The DHV-20B unit is the next step up from the DHV-15B. With an air flow of 150m³/h on low speed, 170m³/h on middle, and 200m³/h on high, the DHV-20B offers a good variation of ventilation, and the highest flow rate of our B series units.

The size of the DHV-20B unit is big enough to facilitate a medium sized property, and yet compact enough to fit comfortably in a loft space. This unit comes with an aluminium heat exchanger that has a heat exchange efficiency of up to 90%, because of this, the DHV-20B comes with a built-in condensate tray.
