Ruskin's low leak CD50L damper when combined with the appropriate 24v linear actuator produces a damper/actuator assembly that provides linear airflow through damper with respect to the signal it receives. This will allow for easier test and balance as well as save energy for LEED EAc1 on the building envelope.
To learn more about the CD50L, please contact your local Ruskin Representative at www.RUSKIN.com.
Using Ruskin CD50 dampers in your LEED projects will help identify energy savings in the building envelope and throughout the ductwork. Airfoil blades reduce pressure drop and noise and the CD50 in Class 1 leakage rated that meets requirements of IECC and ASHRAE 90.1 by leaking less than 3 cfm/sq. ft. at 1" static pressure.

Using Ruskin CD60 galvanized steel dampers in your LEED projects will help identify energy savings in the building envelope and throughout the ductwork. Airfoil blades reduce pressure drop and noise and the CD60 is Class 1 leakage rated meeting the requirements of IECC and ASHRAE 90.1 by leaking less than 3 cfm/sq. ft. at 1" of static pressure.

AMCA’s Inmotion magazine supplements highlight important industry issues and key solutions to today’s HVAC problems. In the Fall 2007 issue, Ruskin Vice President of Sales and Marketing, John Knapp, explains why in his article Damper Leakage Rates - More Important than Ever!
According to Knapp, “All HVAC dampers, i.e., control, backdraft, fire, smoke, and combination fire/smoke, contribute to the overall efficiency of the air system. With the emphasis on “green,” sustainable buildings, IAQ, and energy savings, damper leakage rates are more important than ever. Every CFM counts!”
In this issue of AMCA Inmotion, you’ll also learn:
- The two main locations for potential damper leakage and how to design for them.
- How damper leakage is a function of pressure, not airflow.
- How AMCA’s Certified Ratings Program (CRP) ensures damper performance every time.
- About AMCA’s Certified Leakage for Smoke and Combination Fire/Smoke Dampers.
Ruskin Manufacturing, Kansas City, MO, announces the [model:13474]CDTI-50[/model] Thermally Isolated Aluminum Control Damper. This damper is specifically engineered and manufactured to provide the lowest thermal conductivity available. Each airfoil blade is injected with high-density polyurethane foam providing thermal isolation. After the injection process, each blade edge is then cut producing the thermal break needed to effectively isolate one skin from the other reducing thermal transfer.
The CDTI-50 has been tested by an independent lab to ASTM C976-90 & ASTM C1199-97 standards for Thermal Performance of Building Assemblies and Thermal Transmission. The CDTI-50 is leakage controlled to as little as 4cfm per square foot with only 40 inch lbs. of holding torque.
Ruskin builds a complete line of commercial and industrial control dampers, fire/smoke dampers, louvers and grilles for the HVAC and architectural market.
