1. The outer frame of the primary effect filter is an aluminium alloy frame which can be disassembled. It is strong, durable and easy to deform.
2. Easy to install and disassemble, high-quality cleaning filter material, low resistance, high dust-holding rate, long service life.
3. The protective rib of the filter is strengthened, and the firmness of the filter is increased. The filtration efficiency of the primary filter with conventional thickness of 21 mm, 25 mm, 46 mm and 95 mm is 40%~60% for particles (> 5.0 um). The special chemical fiber cloth with high flux and low resistance is used as filter material. The dust volume is large, such as paper, galvanized steel plate, aluminium alloy or plastic. The outer frame of the air filter is mainly used as the pre-filtration and room of the high efficiency filter. Purification and filtration of ventilation system.
Efficiency level of primary filter: G2, G3, G4
1. Small resistance and large air volume; so_0_f_2
2. Long service life;
3. It is widely used in primary filtration of air conditioning system.
Initial filters are used in office buildings, conference rooms, hospitals, shopping malls, gymnasiums, airports and other large civil building ventilation and air-conditioning systems. /
