The air flows through an opening inside the air volume flow controllers, in which the damper changes position according to the specified air flow volume. The built-in damper is connected to a calibrated spring, so no additional actuator is required. The damper can be adjusted using a locking screw. The air flow change is only possible in the given range of the controllers, which is specified in the product code. The RDR is a *constant air volume flow controllers**, which is made of plastic (polymer) in grey, classified M1. The operating range of air temperatures is +5 to +60 °C. Installation The RDR is an air volume flow controller that can be installed directly in a circular air duct in a vertical or horizontal position. For horizontal installation, the notice DOWN on the controller must be observed. Thanks to the seal on the controller housing, tightness in the ductwork is guaranteed. For correct function, it is necessary to ensure a straight duct in front of the controller (L ≥ 1 x ØD) and behind the controller (L ≥ 3 x ØD). Care must be taken during installation to avoid damaging or blocking the damper! - Additional Information
