Many times we may know the use of the air filter is very extensive, the effect is very good, but it should be noted that the problem for the time of their choice and to know how much about it Today efficiency air f iltration equipment selection points as an example, and we take a detailed analysis of it!polyester sewing thread General ventilation air filter performance test methods in accordance with the our domestic JG/T22-1999 "provides for the atmospheric dust particle size ≥ 1.0μm particles counting efficiency ≥ 20% and <70% of the filter is in effect air filters, can also be directly referred to as filter efficiency, or an air filter for the unification. In general, the initial resistance of the efficiency air filter should be ≤ 80Pa calculated design, we can follow the initial resistance twice as final resistance. Efficiency filter performance, we look at its select elements of it! First, the choice of medium efficiency air filter reference to the rated air flow control parameters, filtration efficiency, initial resistance, dust holding capacity and Dimensions numerous factors. Second, should be in accordance with the predetermined method of JG/T22-1999 "general ventilation air filter performance test method" apparatus. Third, this equipment commonly used in the filter glass fibers, non-woven fabrics, etc. can be selected. Production manufacturers should provide data of filter dust holding capacity. The initial resistance of the device should be ≤ 80Pa design can follow the end of the initial resistance twice as resistance, as the resistance value of the filter calculation.
