EXTERNAL METAL GRILLE

WITH BACKDRAFT SHUTTER FOR HPA

The EMGB-HPA backdraft shutter is designed for external mounting specifically with the HPA fan. It is made strong and lightweight from aluminium and galvanised steel. Shutters open when the fan is running and close when it is off. This allows air to be ventilated into the atmosphere from the inside of a building, while stopping outside air and pests from entering the building when the fan is off.
