Primary paper frame filter
The outer frame of the initial effect paper frame filter is generally divided into a general hard paper frame and a high-strength die cut hard cardboard. The filter element is made of pleated fiber filter material lined with single-sided metal wire mesh. Beautiful appearance. The general cardboard frame is used to manufacture non-standard filters and can be used for the production of filters of any size. It has high strength and is not easily deformed. The general cardboard frame is used to manufacture non-standard filters and can be used for the production of filters of any size. It has high strength and is not easily deformed. High strength die cut cardboard is used to manufacture standard specification filters, characterized by high specification accuracy, low aesthetic cost. If imported face fiber or synthetic fiber filter materials are used, their various performance indicators can reach or exceed those of imported filters.
The outer frame of the primary effect 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 wire mesh. The appearance is beautiful. The structure is sturdy and durable. General cardboard frame is used for manufacturing non-standard specifications of the filter, can be used for any specifications of the filter production, high strength, not easy to deform. High-strength die-cut cardboard is used for manufacturing standard specification filters, characterized by high specification accuracy and low cost of aesthetics. If imported face fiber or synthetic fiber filter material is used, all its performance indexes can reach or exceed those of imported filters.
