Koch BioMAX HEPA 99.99% — 23.375 in × 23.375 in × 11.5 in

BioMAX HEPA 99.99%

Koch BioMAX HEPA filters are manufactured for high-efficiency commercial and industrial air-filtration systems. Koch identifies hospitals, clean rooms, pharmaceutical plants, and other systems where clean air protects people, processes, and equipment as common product-family applications.

The configured item is a 99.99% filter with actual dimensions of 23.375 × 23.375 × 11.5 inches, a double-turned-flange 18-gauge galvanized-steel frame, polyurethane foam sealant, and one filter per carton.

Construction described by Koch

• High-efficiency media produced from submicron glass fibers formed into a water-resistant, high-density paper mat.
• Precision corrugated aluminum separators maintain pleat spacing and airflow through the media pack.
• The media pack is sealed to the cell-side frame with a polyurethane foam bond.
• Koch literature lists a downstream neoprene gasket as the standard BioMAX arrangement; confirm the gasket arrangement required by your housing before ordering.

Supplied suggested specification

The supplied BioMAX specification calls for a minimum overall efficiency of 99.99% PAO on 0.3 micrometer particles. It describes ultrafine fiberglass media formed into a high-density, water-repellent paper; pleated construction; adhesive-bead pleat spacing; a sealed media pack; UL classification; and a label recording manufacturer, airflow direction, penetration, initial resistance, and test airflow capacity.

Important item-specific note: the generic supplied specification references 26-gauge galvanized cell sides, while the requested PFS-HBM232311 configuration is listed as 18-gauge galvanized DTF. This product page uses the requested 18-gauge item configuration. Confirm any project specification or submittal requirement before purchase.

Ordering check

Confirm the installed filter’s actual dimensions, airflow direction, frame style, gasket arrangement, efficiency requirement, and system airflow before ordering. Contact PFS Filters if the housing or required construction is uncertain.
