ENG and DNG marine centrifugal fans are used in the ventilation system of seagoing ships with unrestricted cruising area as well as offshore objects. The fans can be used as exhaust or supply fans and be installed inside the compartment. The 1-phase drives (ENG) can be adjusted directly. The 3-phase drives (DNG) can be adjusted by a converter. DRIVE All drive motors employed are designed for continual operation and comply with the valid VDE regulations, Euro-norms and accident prevention regulations. IMPELLER SPEED All employed fan impellers are dynamically balanced in two planes. The balance quality is according to DIN ISO 1940. With the low-pressure fans, fans with split-pole motors and external rotors, forward-curved drum-type rotors (DNG 9-30) or backwardcurved high-performance impellers are employed. The standard material is galvanized-steel plate. DIRECTION OF ROTATION The direction of rotation is defined in relation to the suction side of the fan. The standard design is clockwise rotation. Unless otherwise specified in the order, the motor is mounted at: clockwise rotation: foot R90, terminal box RO anticlockwise rotation: foot R90, terminal box RO
