Pocket Filters

Maximizing Airflow with Extended Surface Filters

When optimizing a commercial ventilation system, upgrading to a high-quality pocket air filter (often referred to as an extended surface filter or pocket bag filter) significantly improves dust retention. Available in various grades from medium efficiency pocket filter designs to fine f8 bag filter specifications, these units are essential for reducing HVAC strain.

Whether you require a standard synthetic pocket filter for office buildings, a robust fiberglass pocket filter for industrial facilities, or specific replacements like a 24x24x22 bag filter, our multi pocket filter configurations guarantee exceptional performance and lower maintenance frequency.

Precision Manufacturing & Stringent QC

Every filter is constructed using advanced bonding techniques to eliminate air bypass and ensure structural stability.

Aerodynamic Internal Spacers

Specially designed internal stitching or spacers keep the pockets fully inflated, maximizing the effective filtration area.

Ultrasonic Seamless Welding

Filter pockets are constructed using advanced ultrasonic welding to prevent air leakage and ensure high burst strength.

Dust Holding Capacity Testing

Rigorous laboratory testing validates the dust holding capacity and structural integrity under maximum rated airflow.
