Nov 05, 2019

The primary and secondary effect filters are mainly: flat filter, folding filter, nylon mesh filter, metal mesh filter, high temperature filter, activated carbon filter, bag filter, washable filter, box filter And so on. Below is a northern filter to explain the primary and secondary air filter and cleaning process suitable for cleaning:


General air filters, primary filters and medium efficiency filters are the easiest to clean. Only the high efficiency filters we are familiar with can't be cleaned. The initial and medium efficiency filters are plate type, folding type and bag type. Style, the outer frame material is paper frame, aluminum frame, galvanized iron frame, filter material is non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc. The protective net has double-sided sprayed iron wire mesh and double-sided galvanized wire mesh. The junior high efficiency filter is suitable for primary filtration of air conditioning systems.

The preliminary air effect air filter cleaning process is as follows:

1, the initial effect filter, the replacement of the medium efficiency filter must meet the basic requirements of the production process conditions for the production of air conditioning systems, while achieving the necessary production conditions.

2. Each time the primary filter is cleaned, the primary filter must be completely poured down (replace the water directly on the frame for cleaning), placed in a special cleaning room, repeatedly cleaned with clean water (tap water), and the filter is inspected for damage. If there is damage and timely replacement (do not use high temperature water, high pressure water during cleaning), when the filter is cleaned thoroughly, the relatively sealed room should be placed in a dry place. After the filter screen is dry, the staff will check the filter one by one. Can be installed and used after inspection

3. When the filter is removed and cleaned, the staff should clean the inside of the air-conditioner cabinet repeatedly with water. The removable and washable parts should be removed and cleaned, the surface of the equipment should be cleaned, and finally wiped with a dry cloth (cloth can not be shed) Once again, the primary filter can be installed until the cabinet meets the dust-free requirements.

4, each time you replace, clean the initial effect filter, the chassis should fill in the detailed work record in time, and prepare for review.
