F230, LF230-S Spring Return Actuator – 4 Nm

The F230 and LF230-S spring return actuators are designed for air damper control up to 0.8 m², providing open/close functionality with automatic return to the safe position in case of power loss. These actuators operate on AC 230V power supply and are controlled by a single-pole contact, ensuring efficient ventilation system operation.

These actuators are suitable for operating air dampers that perform safety functions, including:

• Frost protection
• Smoke extraction systems
• Hygiene and air quality management
  
  

• The LF230-S and F230 actuator moves the damper to its normal working position while tensioning the return spring.
• If the power supply is interrupted, the stored energy in the spring moves the damper back to its safe position.
  
  

• Simple and direct mounting on the damper spindle using a universal spindle clamp.
• Includes an anti-rotation device to prevent unwanted rotation of the actuator.
• Adjustable mechanical rotation angle limiter, ensuring flexible operation.
• Overload protection – the actuator does not require additional limit switches and automatically stops at the end position.
• Flexible signaling 0-100% with an adjustable auxiliary switch (LF230-S model only).
