Devola 150mm Gravity Grill, White - DVGG150W

Devola 150mm Gravity Grill, White - DVGG150W. The Devola 150mm Gravity Grill in white is a practical and discreet solution for ventilation systems requiring protection from backdraughts. Designed with gravity-operated shutters, the grill automatically opens when airflow is present and closes when the system is off-helping to prevent unwanted air, insects, or debris from entering the ducting. Its 150mm round male rear spigot fits standard ducting and can be easily installed for use with extractor fans or passive ventilation.. With a durable plastic body finished in white, the grill blends well with external walls, particularly brick. Its 186mm x 186mm square front and 50mm depth offer a flush, low-profile appearance, while the lightweight design ensures simple, push-fit installation without the need for tools or sealants. Ideal for kitchens, bathrooms, and utility rooms, it offers reliable performance both indoors and out.
