## Long description

The FANAR fan coupling hub Zabierak M20 with clutch FZS31 (R-FZS31/M20D16DIN) is a mechanical coupling designed to join fan blades or drive hubs to shafts using an M20 mounting interface while providing controlled disengagement through the integrated FZS31 clutch. This unit transmits torque between the motor and the fan assembly and is intended for use in industrial ventilation, cooling and blower systems where overload protection and safe decoupling are required. The design accommodates typical fan drive arrangements and simplifies replacement or retrofitting of clutch-protected couplings.
Advantages
The FANAR Zabierak M20 with FZS31 clutch offers torque transmission combined with overload protection and automatic decoupling when preset torque limits are exceeded. Its M20 mounting interface provides compatibility with shafts and hubs that use metric threaded connections, and the integrated clutch reduces the risk of damage to downstream components during jam or stall events. The product is manufactured to industry-appropriate mechanical standards and is suitable for straightforward installation in existing fan drive systems.
Suitable for
Industrial ventilation systems
Cooling towers and heat exchangers
Blower and air-handling units
Retrofit and replacement of fan couplings with overload protection
Key specifications
Mounting interface: M20 threaded connection

How to use
Mount the FANAR Zabierak M20 on the driven shaft using the M20 threaded interface and secure according to the mechanical fastening requirements of the installation. Align the coupling hub with the fan blade hub or drive component to ensure concentricity and minimal runout. Adjust and set the clutch engagement torque as required by the system specifications, following any torque-setting procedure provided by the equipment designer or service documentation. After installation, perform a trial run at low speed to confirm correct engagement and absence of abnormal vibration or noise.
Usage recommendations
Use the coupling hub in environments and applications consistent with industrial fan and blower equipment; ensure routine inspection of mounting threads and clutch function, and replace the unit if signs of wear, corrosion, or repeated clutch disengagement occur.
