the pocket filter with very good dust-holding ability, it is the second filtration of an air handling unit. the multi-pocket design helps enlarge the airflow rate and reduce pressure drop.

According to different airflow and efficiency requirements, offers pocket quantities from 2 to 10 units, pocket lengths vary from 200mm to 1000mm and customized sizes are available.

Application
For most commercial buildings and cleanroom HVAC systems, remove dust size over 5micron.

Typical Application

The Pocket filters have a great ability to remove dust and even odor, also they are quite economical compared with some other designs, almost every air handling unit and HVAC need this design filter. Most of the ventilation systems of commercial buildings and air conditioning systems, etc.

Final stages

The final stage is for some commercial buildings such as airports, libraries, schools, malls, and subway stations.

Second stages

the second stage is for some applications that need to remove 0.3-micron size particles such as hospitals, laboratories, pharmaceuticals, and micron-electric factories, the purpose of the pocket filter is to remove large size particles.

For dried situation

It is cheaper in price, convenient to install, long service life, and has an excellent dust removal effect. the pocket filter is not suitable for humidity situations. If the environment is humid, we recommend using a V bank filter instead. The HVAC pocket air filter also can play a role to act as the pre-filter for the HEPA filter to help remove particles above 5 microns and extend the life of the HEPA filter.

Excellent dust removal effect

AHU pocket filter has an excellent dust removal effect and can collect dust well. Its main function is to remove particles larger than 5 microns, and its highest efficiency can reach as much as 95%. With a multi-bag design, each pocket can collect dust individually.

V-shaped pockets make more air filter area. Usually offering 4V, 5V, 6V, 7V, 8V or even 10V design, more V can provide more dust holding capacity. And longer pocket can additionally increase the dust-holding capacity.

During the installation process, the bag must be in a vertical position stand, and cannot be placed horizontally. Because horizontal placement can cause the pocket to collapse, which is not conducive to airflow.

If the pocket is too long, can add a handle at the end of the bag and tie the handle to the outer box of the filter to maintain its shape.

Synthetic and fiberglass filter media

Synthetic and fiberglass are the filter materials for AHU pocket filters, and they have a few differences. Generally, the dust-holding ability of synthetic material does not as good as that of fiberglass material, and the service life will be shorter.

But its price is better and lower resistance. According to our experience and the market, we recommended using the synthetic HVAC pocket air filter. The filter needs to be replaced every 6 months, or the resistance reaches 3 times the initial resistance. Adding a pre-air filters to extend their life.
