Adjustable Single Deflection Grille

A single deflection grille does one thing well: a single row of adjustable blades sets the air pattern once, and it stays set. Extruded aluminium, powder coated to any RAL shade, sized to your wall opening: the dependable side-wall terminal for supply and return air.

Common questions

What is a single deflection grille used for?

Side-wall supply and return air where one plane of adjustment is enough: set the blade angle once and the air pattern stays set.

Single or double deflection: which do I need?

Single deflection adjusts one axis and suits returns and simple supplies. Double deflection adjusts both vertical and horizontal and is the choice when air must be aimed precisely.
