Install through the register or plenum into an existing rectangular section of sheet metal. Remotely powered by air, the rectangular Flexdampersâ„¢ are not hindered by the presence of a bulky motor on the outside of the damper or on the inside of the damper to disrupt airflow.
Easily bent or folded, the rectangular Flexdamperâ„¢ is inserted through a register or other smaller opening, making this damper your only option for retrofitting air control into ducts that have been covered with sheet rock or other obstacles, eliminating sheet metal cutting.
Rectangular Flexdampersâ„¢ fit several sizes of duct, due to their "trim-to-fit" design. Simply measure the size of the duct and trim the blade and base of the rectangular Flexdamperâ„¢ to the correct size using scissors or a razor knife.
Specs for Round and Rectangular Flexdampersâ„¢
Rated Cycles: Average of 250,000 cycles, depending on environment
Temperature Range: 0° to 200° F intermittent, 0º to180º F continuous Inflation Pressure: 10 W.C. (Approx.1/3 PSI)
Leakage: 10% Average.
Static Pressure: Flexdampersâ„¢ are rated for static pressure to .5"
Pump: 110VAC with 24VAC interface. A single pump will handle most applications. Certain installations requiring automatic heat/cool changeover, or using multiple large Flexdampersâ„¢ will require faster actuation times--add a second pump if needed.
