CE 140 S-125

The CE 140 S-125 is a centrifugal fan with forward curved blades and an external rotor motor. The fan is designed for duct installation with speed control and can be installed in any position. The fan casing is made of galvanized steel sheet. The intake and exhaust are fitted with rubber seals. The speed of the centrifugal fan can be controlled by a 5-stage transformer or also continuously by a thyristor. The CE 140 S-125 is a multi-purpose, acoustically optimised fan in a compact, space-saving design. The duct fan has forward-curved blades that ensure uniform airflow without the use of a guide plate in order to achieve the highest efficiency and quiet, vibration-free operation. The motor is equipped with built-in thermal contacts routed to an external motor terminal block, which must be connected to the corresponding thermal protection relay.
