Volume flow rate balancing -*G 00152008_0

Attachments -AG, -DG and Types AGW, DGW

Volume flow rate balancing

When several ventilation grilles are installed on the same duct, it may be necessary to balance the volume flow rates.

AG: Damper unit with opposed action blades, adjustable, secured with a locking screw
AS: Damper unit with hit and miss damper, adjustable, secured with a locking screw

Air pattern

Adjustable blades: Set the air control blades individually or together and depending on the local conditions
D, DG: Air control blades, fitted at 90° to the front blades, can be adapted to the local conditions
