Model URD & RSD Round Dampers
Model URD and RSD are round, single blade dampers
with a shutoff seal that gives the damper a 98% closure.
The motor for the URD has no moving switches or parts
to burn out. The actuator possesses 18 in. lbs. of torque,
manual gear release and powered open/powered close
operations. The URD features “fail safe” LED’s that will
indicate the position of the blade without the need to cut
holes or remove the damper from the ductwork.
The positional LED’s will only illuminate when the blade
is in the full open or full closed position. The RSD is a
spring return motor. The damper is field reversible from
power closed/spring open to power open/spring closed. The
motor posesses 3" lbs. of torque. The 18" and 20" RSD’s
have a motor with 18" lbs. of torque.

The Retrofit Solution
The SID (Slip-In-Damper) is the most user friendly
retrofit damper available. The 1.5VA actuator allows
up to 20 SID’s on one EWC Controls zone panel
with a 40va transformer. With a single cut the SID
can be installed in seconds. The optional S1A (see
page 17) end switch allows for increased flexibility.
