Description

FOR LOW AIRFLOW VELOCITIES 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 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 variable volume flows or for Vmin / Vmax switching Circular volume flow controllers for constant and variable air volume systems with low airflow velocities, mechanical self-powered, without external power supply, suitable for supply or extract air, available in 6 nominal sizes. Ready-to-commission unit consists of the casing containing a damper blade with low-friction bearings, bellows, leaf spring, and a rotary knob to set the volume flow rate setpoint. SPECIAL CHARACTERISTICS - Setting the volume flow setpoint without adjustment device from the outside on a scale - Simple retrofit of an actuator is possible - Perfect function even with upstream conditions and downstream conditions (straight upstream section 1,5D) - Any installation orientation - Factory functional testing of each unit using a dedicated test rig
