Anhui efficiency filter manufacturers, Anhui efficiency filter Price

HEPA filter can be used in optical electronics, LCD liquid crystal manufacturing, biotechnology, precision instruments, beverages and foodstuffs, PCB printing industry clean purification plant at the air terminal air. Efficient and ultra-high efficiency filters are used in clean room end, its structure can be divided into: HEPA, no partition efficient, high winds and high efficiency, ultra-high efficiency filters. Choice points 1. HEPA filter optional main control parameters filtration efficiency, rated air flow, initial resistance under nominal amount of wind, dust holding capacity and so on. 2. Press the GB / T6165-1985 method "high efficiency particulate air filter performance test methods transmittance and resistance" required inspection, transmittance ≤0.1% (ie efficiency ≥99.9%) or fine particles having a particle diameter ≥0.1μm Count permeability ≤0.001% (ie efficiency ≥99.999%) of filters for HEPA filter. 3. HEPA filter media used ultra-fine glass fiber. The air filter should meet fire safety requirements, high efficiency air filters by refractory were divided into three levels: a filter, filter all materials are non-flammable, non-flammable material shall conform to GB8624-1997 A class. Two filters, filter media should be in line with non-combustible material GB8624-1997 A class, dividing panels, frames can be used in line with GB8624-1997 B2 level of combustible materials. 3 filters, filter all the materials available in line with GB8624-1997 B3 grade 5 design, according to the initial resistance twice as the final resistance, resistance as a filter calculation. First 6 HEPA filter resistance must not exceed 10% of the product sample resistance. 7 HEPA filter should not be used alone, high efficiency air filter should be set at the end of the air conditioning system. 8 The manufacturer shall provide dust holding capacity. High efficiency filter factory should leak. Other requirements set according to user needs. 9 In the general non-parallel flow clean air conditioning system in the use of the combination of the filter outlet. Categories are divided into: HEPA filters, no partition efficient filters, V-BED highly efficient filter, high temperature high efficiency filter.
