Introduction to the characteristics and uses of primary air filters

Characteristics of primary air filters:

1、Using ultra-fine synthetic fiber made of special weaving method, avoiding the old glass fiber material may cause discomfort to the human body.

2, the filter material contains electrostatic fiber, the sub-micron (size 1μ or less than 1micron) dust filtration efficiency is particularly good, with high dust trapping power, high dust load and high permeability. High service life.

3. Each filter bag is fixed with a metal strip to increase the strength of the filter and prevent the filter bag from rupturing due to the friction of the wind cut when the wind speed is high.

4, each filter bag has six partitions evenly divided in the bag width to prevent the filter bag from over-expansion with the wind pressure, covering each other and reducing the effective filtration area and efficiency.

5、Each bag edge is fused by ultrasonic wave, which has good airtightness and bonding strength and does not produce air leakage or rupture.

Matching outer frame:

6, galvanized frame (optional outer frame thickness: 20mm, 25mm)

7, aluminum alloy (optional frame thickness: 20mm, 25mm, 45mm)

8. Plastic frame (optional outer frame thickness: 25mm)

Usage of primary air filters:

1、Precision Clean Room Clean Room of the second level of filtration.

2、High efficiency filters are pre-filtered.
