1. Introduction

Each High efficiency Particulate Air filter(HEPA filter) is tested by flame method, which has the characteristics of high filtration efficiency, low resistance and large dust capacity. The high efficiency air filter can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverage food, PCB printing and other industries dust-free purification workshop air-conditioning terminal air supply. High efficiency and ultra-high efficiency filters are used in the end of clean room, which can be divided into: partition high efficiency filter, no partition high efficiency filter, large air volume high efficiency filter, ultra-high efficiency filter and so on.

a、characteristic

The high-efficiency/ultra-high-efficiency separator filter adopts a separator-type design, and the corrugated separator can accurately maintain the distance between the pleats, and maximize the use of the filter material with the least resistance. 180 pleats on both sides of the filter material are folded into a wedge-shaped pleat layer. When the filter material is bent, there are two indentations to make it form a wedge-shaped box pleated layer at the end of the partition. The wedge-shaped box pleated layer can be Prevent damage to the filter material.

b、usage

HEPA filter is mainly suitable for terminal filtration of various special clean rooms and various local purification equipment, such as clean bench laminar flow hood and other environmental air purification;
