The Polypipe Domus HRXD and HRX2D MVHR units are designed to provide measured amounts of filtered, fresh air to living areas while removing polluted, stale air from bathing, cooking and washing areas at a similar rate.
Both units feaute a built-in heat exchanger to recover the heat from the extracted air as well as a boost switch to increase the ventilation rate when required (for example when the shower is running and producing water vapour).

Polypipe Domus HRX2D: This unit is bigger than the HRXD and is suitable for a floor area between 180m² to 275m².
NOTE: If the floor area is greater than 275m², then multiple units can be used.
