Replacement period:

Under the condition of rated air volume, the gas filter element for natural gas needs to be replaced every 3-4 months; or when the 

resistance of the filter reaches more than 400Pa, the filter must be replaced; if the filter uses washable filter material, then The replaced filter 

material can be rinsed with water or a solution containing neutral detergent, dried, and then replaced; it is allowed to wash twice at most, that 

is, a new filter must be replaced; if the dust concentration in the use environment is high , then this service life cycle will also be reduced.

Precautions for use:

Regularly check whether the air inlet surface of the filter is blocked by debris and whether the surface of the filter material is damaged;

If there is any object blocking the surface, it should be removed; if the surface of the filter material is seriously damaged, it must be replaced

 with a new filter material or a new one. Reinstall the filter; when installing the filter, ensure that the sealing edge with the frame is well sealed to 

prevent air leakage; do not use heavy objects to hit the surface of the filter, and do not use force to pull the surface of the filter material ; When 

installing, the length direction of the filter bag mouth should be perpendicular to the ground to ensure the filtering effect of the air supply and increase the service life.

Application fields:

It is mostly used in central air-conditioning and centralized ventilation systems.

The filter material of this structure is made of multi-bag type, which increases the area of filter material and air supply volume, and reduces the resistance 

of air supply; it has the advantages of compact structure, large air supply volume, strong versatility, and convenient installation.
