    • Product Details

      Introduction

      The Waterloo 1RV & 2RV are designed to fit directly onto the side of an exposed circular duct without the need for a stub duct or transition piece. The flange is supplied complete with a foam sealing gasket on all 4 sides.

      These units can be provided with either a single row of vertical blades, or a set of vertical blades at the front and a set of horizontal blades at the rear. There are a range of sizes for each grille to suit ducts from Ø125 - Ø1500. Each grille can be supplied with an aluminium opposed blade damper if required.
