The sterilAir AQD54 is around 90cm long, and at the default radiation recommended for drinking water of 400 J/m², offers a maximum disinfection volume of approx. 1,500 litres/hr.

The light-transparent reactor tube is impervious to short-wave UV radiation, and allows a rapid visual check of the built-in UVC radiation source. Connection to a sterilAir UES2000 increases operational safety.
