Air flow regulator LVC

FOR LOW AIRFLOW VELOCITIES AND LOW DUCT PRESSURES Circular VAV terminal units for supply air and extract air systems with variable volume flows, low airflow velocities and low duct pressures New measurement principle, optimised for airflow velocities from 0.6 to 6 m/s High control accuracy even in case of unfavourable upstream conditions Electronic control components for different applications (Easy, Compact) Easy handling due to innovative controls Casing length of only 310 mm for all nominal sizes Any installation orientation Closed blade air leakage to EN 1751, up to class 2 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 Circular VAV terminal units for variable air volume systems with low airflow velocities, suitable for supply or extract air, available in four nominal sizes. Measurement and control of low volume flow rates based on a new measurement principle. Plastic nozzle with damper blade for measuring the differential pressure upstream and downstream of the damper blade (effective pressure). The relation between damper blade position and differential pressure is stored as a characteristic relationship in the Easy or Compact controller. This results in high control accuracy even in case of unfavourable upstream conditions. Commissioning ready device, consisting of the mechanical components and the electronic control components. Units are equipped with a plastic nozzle with integral damper blade.
