100mm External Wind Baffle Vent Black

A brilliantly designed black external wall vent that meets the needs of any ventilation system. They look great, reduce internal and external noise, and are easy to fit onto any external wall.

This Blauberg AH-10 vent cover will flush fit to an external wall and is intended for installation using 100mm 4" diameter solid duct.

When used and an air intake vent serving a heat recovery system (MVHR), positive input ventilation (PIV), mechanical extract system (MEV) or single room heat recovery unit, air is drawn in from opposite sides of the vent through louverd vents. Air also passes over a sound adsorbing lining to dampen airborne noise. This ensures weatherproofing and reduced noise without the need of a mechanical shutter or noisy back draft flap.

As an air extract vent, expelling dirty air from a heat recovery system, bathroom extractor fan or kitchen cooker hood, air passes over an airflow splitter and noise dampening liner. Extract air is then pushed horizontally out of either side of the grille and slotted louvred vents.

When used with a Blauberg single room heat recovery unit, the 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 vent to stop any cross contamination.

The stylish outer cowl is aesthetically pleasing and will suite any modern building or blend into a traditional house. A small drip tray is also included to direct any condensated water away from a wall or window.
