Blauberg Vento Maxi Midi Mini & Duo-Air Heat Recovery Unit External Cowl for Thin Walls.

Brand new, damaged box. In the end our walls where just thick enough so we didn't need External Cow. New price 94.57 pounds. I sell it for 80 pounds, excl delivery costs.

Main Product Features

A robust, metal external wall cowl designed to be used when fitting Blauberg Vento single room heat recovery units into thinner walls or SIP panels.

When fitted, the externally protruding duct is housed inside the cowling unit, thus allowing installation within thinner walls down to 150mm.

For Vento Duo-Air, an airflow splitter within the vent acts to separate intake and extract airflow. Both airflow's are then forced horizontally out of either side of the vent and through louvred vents to stop any cross contamination.

For Vento Maxi-Air, Midi-Air and Mini-Air; no airflow splitter is required as the air intake and extract airflow's are directed through the cowl and horizontally out of either side of the vent.

The metal outer cowl consists of two parts to allow easy installation and maintenance.The cowling vent also has a small drip tray to direct any condensated water away from a wall or window.

For use with Blauberg Vento Single Room Heat Recovery Units.

Compatable with Duo-Air, Maxi-Air, Midi-Air and Mini-Air heat recovery.

Suitable for wall thicknesses from 150 to 500mm.

Manufactured from white powder coated stainless steel.

Designed to be externally mounted to provide a weather poof solution
