CVCWL - Circular External Weather Louvre

Product Overview

Our circular external louvres offer a fantastic alternative to traditional square and rectangular louvres.

CVE Shop small diameter external louvres are designed for applications requiring a high free area external vent, perfect for bathroom extractor fans etc. 

When using circular ductwork or flex, the duct will connect directly over the louvre spigot without using a transition piece.

Manufactured from cast aluminium, the louvre is very robust and rattle free.

The circular weather louvre also offers excellent resistance to rain whilst maintaining a 50% free area.

The circular weather louvre can be fixed through the face into the substrate (supplied undrilled), or by using the two concealed holes in the rear spigot.
