Information About CDR25

The CDR25 is a round galvanized damper designed as part of Ruskin’s heavy-duty damper lineup for high-performance HVAC control. It features flat-blade construction that provides stable operation and helps maintain accurate airflow modulation under varying system conditions. The damper is compatible with standard HVAC ducting interfaces, allowing seamless integration with existing mechanical and control systems across commercial or industrial installations. Engineered to manage elevated airspeeds and pressure loads, the CDR25 is widely used in ventilation networks requiring dependable Class II leakage performance and consistent air management.

Key Features

  • Heavy-Duty Construction: built from galvanized steel with reinforced housing to support long-term use in demanding HVAC environments.
  • Flat-Blade Assembly: ensures controlled, even airflow modulation by minimizing turbulence and maintaining consistent resistance across the damper’s full operating range.
  • Class II Leakage Performance: meets established leakage standards that help maintain system efficiency and reduce unwanted air loss in controlled ventilation setups.
  • High-Velocity Operation: supports airflow speeds up to 4000 FPM, making it suitable for high-demand duct systems that require stable performance under elevated velocities.
  • High Static Pressure Rating: engineered to withstand up to 10" w.c. of static pressure, ensuring structural integrity in systems with significant pressure differentials.
  • Round Duct Integration: designed to fit directly into round ductwork, simplifying installation and reducing the need for transitional fittings or adapters.
  • Industrial Durability: corrosion-resistant galvanized materials and rugged construction contribute to long service life in both commercial and industrial HVAC environments.
  • Broad System Compatibility: adaptable for integration with control systems, mechanical components, and airflow regulation setups used across various facility types.

The CDR25 delivers the reliability and precision required for high-pressure and high-velocity airflow control in advanced HVAC systems.
