ALD 160 Background Vent System



The ALD 160 Background Vent System has the same external hood and internal cover like the SEVi 160 HRV unit. Inside, the ALD is equipped with a sound proofing layer and a flap, which closes automatically 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.
