Supply wire picture frame early effect of a wholesale air filter air filters Tianjin early effect of early prototyping Tianjin early effect efficiency air filters in effect introduces a high efficiency filter, pre-filter description: Primary filter for air conditioning of a primary filter used to filter dust particles than 5μm. There are primary filter plate, folding, bag three styles, frame materials, paper box, aluminum frame, galvanized iron frame, woven filter material, nylon mesh, activated carbon filter, metal mesh, etc., protection spray wire mesh with double-sided and double-sided galvanized wire. Primary Filter Features: inexpensive, light weight, good versatility, compact structure. Mainly used: central air conditioning and ventilation system pre-filter, a large air compressor pre-filter, clean return air system, efficient filtering device local pre-filter, high temperature air filters, with a stainless steel frame, high temperature 250-300 ℃ filtration efficiency. This efficiency filters, air conditioning and ventilation systems commonly used in a primary filter, also applies to just a simple filter conditioning and ventilation systems. G Series coarse air filter in eight varieties, namely: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature coarse filter). Primary filter paper frame structure of the filter frame is sturdy waterproof plates for fixing the folded filter completed. Diagonal on the frame designed to provide large filter area, and to closely adhere to the filter inside the outer frame. Around the filter professional tailor special bonding adhesive glue and frame, to prevent air leakage or damage caused due to the drag pressure to happen. Disposable paper filter box frame is generally divided into general and high-strength cardboard boxes cardboard cut touch, filter fiber filter material is pleated lined one side metal mesh. Appearance. Rugged and durable. General cardboard frame used to manufacture non-standard specifications of the filter, the filter can be used to produce any size, high strength, not deformed. High-strength touch and standard cardboard for manufacturing a filter, is characterized by high precision specifications, appearance and low cost. If imports or synthetic fiber filter material surface, then its performance can meet or exceed the inlet filter with production. Filter material is folded into the form of high-intensity touch and cardboard, the frontal area increases. Air flow into the dust particles are effectively block the filter material between the pleats and the pleats. Clean air from the other side of the uniform flow, air flow through the filter is so smooth and uniform. Depending on the type of filter material, they block a particle diameter 0. 5μm to 5μm and different, filtration efficiency
