Cardboard Pleated Pre Filter
Construction
It is made of moisture-resistant cardboard as the outer frame, and the interior is filled with non-woven fabrics or glass fibers and other filter materials, which increase the windward area by folding, thereby improving the filtration efficiency. The frame material can be cardboard, aluminum frame, galvanized plate frame or stainless steel frame; the specific choice depends on the requirements of the use environment. In terms of filter materials, high-quality synthetic fibers (such as polyester fibers) are a common choice, and their fluffy and dense fiber structure can effectively intercept airborne particles
