A robust, metal external wall cowl designed to be used when fitting Blauberg Vento Maxi-Air and Midi-Air 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. 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.
