Filter products Many people will encounter various problems when purchasing or using high-efficiency filters. Some people will ask what is the actual size and nominal size of a high-efficiency filter called a clapboard?

The difference between the actual size of the high efficiency filter and the nominal size:

1. Why there is a distinction between actual size and nominal size of high-efficiency filters with or without clapboards, because the nominal size is a filter including the outer frame and filter material, while the actual size generally excludes the outer frame, and only calculates the width of the filter material. Height, depth and area of filter material.

2. When calculating the air volume of the filter, it must be calculated according to the actual size. For example: when calculating the wind speed of a 610*610*69mm aluminum alloy frame filter without partitions, the nominal size minus the size of the left and right outer frames is equal to the actual size: (0.610 -(0.018*2))*(0.610-(0.018*2))*3600*surface wind speed (M/S)=air volume m³/H.

3. Use the nominal size (that is, the frame size) uniformly in production and ordering, otherwise errors will easily occur.

High-efficiency filters can be divided into: high-efficiency with partitions and high-efficiency without partitions. The high-efficiency filter with clapboard is made of ultra-fine glass fiber as the filter material, glued paper, aluminum platinum as the partition plate, and glued with the wooden frame or aluminum alloy frame. It has high filtration efficiency, low resistance, and large air volume. Advantages, widely used in various local purification equipment and clean workshops.

The installation of high-efficiency filters is the key to purifying air-conditioning systems and clean room construction and installation. The following points should be noted:

Clean before installation;

The system should be blown clean;

The purification workshop should be fully cleaned again. If a vacuum cleaner is used for vacuuming, ordinary vacuum cleaners are not allowed, and vacuum cleaners equipped with ultra-clean filter bags must be used;

If it is installed in the ceiling, the ceiling should be cleaned;

Then clean the clean room again after the trial run system for 12 hours before installing the high-efficiency filter.
