The main causes of nozzle blockage in the air shower room
1. Failure of the front-end filter (the most common)
The primary filter is not cleaned or replaced for a long time, and dust and debris directly enter the air duct
The high-efficiency filter is damaged or leaks, and small particles penetrate and enter the nozzle
The filter installation is not tight, and there is bypass leakage, with dust taking the shortcut
2. Dust brought in by the environment and materials (source problem)
The goods / packaging carry a large amount of fibers, paper debris, dust, and hairs into the air shower
The workshop has a lot of dust and the environment is dirty, making the air shower a “dust collector”
The materials have powder, debris, plastic fringes, which are blown into the nozzle by the wind
3. Accumulated dust and debris inside the air duct
The air duct and static pressure box of the air shower room have not been cleaned for a long time, and the accumulated dust is blown into the nozzle
The insulation cotton and sealant in the air duct age and fall off, leaving debris that blocks the nozzle
The fan impeller accumulates large pieces of dust and falls off, directly blocking the nozzle
4. Leftover debris from installation / maintenance
Screws, gaskets, glue blocks, and foam left in the air duct during installation
Debris from maintenance is not cleaned up and is blown into the nozzle by the airflow and gets stuck
5. Structural and usage problems of the nozzle
The nozzle has a small diameter, and even a little bit of fibrous debris will block it
The nozzle orientation is unreasonable, and it is prone to facing the dust
Long-term lack of inspection, small blockages turn into complete blockages
6. Moisture and condensation causing adhesion and blockage
The workshop has high humidity, and the dust in the air duct gets wet and forms lumps
Dust sticks to the inner wall of the nozzle, accumulates thicker and thicker, and eventually blocks it
