The Plasma Air 600 and 660 Series are needlepoint brush-type ionisers, producing an equal amount of positive and negative ions; neutralising harmful pollutants and odours. These units are highly versatile and may be installed at the fan inlet of an air handling unit, fan coil unit, PTAC, heat pump or VRF ductless split system. Each model is self-contained in a potted box with a molded flange and mounting holes. Models accept 12V DC, 24V AC, 120V AC and 208-240V AC, without the use of an external power supply. The units are protected with an inline 500mA glass cartridge fuse, and are capable of ionising a supply airflow of 2,400 CFM.
