HEPA filters and Air Filters for HVAC system
Health of people inside the commercial building is relatively to the in door air quality, as there are many pollution of air in our city, the risk of cancer and respiratory disease is risen. For people working in the commercial building, it`s very important to create a good indoor air environment.
We can add pre filters and pocket filters or v bank filters at the HVAC tunnel, the filters can remove PM2.5 and other pollution that harmful to human health. Pre filters can collect large dust and pocket filters can remove 0.5um particles at efficiency of 80-95%;
The commercial building include air port, school, hospital, super market, office building, downtown and so on, to improve the in door air quality, can increase the work efficiency and human inside will have a better mood.
To remove some strange smell in the building, we can add some carbon filters in the HVAC system;
The pre filters can remove large size dust, it`s very useful to enlarge the second filter and HEPA filters service life. The filter media is synthetic and cotton, flat media or pleated media design, the metal mesh on two side to hold the filter media. Efficiency is G3 or G4. Frame is waterproof paper or aluminum alloy or galvanized steel. The paper frame is a economical choice and can be used in dry situation. Pre filters provide large dust holding ability and low resistance.
The V bank filters is mini pleated media design, glass fiber or polyester. It can remove fine dust particles with efficiency about 80*99%. It`s very popular in food and beverage industries. Plastic frame and 2V or 4V construction, 12*24*12 or 24*24*12 inch size. The V bank filters should be replaced every 3 or 6 months. Features, high moist resistance, can replace pocket filters moist environment.
The FFU is a very common equipment for the cleanroom, it normally be installed on the ceiling grid, to make a high cleanliness level room, it`s quite helpful to improve the indoor air quality for all of the high tech industries such as micron-electronics, fine machinery and medicine and so on, food process industries need stainless steel frame due to the high moist environment.
Metal frame, glass fiber media, H13 or H14 efficiency, it`s the final stage for food process industries cleanroom, the aluminum separator can beat high moist environment. Each HEPA filters are tested before shipping. The HEPA filter cassette is the best stable filters, can be used in turbulence airflow and provide long service life.
the mini pleated HEPA filters is a important part in cleanroom HVAC system final filtration, made of waterproof glass fiber media, mini pleated design to maximize the filter area. The filter efficiency of removing particle size 0.3 micron can reach to 99.99% to 99.999% level. Hot melt as the separators and aluminum alloy as the filter frame;
