What is the replacement cycle for medium effect filters?

How long is the replacement cycle of medium effect air filter?

Nowadays, with the development of industrialization and the continuous progress of science and technology, while bringing us prosperity, they also bring pollutants, the air quality becomes worse, the particles in the air become larger, and the impurities in the water are more. At this time, you need a filter. There is a water purifier to filter water quality, and the air is mostly applied to air conditioning. When we install air conditioning, there is not a square box? In fact, it is a filter. Most air conditioners use medium effect filters. Let's take a look at the replacement cycle of medium effect filter and the matters needing attention when replacing it.

I. Replacement cycle of medium effect filter

The filter material of medium effect filter generally has three kinds, composite non-woven fabric, synthetic fiber and glass fiber.

In the rated air volume under the condition of use, 3-4 months need to replace the filter;

Or when the resistance of the filter reaches more than 400Pa, the filter must be replaced;

If the filter is used to clean the filter material, the replacement of the filter material, can be washed with water or containing neutral detergent solution, cool dry, and then change; Allow cleaning twice, that is, to replace the new filter;

If the dust concentration in the use environment is large, the service life cycle will also be reduced.

Two, the replacement of medium effect filter matters needing attention:

Regularly check whether the filter inlet surface is blocked by debris, whether the filter material surface is damaged; If there are items blocking the surface, it should be removed; Filter material surface damage is serious, it is necessary to replace the new filter material or replace the new filter installation; When the filter is installed, it is necessary to ensure that the tightness between the blank holder and the frame is good to prevent air leakage; Do not use heavy objects to impact the surface of the filter, do not force to pull the filter surface of the filter material; When installing the filter bag, ensure that the length of the filter mouth is perpendicular to the ground to ensure the filtering effect of the air supply and prolong the service life.

Summary: Nowadays, there are two types of medium effect filters, which are bagged filters and non-bagged filters. Medium efficiency filters are also used in biopharmaceutical, electronic and petrochemical light industry air filtration.
