BETTERAIR range of TERMINAL MODULE are light weight unitised low profile disposable ducted units with minipleat HEPA filter packs designed to provide unidirectorional airflow from tee-bar ceiling. BETTERAIR TERMINAL MODULE are available in two sizes : norminal 24" X 24" (600 X 600mm) and 24" X 48" (600 X 1210mm) with nominal 10" (250mm) diameter inlet collars and in two particle size efficiencies : 99.99% and 99.999%. Each module is scan-tested after assembly.

The heart of the BETTERAIR module is a state-of-art minipleat filter pack sealed in an anodised extruded aluminium casing forming the sides of the module. The extruded aluminium centre divider holds ports for in-room damper adjustment. The one piece hood/inlet collar. An expanded steel white powder coated face grille protects the media pack.

BETTERAIR TERMINAL MODULES are recommended for use in clean room application for fabrication of microelectronics, semiconductors and medical devices, in aerospace, biotech and pharmaceutical manufacturing and in other applications that require ultra clean air.

Clips on the module's top four corner are to be used to secure seismic restraint wires. Polyfoam gasket should be applied to be the tee-bar surface on where the module will rest. The standard face velocity range of 70 to 110 fpm (0.35 to 0.50 m/s) easily adjusted from the room side by a screwdriver-operated damper. Static pressure and challenge aerosol measurements (Optional item) can be taken from a separate room side port. Standard construction allows the modules to be operated at a pressure drop of 2.0 inches (500Pa) W.G. High efficiency prefilters with a minimum rating of 80-85% ASHRAE standard are recommended.
