IRB duct fan

The fan is for installation in ventilation systems. It can be installed outdoors or in humid environments. IRB is equipped with 50 mm thick thermal and acoustic insulation, which makes it perfect for handling cool air. It is designed for high pressure and long ventilation ducts. The priority for design was high functionality, durability, and service life. Airflow up to 13,300 m3/h (3,70 m3/s). IRB is available with either an AC motor or EC motor. The impeller blades are backward curved. Swing-out ensures easy cleaning and maintenance.
