Blauberg Plastic Vented Back Draught Air Gravity Shutter Ventilation Grille - 100mm Cotswold Stone

An essential part of a ventilation system is to terminate any extractor fan, cooker hood or duct to an external wall. This Blauberg Decor gravity shutter is a rain and weatherproof vent designed to fit to an external wall and is finished in cotswold stone. Five other aesthetically pleasing colours with black and grey fast becoming popular choices to meet the demands of modern architecture and designer features. This size has a 100mm 4" dia duct or extractor fan connection. Simply use a short piece of duct or a telescopic wall sleeve together. Each Decor gravity shutter vent has removable blades for easy installation and cleaning. The shutter works by extract air opening the blades to allow air to pass. With the extractor fan or ventilation system is switched off, the grille shuts automatically with gravity and forms a barrier to stop air entering the room.
