Air filter(Air Filter) is usually refers to the air filter device, in most cases clean workshop, clean workshop, laboratory and clean room are required to be equipped with air filter, sometimes electronic machinery and communication equipment such as dust also need air filter. At present, air filters have primary effect filters, medium effect filters, high efficiency filters and sub-high efficiency models. Of course, various models have different standards and use efficiency.
As the treated compressed air from the gas source contains a variety of impurities, usually water vapor and oil droplets, and some solid impurities, such as rust, sand, pipe sealants, etc., these impurities accumulate for a long time. It will damage the piston sealing ring and block the small exhaust holes on the components, which will shorten the service life of the components or fail for a long time. At this time, the role of the air filter is highlighted. The air filter is used to effectively separate the liquid water and liquid oil droplets in the compressed air, and it can filter out the dust and solid impurities in the air, but it also has a disadvantage. It cannot remove gaseous water and oil.
First effectAir filterIt is used to remove dust particles ≥ 5μm. Its initial resistance is ≤ 50Pa. The primary air filter can play the role of pre-filter protection in the air conditioning purification system. Of course, it can also protect the air conditioning. Other accessories in the box will effectively extend their service life.
The medium effect filter is used to remove dust particles ≥ 1.0μm. Its initial resistance is ≤ 80Pa. The medium effect filter acts as an intermediate filter in the air conditioning purification system, which can fully reduce the load of the high efficiency filter and effectively extend the service life of all accessories in the high efficiency and air conditioning box.
The sub-high efficiency filter is used to remove dust particles ≥ 0.5μm, and its initial resistance ≤ 120Pa. The sub-high efficiency filter plays the role of an intermediate filter in the air conditioning purification system, so it usually plays the role of a terminal filter in the low-level purification system.
The high efficiency filter is used to remove dust particles ≥ 0.3 μm, its initial resistance ≤ 220Pa, and the high efficiency filter is used as a terminal filter in the air conditioning purification system.
