In the ventilation system, the Primary Air Filter plays a vital role. Its influence on air flow and its compatibility with the ventilation system are directly related to the operation effect of the entire system.
From the perspective of air flow, the Primary Air Filter will hinder the circulation of air to a certain extent. When air passes through the filter screen, the air flow rate will decrease due to the pore structure and resistance of the filter screen. If the air resistance of the filter is too large, the air flow in the ventilation system will be significantly reduced. For example, in some improperly designed filters, too fine filter screens or unreasonable filter material stacking methods may cause the air to overcome greater resistance when passing through, just like water flowing through narrow and tortuous channels. This will not only affect the ventilation volume, but also increase the load of equipment such as fans in the ventilation system. Long-term high load state may shorten the life of the equipment.
In terms of compatibility with the ventilation system, the design air volume of the ventilation system should be considered first. The air flow parameters of the Primary Air Filter need to match the rated air volume of the ventilation system. If the rated air flow of the filter is lower than the design air volume of the ventilation system, the ventilation system will not work properly and the expected ventilation effect cannot be achieved. Secondly, the use scenario of the ventilation system is also critical. For places with high air quality requirements such as hospitals and laboratories, the ventilation system may need to find a balance between air flow and filtering effect. At this time, the selection of Primary Air Filter should be able to ensure a certain air flow and effectively filter pollutants. For places with large space ventilation requirements such as industrial plants, the guarantee of air flow is more important. The filter needs to achieve basic filtering functions at a lower resistance to avoid problems such as poor ventilation and stuffiness caused by insufficient air flow.
In addition, factors such as pipeline layout and fan power in the ventilation system will also interact with Primary Air Filter. Reasonable pipeline design can reduce the resistance of air during transportation and work together with the filter to ensure the stability of air flow. The fan power needs to be appropriately adjusted according to the impact of the filter on the air flow to ensure the efficient operation of the entire ventilation system.
