They utilise Celpad filter pads with saturation efficiency of over 80% as well as a non corrosive ABS plastic water tray. The AIRA HCV has a 5 year unconditional Warranty on the stainless steel heat exchanger. They can be fired on LPG or natural gas. The fan is dynamically balanced, centre hung, centrifugal type for strength and long life. The fan can be single or two speed with manual, rotary or VSD controls available. The AIRA HCV includes modulating electronic flame control, leaving air temp compensation, control switching and can have motorised air dampers for low heating air quantities.

Perfect for factories, warehouses, hotels, clubs, restaurants, offices, nurseries, schools and other commercial or industrial applications.  

AIRA HCV's can be effectively set up with a range of options including easy to assemble adjustable galvanised roof stands, alternative location return air and specialised screens for areas with specific conditions such bushfire prone areas. AIRA  HCV units can be installed on the roof or at ground level or even within plantrooms.
