Installation requirements for the high-efficiency filter of the air shower transfer window
The installation position is generally at the top of the air shower transfer window or in the rear blower compartment, located before the blower outlet and the air shower nozzle. → Ensure that the air is filtered first and then blown out from the nozzle.
Sealing requirements (most critical)
The filter must be sealed tightly all around, without any air leakage or gaps.
Common sealing strips / sealing gaskets, pressed tightly without deformation.
Side leakage or bypass flow is strictly prohibited. Otherwise, it is equivalent to no filtration.
The direction must not be installed reversed.
Inlet surface: facing the blower and the duct side
Outlet surface: facing the air shower chamber and the nozzle side
Most filter materials have arrow markings indicating the direction of air flow. The arrow must point downward / towards the outlet.
Installation must be flat and without compression.
The frame must not be distorted, squeezed, stepped on, or pressed and collided with the filter paper.
Ensure that the frame is evenly stressed to avoid cracking and air leakage.
Installation environment requirements
Disassemble and assemble in a clean environment to prevent dust from falling in.
Clean the blower compartment and the interior of the box before installation.
New filters should be installed immediately after unsealing, not placed outdoors.
After installation, verification must be conducted.
Close the door, start the air shower, and check the pressure gauge reading is normal.
There should be no whistling or abnormal air leakage noise.
If conditions permit, leak detection can be performed.
