Air flow regulator KCRK

The circular constant flow control damper KCRK, (with adjustable option) is a control component that functions independently of pressure and without an external power supply. It can be considered “self-regulating” at pressures between 50 and 250 Pa, thus maintaining the necessary air volume flow. Consequently, this air volume regulator make costly system balancing unnecessary by ensuring constant air volume. It includes an adjustment device to manually adjust the factory-set air volume flow on site. Product description Constant air flow adjustment, KOOLAIR KCRK model, of circular cross-section of size Ø_ for air supply or return. Manufactured in ABS AF312A-class plastic material with flammability V0. Automechanical, with no need for outside power, ensuring constant air flow regardless of the pressure variations experienced by the system. Housings and blade of high-quality plastic. They are regulated from a pressure loss of 30 Pa, except diametre 80 that regulates in 50 Pa. Can be installed in horizontal or vertical position
