Characteristics and uses of primary air filters

Air filters are divided into four types: primary, intermediate, sub-high efficiency, high efficiency, according to the air volume of the large and small in a pipeline to install a different number of air filters, filtration section installed in the centralized air conditioning system, to send into the indoor air dust particles filtered out. To achieve high quality of indoor air.

Characteristics of primary air filters:

1, the filter media in the equipment is 100% synthetic fiber, with an average efficiency of about 30% to 35%;.

2. The filter material will be metal mesh bonded to the outlet end to prevent vibration.

3. The outer frame of the filter is made of sturdy, moisture-proof cardboard frame to ensure that it will not be deformed, ruptured or twisted.

4. The filtering part is made of folded filter material, which increases the area of filtration and reduces the resistance of the filter.

Usage of primary air filters:

1. Fresh air units and ventilation systems for central air conditioning; and

2. Special constant temperature and humidity air-conditioning units for programmed control switches and computer rooms; and

3, Paint spraying system, paint shop pre-filtration air compressor and gas turbine pre-filtration system.

4. Pre-filtration system for high efficiency filters.

5, office buildings, shopping malls, hospitals, airports and general industrial plants or clean rooms and other places within the centralized ventilation system pre-filtration.
