The ComfoSpot 50 needs a ~340mm core through an external wall with a minimum depth of 335mm up to 600mm. Extension pieces are available.
Compared to the ComfoAir 70, the ComfoSpot 50 is a quieter de-central solution when no ducting is to be connected. If ducting can be connected, then the ComfoAir 70 is a quieter solution.
The ComfoAir 70 needs a ~270mm core through an external wall with a minimum depth of 275mm up to 600mm. Extension pieces are available.
Compared to the ComfoSpot 50, the ComfoAir 70 is a quieter solution when ducting can be connected.
The ComfoAir 70 has 100mm duct connections on its side and back.
Only one supply and one extract room can be connected to the MVHR unit.
The EPP end cap on the back can be taken out and inserted into the side port, when ducting is connected to it.
Possible ducts that can be connected:
