Replacement period:

Under the condition of rated air volume, the special 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 clogging 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.

Technical Parameters

The outer frame is: galvanized sheet, aluminum profile, 304, 316;

The filter material is: filter cotton

Temperature: -10~~80℃,

Humidity: 80%

Application field

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

Features:

It is mainly used as the post-filter of the general air-conditioning system and the pre-filter of the purification air-conditioning system to filter the 1um particle dust in the atmosphere. Its filtration efficiency is 50%~~99%..

The outer frame is: galvanized sheet, aluminum profile;

The filter material is: filter cotton

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.
