  • Industry-Leading Belimo Motor: Equipped with the Belimo LM24-3-T Power Open/Power Close 3-wire motor, providing 45 in-lbs of torque—double the strength of comparable dampers. This motor is designed for efficiency and reliability, offering precise airflow control while using less power than traditional spring return dampers.
  • Energy Efficient: This damper uses only 2VA of power for a 90-second opening and closing cycle, compared to 8-10VA used by spring return motors. One 40VA 24VAC transformer can power 20 or more dampers, saving energy and reducing operating costs.
  • Works with Most Zone Control Systems and Thermostats: Compatible with almost any zone control system or thermostat, regardless of brand. Perfect for both new installations and retrofits.
  • Precise Motor Adjustments: The open/close motor adjustments allow fine-tuning of airflow to meet your specific needs. The damper blade will not move when de-energized, offering additional modulation flexibility.
  • Heavy Duty Construction: Built with heavy-duty galvanized metal and bronze bushings (not plastic), ensuring durability and long-term performance.
  • Minimal Leakage: Features Durozone duct-rated blade seals that provide near-zero leakage, enhancing system efficiency and performance.
  • Reinforced Strength: Reinforcing beads provide extra strength, while Durozone commercial 1/2” drive hardware ensures secure operation.
  • Easy Operation and Testing: Includes a de-clutch button on the motor for easy rotation of the blade during testing. The reversing switch on the motor allows for easy direction change of the damper blade.
  • Long-Lasting: With its robust construction and top-tier motor, this damper is designed for long-term, trouble-free operation.
  • 5-Year Warranty: Backed by RetroZone's industry-leading 5-year warranty, ensuring peace of mind for years to come.
