Air Filter Housings

MANN+HUMMEL offers a wide variety of air filter housings and filter frames suitable for HVAC, Power Generation, Clean Room and Industrial.



NG is a range of filter duct housings suitable for air flows of up to 12,000 m³/h. The housings are designed for the installation of various filter types, including HEPA/ULPA filters and activated carbon units, which can all be used with or without an integrated prefilter.

NG are fast and easy to assemble and are available in a multitude of sizes. In addition, single NG elements can be combined by removing the side cover plate to form larger units, or alternatively, installed in a series to create a multi-stage system.

Installed directly in duct systems for the supply of ultra-clean air, NG can manage both horizontal or vertical air flows as required and servicing can be conducted from the sides or underneath. The housing, mounted as closely as possible to the air outlet, allows conventional air distribution meaning that the filter can be changed from outside the clean air zone.
