FQ Fan Control Cabinet
Single-speed, dual-speed and inverter control with fire-panel and BMS interfaces.
FQ cabinets are built for our fans and for the way fire engineers actually wire them: volt-free fire contacts, damper interlock, thermal protection set to motor full-load current, and a clear naming rule — FQ plus kW plus I / II / F for single, dual or inverter duty.
