Vents 4 inch Black Plastic Cowled Air Vent Wall Grill with 100 mm Rear Spigot Ducting Gravity Flap Grille Cover for Hooded Cooker Hood Outlet Kitchen Bathroom Shed Extractor Fan Ventilation

VENTS UK - The product includes a damper flap to help reduce backdrafts. When switched off, the grille shuts automatically with gravity and forms a barrier to stop air from entering the ventilation and protect your grille against birds and rodents. The baffled grille has two advantages: it stops the wind from rattling the shutter and blocks back craft when an extractor fan is switched off.

Smooth installation process and cleaning through the use of the removable blade and duct cowling baffle. Simply push-fit duct and fittings together. This black cowled hooded wall vent baffle with removable single blade back draught shutter is suitable for use with 100 mm 4 inch round ducting and extractor air fan connections. Designed to provide optimum airflow performance. Gravity-operated back draught shutters supply exceptional protection against the effects of high winds and driving rain.

The external dimensions of this cowled vent are 155 mm x 155 mm. Wipe-clean durable design for indoor or outdoor use. The multifunctional cowled grille is suited for bathroom, cooker hood, air conditioning units, kitchen & wet room extractor fans. Suitable to use in compliance with part F building regulations. The grille can be applied as an important part of a ventilation system to terminate any extractor fans, or duct to an external wall.
