A Complete Line of HEPA Filters for Hospital, Commercial and Industrial Applications

Koch Filter Corporation BioMAX HEPA Filters are designed to provide the highest level of filtration available for commercial and industrial applications. They are widely used in hospitals, clean rooms, pharmaceutical plants, and in hundreds of other systems where clean air is critical in the protection of people, processes and equipment.

BioMAX HEPA Filters are constructed using the highest quality components available and are available in efficiencies of 99.97%, 99.99% and 99.999% on 0.3 micron size particles.

Standard construction BioMAX HEPA Filters are manufactured with galvanized steel cell sides (UL Class 1) or particle board cell sides (UL Class 2). Multiple cell side options are also available.

BioMAX Performance Testing

Prior to shipment, BioMAX HEPA Filters are tested individually for efficiency utilizing non-toxic polyalphaolefin (PAO) to insure that every filter meets the customer’s required efficiency specifications.

Following the individual efficiency test, depending on the acceptance criteria chosen by the customer, BioMAX filters may also be scanned for pinhole leaks with the use of a specialized high intensity light or a custom-built laser photometer.

After testing to the customer’s criteria, each filter is certified and labeled with its own serial number. All data is recorded and retained internally.

BioMAX Versatility

BioMAX HEPA Filters are extremely versatile and are used in a wide variety of filtration systems worldwide. In order to meet the wide range of airflow requirements, atmospheric conditions, and pressure drop parameters found in these diverse applications, Koch offers the BioMAX in two media area capacity levels and in multiple construction configurations for specialized applications.

Two Media Area Capacity Options

Standard Capacity BioMAX

Standard Capacity BioMAX Filters offer an excellent combination of high efficiency, factory tested performance, and economical initial purchase price.

The filter is designed to operate under normal conditions, with the 12″ deep model capable of maintaining a pressure drop of 1.0″ w.g. at airflows up to 260 feet per minute.

Standard Capacity BioMAX Filters are offered with wood or metal cell sides in efficiencies of 99.97%, 99.99%, and 99.999% on 0.3 micron particles.

High Capacity BioMAX HC

High Capacity BioMAX HC Filters are designed to operate in applications with higher airflows up to 500 FPM (Feet per Minute). Constructed with approximately 50% more filter media than Standard Capacity Filters, High Capacity BioMAX HC Filters can operate at velocities up to 2000 CFM with only a slight increase in pressure drop and offer several additional performance advantages:

  • Lower average pressure drop at equivalent airflows.
  • Can operate at higher airflows with only slight increase in resistance.
  • Extended media area means longer service life, fewer filter changes, and reduced maintenance and disposal costs.
  • Reduced space requirements for filter banks, fewer filters required.
  • Excellent choice for new systems and renovations of existing systems.

High Capacity BioMAX Filters are offered with wood or metal cell sides in efficiencies of 99.97%, 99.99%, and 99.999% on 0.3 micron particles.
