020 1700 - 24*24*2〝 595*595*44 2040 3400 4250 20*24*2〝 495*595*44 1700 2805 3570 20*20*2〝 495*495*44 1445 2380 2975 16*24*2〝 390*595*44 1445 2380 2675 16*20*2〝 390*495*44 1105 1870 2380 12*24*2〝 287*595*44 1020 1700 2125 24*24*4〝 595*595*90 2040 3400 4250 20*20*4〝 495*495*90 1455 2380 2975 12*24*4〝 287*595*90 1020 1700 2125 Foldaway paper frame filter mesh Speciality: The filtration material is made from non-woven fabrics, and the synthetic fibre .it has the advantage of the large dust holding capacity, the low pressure loss in the initial period and lager air flow. The filtration material compounds with the material net, and is designed into the foldaway, which will provide the current air with the largest filtration area, 5 times’ filtration area as the common plane mesh. Paper frame and metal frame are available, which is convenient for replace; Less purchasing expense The moisture-proof 100%; Heat resistance 80℃; The rank of the filtration: G4.F5.F6.F7.F8. Using: Pre-filter for the air-condition filtration system. It can lengthen the working life of the middle and high efficiency filter.
