Belimo AV6-20 Shaft extension

The Belimo AV6-20 is a heavy-duty shaft extension 170 mm designed for professional HVAC mechanical installations where the standard damper shaft length is insufficient for actuator mounting. This accessory provides a critical 6.7-inch extension, making it indispensable for deep-set dampers or applications with thick insulation. Crafted from galvanized steel, the AV6-20 is engineered to withstand high-torque environments without slipping or losing alignment. It is compatible with a wide range of damper shafts measuring between 6 mm and 16 mm (1/4" to 5/8") in diameter. This Belimo actuator accessory is specifically designed to interface seamlessly with CM, LF, LM, LMC, TF, and TMC series actuators, ensuring a secure mechanical link and consistent control signal response. For technicians, using this HVAC damper shaft extension ensures that the actuator can be positioned correctly for maintenance access while maintaining a rigid, reliable connection to the damper blade assembly.

• Broad Compatibility: Fits standard damper shafts ranging from 6 mm to 16 mm, providing versatility across multiple brands and models.
• Maximum Extension: Adds 170 mm (6.7 inches) of total length to bypass obstructions or insulation.
• Rugged Construction: Manufactured from corrosion-resistant galvanized steel for long-term industrial durability.
• Secure Mechanical Link: Designed to maintain actuator torque transmission (up to 6 Nm) without rotational play.
• Direct Fit: Optimized for Belimo LM, LF, and TF series actuators for rapid field installation.

What is the maximum torque rating for the Belimo AV6-20?
This extension is rated for use in applications generally requiring up to 6 Nm of torque, which covers most small to mid-sized damper actuators like the LF and LM series.

Can the AV6-20 be used on non-Belimo actuators?
Yes, as long as the actuator's universal clamp or shaft coupler accommodates a 10 mm diameter extension rod, it can be used across various manufacturer platforms.

Is this extension suitable for round or square shafts?
The AV6-20 is designed to clamp onto round shafts between 6 mm and 16 mm. The extension rod itself is a 10 mm round profile that the actuator then grips.
