/13 | RK & RKT Description RK and RKT are control dampers for rectangular ducts. They are available with blade tightness class 1 (RK) or 2 (RKT), tested according to EN 1751. They can be used as control dampers for air flow adjustment. RKT is also foreseen as a shut-off damper in case of lower tightness requirements. The dampers can be supplied in a manual version with adjustment handle or with preparation for attachment of an actuator. The maximum recommended duct pressure for operation is 1000 Pa.
