Airflow extended surface non-supported pocket filters are designed for use in air filtration systems and equipment where medium to high efficiency filtration is required. Available in a large number of standard sizes, face dimensions, pocket number and depth, and efficiencies, the AIRFLOW Pocket Filter provides optimal performance in constant velocity air handling systems.

• Galvanized steel frame, header and internal pocket support retainers,
• (j-channels) provide strength and rigidity.
• Media is 100% synthetic polypropylene fibers, secured within the inside perimeter of the headers.
• Each pocket is sonically sealed along the outside edges to prevent bypass.
• Available in MERV 11, 13, 14 &15 particle size efficiencies.
• Underwriters Laboratories listed per UL Standard 900.
• Standard header is 7/8” - 1 1/8” header is available as an option.

Typical Applications

For use as a pre-filter for HEPA final filters, or as a stand-alone primary filter in:

• Hospitals and Healthcare Facilities
• Commercial Buildings
• Educational Facilities
• Museums
• Industrial Production Plants
• Food and Beverage Production Plants
• MERV 13 and higher efficiencies for LEED* accredited facilities

Pocket Filter Purchasing Specification
