Differential pressure flow controller RN

for air

For the precise control of constant volume flow rates Circular self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems Volume flow rate can be set using an external scale, no tools required High control accuracy No on-site test measurements required for commissioning Suitable for airflow velocities of up to 12 m/s Any installation orientation; maintenance-free Casing air leakage to EN 1751, class C Optional equipment and accessories Acoustic cladding for the reduction of case-radiated noise Secondary silencer Type CA, CS 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 switching between setpoint values
