The Brookvent airstream Xe is a discreet intermittent decentralised mechanical ventilation unit which is perfectly suited to utilisation in both new build and refurbishment projects. Airflow is maximised whilst noise is minimised, thanks to the unique fan impeller design, which reduces turbulence. Mount either on wall, panel, window or ceiling, and extract stale air either directly to outside or through a short run of ducting, for the ultimate in versatility.
