Construction - the fan consists of a hot-dip galvanized steel housing to which an external motor is attached. This motor is placed outside the active part of the fan. The suction opening can be protected with a mesh or adapted for a fitting mounted to devices (e.g., gas radiators, spiral pipes). The outlet opening ends with a round flange adapted for connecting the exhaust pipe.
Control - the fan is standard equipped with a Hall sensor (Hall Sensor IC), which when connected to the appropriate controller allows very precise regulation of the fan's rotational speed.
