Pocket filter for AHU replace
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, and pocket lengths vary from 200mm to 1000mm. customized sizes available and accept OEM/ODM.

- Frame: aluminum alloy or galvanized steel
- The thickness of the frame: 21mm or 25mm
- Filter media: glass fiber or polyester
- V design to the maximum air filter area
- Large dust collection
- Efficiency: 45%, 65%, 85% , 95% ( F5, F6, F7, F8 )
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, 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 little differences. Generally, the dust holding ability of synthetic material does not as good as that fiberglass material, and the service life will be shorter. But its price is better and lower resistance. It is generally recommended to use the Synthetic HVAC pocket air filter. The filter needs to be replaced every 6 months, or the resistance reaches 3 times of the initial resistance. Pre-air filters can be added to extend their life.
The application range of pocket filter is very wide. Most of the ventilation systems of commercial buildings and air conditioning systems need this. It is cheaper of price, convenient to install, long in service life and has an excellent dust removal effect. However, it cannot be used in wet environments. If the environment is humid, it is recommended to use V bank filter instead. The HVAC pocket air filter can also be used as a pre-filter for the HEPA filter to help remove particles above 5 microns and increase the life of the HEPA filter.
