Koch Filter's Multi-Flo is a rigid, extended surface air filter engineered to provide medium and high efficiency air filtration with long filter lifecycles. Its rugged metal and plastic frame construction allows it to operate efficiently across a wide range of air handling systems, making it particularly well suited for variable air volume (VAV) applications where airflow fluctuations may impact non-rigid filters.

The Multi-Flo is available in both single-header and non-header configurations, allowing for flexible installation in side-access or front-access housings. Each unit is fully disposable and provided ready for immediate installation.

Applications

Multi-Flo filters are widely used in hospitals, manufacturing facilities, automotive plants, office buildings, universities, pharmaceutical laboratories, and many other commercial and industrial environments.

Series S Synthetic Media

The Multi-Flo Series S utilizes 100% synthetic fiber media formed into a dual-stage graded density mat. This design ensures full-depth loading, high dust holding capacity, and optimal media utilization.

The synthetic microfibers offer exceptional strength and will not shed, even in high moisture or challenging operating conditions. The media is supported downstream by a layer of spun-bonded synthetic material.

Available in four ASHRAE efficiency ranges, Multi-Flo Series S filters are designed to meet the unique demands of a wide variety of air filtration applications.
