Inline Rectangular Duct Fans
The Soler & Palau IRB / IRT series comprises high-performance centrifugal inline rectangular duct fans designed for general ventilation applications in rectangular duct systems and installations with limited space. The fans feature a heavy-gauge galvanized steel casing and direct-drive, backward-curved impellers manufactured from aluminium sheet. All models can be installed in any orientation. The motor and impeller assembly is mounted on the inspection cover to facilitate cleaning and maintenance. Additional features include an external rotor motor, Class F insulation, thermal protection, and a remote terminal box. IRB models feature single-phase 230 V, 50 Hz motors, with IP44 or IP54 protection depending on the model, and transformer-based speed control. IRT models feature three-phase 230/400 V, 50 Hz motors with IP54 protection. Speed can be controlled using a transformer or frequency drive. Dimensions, airflow performance, motor power, and electrical characteristics vary by model. Consult the manufacturer's technical data before selecting a fan.
