OpenAir™ Electric Damper Actuators

GDE/GLB Series
Non-spring Return Rotary
24 Vac - Modulating Control 0 to 10 Vdc

Description

Features

Application

The OpenAir direct coupled 24 Vac non-spring return rotary electri c actu ators are designed
for modulating control of dampers.

• Compact, lightweight design

• Self-adapting capability for maximum flexibility in damper positioning

• Manual override

• Offset and slope adjustment models available

• Independently adjustable dual auxiliary switches available

• cUL and UL listed;

These actuators are used in constant or variable air volume installations for control of HVAC
dampers requiring up to 44 lb-in (5 Nm) or 88 lb-in (10 Nm) of torque.
