STJH-VARIABLE-AIR-VOLUME-CONTROL-DAMPER-DN100

Variable Air Volume Control Damper DN100 Electronic

Compact electronic flow regulation for small circular ventilation branches.

Small connection footprint suits individual room takeoffs.
Accessible controls keep adjustment outside the airstream.

Introduction de produit

A short round casing houses a pressure pickup and rotating blade. The external control assembly compares measured flow with a room demand signal and adjusts the opening, making the unit suitable for branches where a fixed balancing setting cannot follow changing use.

Key Features

Small connection footprint suits individual room takeoffs.
Accessible controls keep adjustment outside the airstream.

Solutions for Your Application

A small branch can receive excessive air when system pressure rises.

Closed-loop regulation changes blade position as measured flow departs from the setpoint.

Ceiling space around the takeoff is limited.

The compact circular body connects directly to the small round branch.
