From £9.74 - £85.95


Galvanised steel circular backdraught shutters with aluminium blades for mounting in between 2 ducts.

For airflow control in ventilation systems. The aluminium blades will open when blades are exposed to overpressure and will shut again when pressure falls away, thanks to a stainless steel mechanical spring.

The body is constructed from galvanised steel. The Blades are made of aluminium.

They will be mounted in between two ducts to prevent backdraught when the fan stops.
