AireGard™ NU-105 Air Cleaning Ceiling Module

The AireGard™ NU-105 Cleanroom Air Shower was developed to provide an inexpensive solution for laboratories and facilities looking create a sterile clean room having Class 100 Air through HEPA filtration.

Part #: NU-105


The AireGard™ model NU-105 Recycling Ceiling Air Module offers a powerful but inexpensive air filtration solution for maintaining Class 100 Air in facilities requiring a sterile clean room. Its powerful HEPA filters are 99.99% efficient on particles down to 0.3 microns, and a pre-filtration system captures larger contaminants such as pet hair, dander, and clothing fibers. The Recycling Air Module performs the function of flushing the air in a room in a different manner by recycling the air in the proximity of the Module. The installation of the Air Recycling Module limits the need for remote blowers or return air ducts resulting in lower costs. Flexible installation options allow the placement of a single unit for a small clean room or multiple units to maintain air quality in larger spaces. The modules can be equipped with fluorescent lighting to provide an all-in-one solution for both illumination and air filtering, and additional customization is available to meet any installation requirements.
