we have 2 of the popular 450mm square air transfer plates in our clearance area as they are slightly bent, still perfect to fit.
The largest sector of our air transfer plates, the 450mm mild steel grilles are designed to satisfy all types of air transfer application in offices, shops, schools, hospitals and many other commercial projects.

Suitable for surface mounting in both door and wall internal applications, each plate is fabricated from 2Oswg mild steel and comprised of horizontal louvres set on an 8.5mm pitch with a 30% downward deflection. 
Please Note: The size stated is for the grille it is designed to cover and not the actual size, and therefore these are larger with a 25mm frame.

Other sizes available on request.
The clearance air transfer plates are exempt from our standard returns policy.
