Cardboard filter

The filter material of the cardboard filter is packed into a high-strength touch and rigid cardboard in a folded form, and the area facing the wind increases. The dust particles in the incoming air are effectively blocked between the pleats and pleats by the filter material. Clean air flows evenly from the other side, so the air flow through the filter is smooth and uniform. Depending on the filter material, the particle size blocked by it varies from 0.5 μm to 5 μm, and the filtration efficiency is also different.
Detailed introduction

The outer frame of the cardboard filter is generally divided into a general cardboard frame and a high-strength die-cut cardboard. The filter element is a pleated fiber filter material lined with a single-sided metal wire mesh. The general cardboard outer frame is used to manufacture non-standard filters, which can be used to produce filters of any specifications. It has high strength and should not be deformed. High-strength felt and cardboard are used to make standard specifications of filters, which are characterized by high specification accuracy and low cost. If the imported surface fiber or synthetic fiber filter material is used, its various performance indicators can reach or exceed the similar products of imported filters.

The filter material of the cardboard filter is packed into a high-strength touch and rigid cardboard in a folded form, and the area facing the wind increases. The dust particles in the incoming air are effectively blocked between the pleats and pleats by the filter material. Clean air flows evenly from the other side, so the air flow through the filter is smooth and uniform. Depending on the filter material, the particle size blocked by it varies from 0.5 μm to 5 μm, and the filtration efficiency is also different.

     Cardboard filter material is made of non-woven fabric, fluffy fiberglass felt, plastic mesh or metal mesh. The most commonly used are non-woven fabrics and glass fibers. The efficiency can reach the primary or intermediate effect.
