What air filters are commonly used in HVAC ventilation systems?
HVAC also called air conditioning duct ventilation. In some large buildings, there will be these ventilation systems, such as underground parking lots, commercial buildings and so on.
These ventilation ducts require the use of air filters to purify the air and prevent these ducts from being subjected to dust accumulation of tube. At the same time, it is also necessary to ensure the air quality of the shopping mall.
Most of the air filters used in ventilation systems, which require effective filtration of PM2.5 in the air, with an efficiency of at least 80%. This can ensure that the air entering the ventilation system is qualified and harmless to the human body.
For many commercial ventilation systems, not only the dust in the air needs to be filtered, but also the air filter needs to filter the odor, so in many cases, activated carbon and air filter can be used as a 2-in-1 design.
MORE AIRFLOW RATE
For the public system of some commercial buildings, because of the large inner space and lots of crowded people, it is necessary to keep the air clean at all times, which requires more air change, needs more fresh air enters the ventilation system. So, the air filters should provide larger airflow rate, we recommend using some pocket filter or V bank design filters.
SOME OF THE COMMON AIR FILTERS FOR HVAC
With large dust holding ability, for heavy-duty ventialtion system, remove fine particles efficiency F6 F7 F8.
Pleated pre air filter G4 efficiency made of paper frame or metal frame, for heavy duty ventilation primary filtration.
V bank air filter efficiency F8 F9 H10, final stage of fine filtration for ventilation system.
