Metal ventilation grilles

MTA metal ventilation grille

The ventilation grilles in the MTA series are made in whole of stainless sheet steel or galvanised steel and coated with a durable epoxy finish. They are fitted with mesh preventing ingress of insects. Unlike the MT, the MTA grille does not have a flange.


The installed nylon mesh protects the ventilation ducts against insects.
