The SDA is used for the quick and easy regulation of supply air flows in ventilation systems. Due to its design, the device has a wide flow range that can be continuously adjusted and then fixed in place

  • 5 sizes from Ø 80 to 200 mm
  • Easy to install and adjust
  • Can be mounted directly in the duct or with a mounting frame (accessory)
  • Low noise levels

SDA is manufactured from galvanized steel sheet. The product consists of a valve housing, duct connection with fixing springs and the adjustable front panel. The front panel is held by the central thread bolt and can be moved by rotating. The gap between the plate and the seat can be adjusted to set the required air flow volume. The product is powder painted to RAL9003 (signal white) as standard. Other RAL colours are available upon request
