Round duct compact grille type KGRR Description In modern architecture, sheet metal and spiral ducts of air-conditioning systems are often incorporated in the design of the room. Emphasis is often placed deliberately on parts of the supply system. In this visible installation of the ventilation ducts, it is a good idea to integrate the air diffusers into the ducts. The round duct compact grille type KGRR is suitable for installation in supply or return air systems. The air volume throughput can be regulated by using an integrated hit-and-miss damper. The integrated hit-and-miss damper ensures...

Round duct compact grille type KGRR Correction factor (for scattered air jet) with or without coanda effect The angle of propagation of the air jet and thus the length of throw can be affected by adjusting the vertical air deflection blades. Construction subject to change.
