KVS-Volumenstromregler

Circular mechanical self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems with low airflow velocities

• Suitable for airflow velocities from 0.8 m/s
• Very simple commissioning
• Volume flow rate can be set using a rotary knob and a scale on the outside of the casing
• Simple retrofit of an actuator for variable volume flows
• Any installation orientation; maintenance-free
• Casing air leakage to EN 1751, class C

Optional equipment and accessories

• Circular silencer Type CA or CF for the reduction of air-regenerated noise
• Hot water heat exchanger Type WL and electric air heater Type EL for reheating the airflow
• Actuator for variable volume flows or for qv_min - qv_max switching

Rectangular, mechanically self-powered air terminal units for supply and extract air systems with constant air volume flows

• Suitable for volume flow rates up to 12600 m³/h or 3500 l/s
• Volume flow rate adjustment from outside by rotary knob
• Easy retrofitting of an actuator for volume flow setpoint adjustment
• High control accuracy
• No on-site test measurements required for commissioning
• Casing air leakage to EN 1751, class C
• Visual display of the damper blade position for operating point optimisation
