Washable primary filter structure features
Washable primary filter structure featuresWashable primary filters are suitable for primary filtration of air conditioning systems, mainly for filtering dust particles above 5um (micron), generally used for pre-filtration of central air conditioning and centralized ventilation systems, pre-filtration of inlet air of gas turbines and air compressors; also suitable for simple air conditioning and ventilation systems that only need filtrationWashable primary filter structure: 1. Structure style: primary efficiency filter is generally divided into flat type, folding type, letter type, etc. 2. Outer frame material: paper frame, aluminum frame, galvanized plate frame, stainless steel frame. 3. Filter material: non-woven fabric, glass fiber, nylon mesh, activated carbon filter material, metal hole mesh, etc. 4. Product features: a small resistance, large air volume, washable, long service life, strong and smooth outer frame structure. The washable primary filter is not deformed or damaged in poor environments, and can be disassembled to facilitate the replacement of filter material to achieve the purpose of reuse of the frame; the filter material is made of high-quality polyester synthetic fiber, with fluffy and dense fiber structure and high dust collection rate, which better protects its back-end filter and prolongs its service life. 5. Filtration efficiency: The efficiency of the primary filter is divided into G1-G4. 6. Resistance: The initial resistance of the primary air filter is 65~70, and the final resistance is 250~300 Pa. Danze Technology Tip: When the filter reaches or is close to the final resistance, it means we have to replace the filter. 7. Air volume: The rated air volume of the primary filter is determined by the filter area of the primary filter. 8. Replacement cycle: It is recommended to replace the filter once every three months, or the customer can decide the replacement time according to the actual situation. |
