• The UDD universal double deflection grille is generally used in sidewall applications. It consists of two separate rows of individually adjustable vanes.
• The front vanes are horizontal so the primary air leaving the outlet is directed above the room occupants and does not reach the breathing zone until well mixed with the secondary air.
• The rear vanes are vertical and are used to direct the air in a straight blow or spread as required by the room layout. If required, air can be directed at an angle to one or both sides and still retain a near parallel air stream pattern.
