First plate efficiency filters, G3G4 grade primary filter, washable coarse dragon skeleton too ..

Plate Primary filter, G3G4 grade primary filter, washable dragon skeleton coarse filter early efficiency filter label: width × height × thickness / efficiency such as 595 × 490 × 46 / G4 Width: filter installation The horizontal dimension mm; Height: vertical dimension mm filter during installation; thickness: filter installation dimensions mm along the wind direction; how to choose a primary filter selected the desired filtration efficiency, G1-G4, such as the special needs of a higher level of filtering can also produce F5-F9; to determine the filter frame materials, paper-box (waterproof type or ordinary type), aluminum frame, galvanized frame and stainless steel folding frame; determining whether the filter grille? If so, can be divided into single-sided and double-sided grille, grille are made of galvanized wire mesh and aluminum prism networks; to determine the required size of the filter frame, folding high (high discount generally 21mm, 46mm, 96mm) and Whether the installation location suitable picture frame dragon skeleton early early efficiency filters effect filters picture frame Features 1, a removable aluminum plate frame /, with aluminum or plastic rectangular fixed angle, rugged smooth, make sure filters under poor working environment nor As deformed or damaged; 2, frame with removable design, easy to replace the filter in order to achieve the purpose of re-use framework; 3, picture frame filter ribs, further enhances the filter robustness, minimum drag for maximum dust holding capacity; 4, non-woven, polyester fibers, can be reused many times to clean, long life; 5, fluffy gradually dense fibrous structure, effectively extending its rear end in effect filter life. Large building ventilation and air conditioning system applications offices, meeting rooms, hospitals, shopping malls, airports, etc., centralized air conditioning system pre-filtration of ordinary industrial plant or clean room. Early effect washable filter Type Dimensions (MM) Rated air flow efficiency early resistance Recommended final resistance ZW-001 595 * 595 * 46 3600m3 / h G4 (35%) ≤65Pa ≤130Pa ZW-002 295 * 595 * 46 1500m3 / h ZW-003 492 * 595 * 46 3200m3 / h ZW-004 492 * 492 * 46 3000m3 / h special sizes and specifications available upon request.
