Where are the primary filters mainly used?
The primary filter is mainly used to filter dust above 5um, and it is used in the pre-filtration of air conditioning and ventilation systems to avoid dust pollution inside the system; at the same time, the primary filter is used for pre-filtration of large air compressors, centralized ventilation and air conditioning systems in clean rooms and return air. Filtering to prolong the service life of the high-efficiency filter in the latter stage; in fact, the primary-efficiency filter is also used in the ventilation system of ordinary industrial plants to meet the general cleanliness requirements of the air.
Primary filter is divided into primary plate filter, primary pleated filter, primary paper frame filter, primary nylon mesh filter and primary bag filter. As the pre-filter of the air filter, they can effectively block the dust particles in the air, protect the medium-efficiency and high-efficiency filters at the back end, and the service life of good quality primary filters under normal environmental conditions is 3- 6 pieces should be replaced once to avoid the impact of the blockage of the filter surface on the air quality. You should still pay attention to the replacement cycle.
