A Louvre Shutter is a gravity type shutter which can be used to terminate and weather extract systems. When the fan is running the plastic blades will open allowing the air to be extracted from the system, and when the fan is not running will be closed, this helps to prevent back draughts and water ingress

The shutter is commonly used to terminate systems where a plate mounted fan has been fitted internally, and used for extraction

Louvre shutters are usually either mounted to an external wall or at the end of a galvanised box to terminate an extract system

This Louvre shutter can only be used on EXTRACT systems, for SUPPLY systems please contact us direct, by any means you feel comfortable with and we will advise what should be used to suit your application
