Foldway Paper Frame Filter Mesh
Foldway Paper Frame Filter Mesh also called primary effect paper frame filter, disposable filter, cardboard filter, HVAC Filter, MERV 11 Filter, which mainly filters 5-10um dust particles in the air. The outer frame is made of a hard paper frame, and the non-woven chemical fiber cloth is folded and formed with a metal mesh support, which is more stable. Beautiful appearance. Sturdy and durable construction.
It can be used with paint arrestor filter pre-filter, ceiling filter, paint stop filter, paint filter paper, sepa paint, HVAC filter, rigid box filter, exhaust filter, non-woven, high temperature resistance filter, plank filter, pleated filter, auto filter, Pocket Filter, disposable filter, ULPA filter& HEPA Filter , Activated Carbon Filter, face mask, mesh filter, paper filter, V cell filter, FFU, HEPA filter and other products.
The paper frame primary filter is mainly suitable for filtering particles with a diameter of 5pm. The filter material is made of domestic high-quality non-woven fabric, glass fiber and synthetic fiber through special blending or imported polyester fiber. Balanced spacing and double reinforcing rib design ensure equal-height pleats of the filter, so that the filter can achieve a large dust holding capacity when the resistance is small.
The outer frame of the disposable paper frame filter is generally divided into general cardboard frame and high-strength cardboard. The filter element is a pleated Xiaowei filter material lined with a single-sided wire mesh. Beautiful appearance, strong and durable structure. Generally, the 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 suitable for deformation. High-strength die cardboard is used to manufacture filters of standard specifications, which are characterized by high specification accuracy, beautiful appearance and low cost
The filter material is packed into high-strength die cardboard in a folded form, and the windward area is increased. Dust particles in the inflowing air are effectively blocked by the filter material between pleats and pleats. Clean air flows out evenly from the other side, so the airflow through the filter is smooth and even. Depending on the filter material, the particle size it blocks varies from 0.5μm to 5μm, and the filtration efficiency is also different.
