The Air Filters In HVAC System
The HVAC system software air filter refers to the gas cleaning equipment used in the HVAC system software. The air filter is used to filter solid, suspended solids or harmful substances such as smoke and particles in the air. It is a key component of the HVAC system software. It filters the raw materials according to the porous structure to purify the indoor air to ensure the gas cleanliness level, so that the natural environment can meet the requirements of industrial production or commercial housing to a large extent.
According to the filtration efficiency and filter type, HVAC air filters can be divided into three categories:
According to the role and efficacy, the general universal air filter can be divided into primary efficiency filter, medium efficiency filter and sub-high efficiency filter. Among them, the primary filter is mainly suitable for the primary and intermediate filters of commercial or industrial ventilation and air-conditioning engineering system software or the pre-filter of the ventilation and air-conditioning engineering system software for clean rooms, which can filter floating dust particles with a particle size of more than 5μm.
Medium-efficiency filter filters are mainly used in the primary filtration of air conditioning units. They can filter floating dust particles with a particle size of more than 1μm. As a front-end development filter to maintain the next level of filter to reduce the load of the latter and increase its service life.
The sub-high efficiency filter can be used as the terminal equipment of the clean natural ventilation air-conditioning unit, and can also be used as the middle filter of the exhaust system in the high-cleanliness site.
HEPA filter: HEPA (High Efficiency Particulate air Filter) filter, which is a high-efficiency air purifier, is a double-layer cleaning technology that can filter 99.97% of floating dust particles with a particle size exceeding 0.3μm. It has a very good filtering effect. Good, excellent sealing performance, long service life, widely used in semiconductor equipment processing plants, LCD screen hardware factories, modular design clean rooms and other places that require extremely high cleanliness levels.
