Structure of primary filter
Structure of primary filterThe outer frame of the filter is made of sturdy flashing to hold the folded filter media in place. The diagonal design of the outer frame provides a large filtering area and allows the inner filter media to be tightly adhered to the outer frame. All sides of the filter are bonded to the outer frame with special professional adhesive, which can avoid air leakage or breakage due to wind resistance pressure.The outer frame of the disposable paper frame filter is generally divided into general hard paper frame and high-strength die-cut cardboard, and the filter element is pleated fiber filtration material lined with single-sided metal wire mesh. Beautiful appearance. The structure is sturdy and durable. General cardboard frame for the production of non-standard standard filters can be used for arbitrary standard filter production, is high strength, not easy to deform. High-strength die-cut cardboard is used to produce standard filters, featuring high standard precision and low cost. If imported face fiber or synthetic fiber filter material is used, all its performance indexes can reach or exceed the imported filters. |
