The Koch Multi-Flo S is a rigid, extended surface air filter engineered to provide medium and high efficiency air filtration, and long filter lifecycles. The Multi-Flo, because of its rugged metal and plastic frame construction, is capable of operating in a wide variety of air handling systems, and is an excellent product for variable-air-volume (VAV) applications where changes in airflow might render a non-rigid filter ineffective.

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

The Multi-Flo S is interchangeable with all makes and models of competitive rigid filters. They are available in a single-header, double header or no header configurations, making it easy to install in any side access or front access housing. Each filter is completely disposable and is furnished ready for installation.
