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, the units can be wall, ceiling or loft mounted and are available as an AC or a ‘Green Spot’ low-consumption DC installation.

AVWH1 – AC VERSION
With three integral fans speeds and an overrun 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 5 rooms simultaneously and a maximum air flow of 500m3/hr with the appropriate ducting.

AVWH2N – DC VERSION ‘GREEN SPOT’
The AVWH2N can be set to ventilate a combined area of up to 444m3. The potentiometer-controlled speed selector offers accurate airflow setting for exactly the right ventilation rate whilst also reducing noise levels and energy consumption. The unit has 2 fully variable speeds for trickle and boost, with a switched activation to the higher speed when required. The AVWH2N complies with the Building Regulations for continuous running.
