ALD 160 Background Vent System



The ALD 160 Background Vent System has the same external metal hood and internal cover with integrated filter like the SEVi 160 HRV unit. Inside, the ALD is equipped with a sound proofing layer and a flap, which closes on high wind speeds.

The biggest advantage of the ALD 160 background vent system in comparison to standard vents is the fact, that you can upgrade the vent into a full ductless HRV unit in your own time. 

Whenever you decide to install background vents, select the right version to allow a later upgrade.


Available for the following wall thickness:

up to 480mm (standard)

up to 650mm (surcharge)

up to 850mm (surcharge)


The external hood is available in white (RAL 9016), grey (RAL 7016) or plain stainless (which we do not recommend in coastal areas).
