Adjustable single deflection straight blade grille for side wall application for most domestic and commercial projects. Grille blades are of tear drop design and individually adjustable for optimal air distribution.

Description:

Manufacture: VM series of supply air grilles are constructed from high quality aluminium (6063-t6) alloy extrusions. Frames are mitered and cleated. Tear drop type blades are individually adjustable and separated from frames with injection moulded nylon bushes to eliminate corrosion & vibration. At the outer edge of the frame is a specially engineered channel which retains an extruded flexible vinyl gasket that produces a positive air seal. Flange mounting holes are dimpled to allow counter sunk screw heads. The grille blades and damper blades are mounted in the same extrusion frame.
Damper blades are secured in position with stainless steel spring wire.

The Parallel blade damper is operated from the face of the grille with an aluminium operator lever

Sizes: Square & rectangular patterns are available as per listed size in inches.
