NAFA SERIESSPRING RETURN DAMPER ACTUATOR2 Point Spring Return Control20 NmNAFA.20S (T) SERIESNAFA series Spring Return actuators are developed for general air damper application, rotaryvalve and other devices which require a fail-safe function. During normal operation, the actuatormotorized the device. In the event of power outage, the actuator springs back to its original position.PRODUCT FEATURE Torque 20 Nm Damper size 4.0 m² Power supply AC/DC 24V and AC 230 V Shaft dimensions - Form fit 12 mm square Selectable direction of rotation Actuator with 1 m cable connection 2 Fixed auxiliary switches (SPDT) Manual Over-ride by crank handle when required Thermal sensor option availableMODEL SELECTION TABLEMODEL /TYPETORQUEPOWERSUPPLYNAFA 1-2020 NmAC/DC 24 V 10%NAFA 1-20S20 NmAC/DC 24 V 10%NAFA 2-2020 NmAC 230 V 10%NAFA 2-20S20 NmAC 230 V 10% NenutecRUNNING TIME110.140 sec(Spring Back 30 sec)110.140 sec(Spring Back 30 sec)110.140 sec(Spring Back 30 sec)110.140 sec(Spring Back 30 sec)AUXILIARY SWITCHES2 x SPDT(Fixed & Adjustable)2 x SPDT(Fixed & Adjustable)1

THERMAL SENSOR NTS72Thermal Sensor NTS 72 consist of both Ambient (TS1) and Duct sensor (TS2). TS1 will trip open when the ambient temperature rise above 72 . TS2 will trip open when the duct temperature rise above 72 .9565Ø9522852INSTALLATION / MOUNTING INSTRUCTIONIMPORTANT REMARKFor special requirement, consult your local Nenutec’s representative.This actuator includes electrical and electronic components and may not be disposed as household garbage. Please consider the local valid legislation.AC / DC 24 V:AC 230 V:Connect via safety isolating transformer.To isolate from the main power supply, the system must incorporate a device which disconnects the phase conductor (with at least a 3mm contact gap.)The performance specifications are nominal and conform to acceptable industry standards. NENUTEC shall not be liable for damages resulting from misapplication or misuse of its products.NAFA SERIES SPRING RETURN DAMPER ACTUATOR 2 POINT SPRING RETURN CONTROL 20Nm4
