Air Grilles for HVAC Systems

Double Deflection Register – Fixed Core

Double Deflection Registers are generally used in sidewall applications. They consist of two separate rows of individually adjustable vanes - front and rear.


  • Front Vanes – horizontal so the primary air leaving the outlet is directed above the room occupants and does not reach the occupied zone until well mixed with the secondary room air.
  • Rear Vanes – vertical and are used to direct the air in a straight blow or spread the air as required by the room layout. If required, air flow can be directed at an angle to one or both sides, and still retain a near-parallel air stream pattern.
  • Construction is all extruded aluminium horizontal and vertical blades, retained in a fixed or removable Core.
  • Standard finish is powder coat white while other finishes are available to suit the interior and architectural design requirements.
