Vent Air Valves are perfect for finishing off any ventilation or heat recovery system to a high standard. Finished in a brilliant white, they will blend in to any white ceiling unnoticed.
Air valve vent grilles are easy to for and connect to standard size 100mm (4"), 125mm (5"), 150mm (6") and 200mm (8") duct, ventilation or heat recovery system.
Vent air valve vent grilles are also easy to commission (when setting up and balancing a centralised ventilation system) and adjust for fine tuning. A locking nut is included so when optimal airflow and noise control is achieved, you can simply lock the central cone to set to prevent any future tampering or adjustment. Alternatively, simply spin the central cone to deliver more or less air to suit any bedroom, living room, bathroom or kitchen.
