Details
Features:
1. It is made of polyester, polyamide, nylon and other chemical synthetic fibers. According to the thickness of the fiber line diameter and density, it is made by non-woven, multi-directional and gradient needle rolling method. It has the characteristics of high breathability, low pressure loss and high dust collection.
2. It is made of composite fibers with different internal and external melting points. The contacts between the fibers are strong, tightly bonded and not easy to fall off.
3. No chemical adhesives are added. Coarse fine fibers are mixed together with hot melt fibers. It is not easy to flame in case of fire, and the flame retardant point complies with the German industrial standard DIN53438F1.
4. Washable and reusable
5. Galvanized steel plate frame or aluminum alloy frame can be installed, and metal back mesh can be installed, which can effectively support the filter to withstand high air volume and is not easy to deform.
Purpose:
It is suitable for electronics, pharmaceutical, food and other industries, prevention and control of pollution, fresh air filtration, pre-filtration of medium-efficiency filtration and air conditioning system return filtration.
