The maintenance method of G4 grade medium effect cotton board filter mainly includes the following aspects:
First, regular replacement
Replacement cycle: the replacement cycle of G4 grade medium effect cotton board filter is generally 3 to 6 months, but the specific replacement time needs to be adjusted according to the use of the environment, use frequency and air quality and other factors. If the dust concentration in the environment is large, or the filter dust is serious, it may need to be replaced in advance.
Replacement standard: when the filter resistance reaches twice the initial resistance, or the filter surface appears serious damage, deformation and other conditions, should be replaced in time new filter.
Second, regular cleaning
Cleaning frequency: For washable G4 medium effect cotton board filters, it is recommended to clean once a quarter. If the use of the environment is harsh, you can appropriately increase the frequency of cleaning.
Cleaning method:
Vacuum cleaning: Use the soft brush head of the vacuum cleaner to gently wipe the surface of the filter to remove dust.
Wash: Put the filter in clean water, gently rub and rinse repeatedly until the water is clear. Care should be taken to avoid the use of brushes or high-pressure water gun spray, so as not to damage the filter.
Drying: the cleaned filter should be dried flat in the clean area to avoid exposure to the sun or drying, so as not to affect the performance and life of the filter.
Three, correct installation
Installation direction: ensure that the installation direction of the filter is correct, consistent with the direction of air flow, to avoid air leakage or affect the filtration effect.
Sealing: when the filter is installed, it should be guaranteed that it is well sealed with the pressure edge of the frame to prevent air leakage.
Installation location: The filter should be installed in a well-ventilated position, easy to maintain and replace.
Fourth, avoid moisture and corrosion
Storage environment: The filter should be stored in a dry and ventilated environment to avoid moisture and corrosion.
Use environment: In the process of use, should avoid contact with corrosive substances, so as not to damage the filter.
5. Regular examination and monitoring
Check the appearance: check the appearance of the filter regularly, if there is damage, deformation, etc., should be replaced or repaired in time.
Monitor the pressure difference: if there is a pressure difference meter or pressure difference sensor before and after the filter, the pressure difference value should be monitored regularly. When the pressure difference exceeds the specified range, the new filter should be replaced in time.
Vi. Other matters needing attention
Avoid impact: do not use heavy objects to impact the surface of the filter, so as not to damage the filter.
Special purpose: the workshop of the primary and intermediate filter should be special, not interchangeably used. At the same time, it should be washed, dried and stored separately.
Timely replacement: when the clean primary and medium effect filter is installed, its initial pressure difference is less than the original initial pressure difference of the filter, the filter bag can not continue to use, should be eliminated.
Through the above maintenance methods, the service life of G4 grade medium effect cotton board filter can be extended to ensure its filtration effect and provide guarantee for indoor air quality.
