1, the installer’s sense of responsibility is not strong, resulting in improper installation.
2, high efficiency filter itself leaks, defects factory. A) lax inspection b) poor quality filter c) improper transportation d) filter and frame
Connection is not tight.
3, static pressure box quality reasons:
1) conventional static pressure box
Features:
(1) material selection 1.0 nmm galvanized sheet, the material is too thin and efficient filter is not easy to force when connected, easy to deformation.
(2) static pressure box edge after bending through the welding and static pressure box
Connection, due to welding easy to cause distortion and uneven frame easily lead to leaks.
(3) high-performance air filter and the pressure tank connection required with four compression, respectively, high efficiency filter 4 corners and static pressure box to suppress pressure on the filter pressure uneven, so the connection is not sealed .
2) new static pressure box
Features:
(1) material for 1.5 mm hot-dip galvanized sheet, because the material is thicker than the conventional static pressure box, and the high-efficiency filter is connected after the force will not be deformed.
(2) static pressure box and pressure side by punching a one-time non-welding forming stamping, sealing performance.
(3) As the static pressure box equipped with a pressure ring, so that when the high efficiency filter connected by the pressure ring pressed around, so the force evenly, the connection is better sealed.
(4) static pressure box pressure side of the structural transformation, an increase of support efforts, and high efficiency filter connection, you can not force deformation.
