How should the high-efficiency filters of the goods shower be maintained and replaced?

The maintenance and replacement of high-efficiency filters in the air shower room are crucial for maintaining the purification effect of the air shower room. The following are the specific methods:
Maintenance
Daily inspection
Check the appearance of the high-efficiency filter every day to see if there is any damage, deformation, or excessive dust accumulation. If you find obvious dust on the surface of the filter, you can gently wipe it with a clean cloth, but be careful not to damage the filter.
Check whether the sealing rubber strips of the filter are in good condition and whether there are any problems such as delamination or cracks. Ensure that the filter is well sealed with the installation frame to prevent unfiltered air from leaking into the material shower chamber.
Regular cleaning
The high-efficiency filter is generally cleaned once every 1 to 2 weeks. Use a vacuum cleaner or compressed air to vacuum or blow on the surface of the filter to remove dust and impurities on the surface. When cleaning, start from the upwind side of the filter and proceed evenly in a certain sequence to ensure that the entire surface of the filter is cleaned.
For the filter frame and the surrounding area, it is also necessary to wipe them clean with a damp cloth to prevent dust accumulation.
Replace
Judgment of replacement timing
When the resistance of the high-efficiency filter reaches about twice the initial resistance, the filter should be considered for replacement. The resistance changes of the filter can be monitored through the differential pressure gauge installed in the material shower chamber.
Even if the resistance of the filter does not meet the above standards, it is still recommended to replace it if the usage time exceeds its specified service life (usually 1-2 years, depending on the actual usage conditions and the quality of the filter) to ensure the filtration effect.
If any damage or leakage of the filter is found during the inspection, it should be replaced immediately regardless of the resistance and usage time.
Replacement steps
Before replacement, turn off the power of the goods shower room first and make sure there is no one inside.
Open the filter installation frame of the goods shower room, carefully remove the old filter, and be careful to avoid dust and contaminants on the filter falling off.
Clean the filter installation frame and the surrounding area to ensure no dust or debris is remaining.
Place the new high-efficiency filter in the installation frame in the correct direction, and make sure that the sealing rubber strip of the filter is closely attached to the frame.
After installing the filter, close the installation frame and check whether the filter is firmly installed and whether the seal is good.
Turn on the power of the air shower. After running for some time, check the operation of the filter and its sealing performance again to ensure the normal operation of the air shower.
When maintaining and replacing high-efficiency filters, operators should wear clean work clothes and gloves to avoid secondary pollution to the filters and the material shower chamber. At the same time, high-efficiency filters that are of qualified quality and meet the requirements of the cargo shower room should be selected for replacement.
