KMC Controls VTD-1405 Damper Crankarm

The KMC Controls VTD-1405 is a high-performance 1/2 inch damper crankarm designed for heavy-duty commercial HVAC applications. Featuring a long-slot design, this crankarm provides the extended leverage and mechanical advantage required for precise pneumatic actuator linkage and damper positioning. Engineered by KMC Controls, it is constructed from high-quality cold-rolled steel (CRS) with a protective zinc and dichromate finish to resist corrosion in demanding environments. This HVAC damper accessory facilitates a secure connection between 1/2" diameter shafts and actuator linkages, ensuring smooth linear-to-rotary motion conversion. Whether you are performing a VAV terminal unit repair or a new damper installation, the VTD-1405 is the industry-standard component for maintaining reliable airflow control. Its robust build supports high-torque requirements while minimizing mechanical play, making it a critical part of any automated building control system.

• Long-slot design allows for adjustable linkage positioning to fine-tune stroke and torque.
• Zinc-dichromate plated steel construction ensures maximum durability against oxidation.
• Compatible with standard 1/2" damper shafts commonly found in VAV and AHU systems.
• Optimized for use with KMC pneumatic actuators and various universal HVAC linkages.
• Provides precise damper blade modulation for improved energy efficiency and climate control.

What is the shaft size compatibility for the VTD-1405?
The KMC VTD-1405 is specifically engineered to fit standard 1/2-inch diameter damper shafts.

Does this crankarm work with non-KMC actuators?
Yes, while designed for KMC Controls equipment, it is a universal slotted crankarm compatible with most industrial 1/2" shaft linkages.

What is the advantage of the 'Long' crankarm version?
The extended length provides a wider range of motion and greater leverage, which is essential for certain damper linkage configurations requiring specific torque levels.
