NSPRD024-8 - 8" Spring Return Round Damper Mid-Torque


The new DuroZone round spring return dampers NSPRD024 and SPRD110 series, can be configured for either spring OPEN or spring CLOSED operation. For example: Spring-Return OPEN means that when the power is off, the damper OPENS. DuroZone "Mid-Torque" spring-return round dampers come in sizes from 4 to 20 inches in diameter with a 24 volt motor.

NSPRD Series Features:
  • Gasketing included for high integrity seal
  • Single set screw secures motor
  • DuroZone "Mid-Torque" Spring Return Motor
Note: The DuroZone round spring return dampers with the new Mid-Torque motors are designed for fresh air intake. Although we recommend the RD, MB and MS series for zoning, the NSPRD024 with a Mid-Torque motor configured spring OPEN can be used for zoning.
