HEPA filters for Hospital
The air always contains some bacteria and viruses, pathogene, dust and so on, that will make patient wound be infected. To control those resources, we need create a super clean area before doing a surgery.
The best solution is HEPA filters, HEPA filters can remove 0.3um particles, bacteria, virus, and other pollution with good efficiency of 99.995% to 99.999%, under the airflow filtered by HEPA, the air cleanliness level is at least class 100. It`s a wonderful place to do a surgery.
The standard surgery clean space size is 3*3m, HEPA filters be installed on the ceiling top, air flow vertical from upon to down, 3*3m space is quite enough to create a place for patient and medical care personnel.
To maximize the HEPA filters life span, we can add pre filters and pocket filter at the HVAC tunnel, pocket filters can remove 0.5um particles with good efficiency of 95%, that will release the burden of HEPA.
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;
