K Heavy Duty Adjustable Blade Grilles

    • Product Details


      The Waterloo Series K adjustable, single and double deflection, grilles have been designed for industrial and heavy commercial applications and may be used for supply and exhaust systems. The vanes are screw fixed through nylon bearings to eliminate vane rattle - even at very high supply velocities; the vanes can also be tightened on site to suit individual applications. Grille vanes are individually adjustable to allow jet spread or deflection to be set within 45° of the duct axis.
