Produkteinführung

The compact cylindrical body contains a low-friction blade, damping bellows and spring mechanism. An external setting scale establishes the desired airflow; the internal balance adjusts the blade as duct pressure changes.

Key Features

No external energy is needed for basic constant-flow operation.
The small-bore format suits localized supply or extract branches.

Solutions for Your Application

Branch flow changes when other ducts open or close.

The mechanical balance varies blade resistance in response to the pressure change.

Power wiring is unavailable at the branch.

Airflow forces operate the basic regulator without an electrical supply.
