Smooth installation process and cleaning through the use of the removable blade and duct cowling baffle. 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. Gravity-operated back draught shutters supply exceptional protection against the effects of high winds and driving rain. 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 multifunctional cowled grille is suited for bathroom, kitchen & wet room extractor fans. The grille can be applied as an important part of a ventilation system to terminate any extractor fans, air conditioning units, cooker hood, or duct to an external wall., Manufacturer: VENTS UK
