Grille Selector
Further to requests from our customers we have produced this Quick Grille Selector in order to make your life easier and save you time.
The selections have been made to keep pressure drops and noise generated at the Air terminal Device low. All noise ratings are below NR35.
If pressure drop, noise rating or throw are critical please refer to the individual date sheets or speak to our technical sales team on 0191 461 0077.
The selections within this table are applicable to Gilberts products only and should not be used to select other manufacturers products.
