Wholehouse Ventilation System

The Addvent AVWH wholehouse ventilation system is designed for continuous operation – eliminating cross-contamination – and is ideal for simultaneous ventilation of multiple areas. With automatic regulators on each of the inlet spigots controlling air volume and pressure, installation and commissioning are simple and cost effective regardless of duct length. Offering excellent performance and efficiency the AVWH system is suitable for new-build or ‘total-refurb’ applications, avoiding the need for multiple systems. Quiet in operation, it can be wall, ceiling or loft mounted and is available as an AC or a ‘Green Spot’ low-consumption DC installation.

With three integral fans speeds and an over-run timer, the unit can also be controlled via an optional remote switch or sensor enabling the user to automatically select ventilation levels. Suitable for up to 3 rooms and a maximum air flow of 500m3 /hr with the appropriate ducting.
