How to select high efficiency filter accurately

Based on our understanding of the use of air filters and their related knowledge over the years, considering that there is also a general lack of understanding of the use, replacement and maintenance of air filters by customers, Here are some brief descriptions of the general customer's concerns about the maintenance and replacement cycle during the use of air filters. I hope this will help you in your scientific selection of air filters

For 1000-100 ,000 clean room purification systems, three-level air filtration is usually used, that is, coarse, medium, and efficient air filters; Crude effect and medium effect are generally placed in the air treatment device, and the medium effect air filter is placed in the positive pressure section. The sub-high efficiency or high efficiency filter is generally located at the end of the purified air conditioning system.

Teach you how to select and install high efficiency air filters

High-efficiency air filter refers to the air filter device, which is generally used in clean workshops, clean factories, laboratories and clean operating rooms. Air filters can be divided into primary air filters, medium air filters, high efficiency filters and sub-high efficiency according to their working principles.

1. For small purifying equipment such as clean workbench, wind shower room, layer hood, etc., due to the small amount of wind treatment, the general new wind inlet wind surface adopts coarse filter or medium efficiency filter, and the wind feed end must use high efficiency filter or ultra-high efficiency filter; ...

2. The selection and configuration of air filters in the air purification system are generally rationalized according to the air cleanliness level of the cleaning room and the special requirements of the production process.

A. For a clean room purification system of 1000-100 ,000 grades, three levels of air filtration are usually used, namely, crude, medium and efficient filters; The crude and medium efficiency are generally placed in the air treatment device, and the medium efficiency filter is placed in the positive pressure section. The sub-high efficiency or high efficiency filter is generally located at the end of the purified air conditioning system.

B. For clean air conditioning systems of grades 100 to 1000, crude, medium, sub-high efficiency filters are usually installed in new air treatment units, and high-efficiency filters or ultra-high efficiency filters are also installed in clean room circulation systems; Generally efficient filters are located at the end of the purified air conditioning system, that is, on the roof of the cleaning room; For ultra-efficient filters, they must be located at the end of the purified air conditioning system to ensure the required air cleanliness level requirements.

3. When the air treatment air volume of the entire purification system is known, the number of filters required can be determined based on the rated air volume of the selected filter.

Installation and use of efficient filters

For the selection and configuration of air filters in the air purification system, the selection and configuration are rationalized according to the level of air cleanliness and the special requirements of the production process in the cleaning room.

When the air volume of the entire purification system is treated, the number of filters required can be determined according to the rated air volume of the selected filter, and small purification equipment such as a clean table, a wind shower room, and a layer cover, due to the small amount of air handled., General new wind into the air surface adopt thick filter or medium filter, the end of the wind must choose a high efficiency filter or ultra-high efficiency filter.

Purified air conditioning system, usually set up in the new air treatment device rough, medium, sub-high efficiency filter, in the clean room circulation system, but also set up efficient filter or ultra-efficient filter; Generally efficient filters are located at the end of the purified air conditioning system, that is, on the roof of the cleaning room; For ultra-efficient filters, they must be located at the end of the purified air conditioning system to ensure the required air cleanliness level requirements.

Due to the brittleness of fiberglass paper, the use and installation should first consider non-contact with sharp items and repeated rubbing. Secondly, fiberglass paper should be used with minimal contact with water or other corrosive liquids so as not to affect its normal use.. Require clean plant to have good clean equipment. Thirdly, thick, medium and high efficiency filters are reasonably used to ensure that each filter does not bear an excessive dust load. Finally, the installation of visual inspection before the filter paper and filter appearance is not damaged, and after the installation of the inspection seal, strictly leak detection.
