The galvanized steel casing is insulated with fire-resistant mineral wool. The mounting rails with rubber pads can be repositioned, offering three discharge directions. The standard connections have double gaskets for a tight seal. The base includes a condensate/grease collection tray (usable only for upward discharge) and a drainage connection.
The fan, equipped with a bracket and a tiltable inverter, allows easy maintenance access. The dynamically balanced steel impeller is mounted on a three-phase IEC motor with special sealing and maintenance-free bearings. The speed can be controlled by a frequency inverter, and the motor – located outside the airflow – requires external thermal protection.
