• Galvanized steel construction with flanged duct connection.
• Volume flow controllers work with a smooth-running, asymmetrically angled plate, which guarantees a sensitive responding behavior even in case of low volume flows.
• Control plate is supported by two maintenance free PTFE bearings.
• Flow rate can be easily set or reset within airflow range by using 2 mm Allen key.
• Airflow tolerances:
• Operating temperature range: -30 °C / +100 °C.
• Minimum size: W = 150 mm; H = 100 mm; L = 220 mm
• Maximum size: W = 600 mm; H = 300 mm; L = 385 mm
• Note: Width must be same or larger than Height.

• Airflow is automatically regulated at a pre-set value in rectangular ducts, independently of the varying pressure in the duct.
• Installation of CMEV and air conditioning.
• Air exhaust or air supply.
• Operating pressure range up to 1000 Pa.
