GNP/GAP Series

GNP/GAP Series Spring Return and

Non-Spring Return Electronic Damper Actuator.

Description

Designed for control of critical environments the OpenAir
direct-coupled fail safe/fail-in-place electronic actuators

are available in modulating, two-position, and oating

control of laboratory fume hoods, supply and exhaust
units.

Features

• Fast operation, 2 seconds runtime

• One model performs all control signals:

– 2-position

– Floating

– Modulating (0 (2) to 10 Vdc and 4 (0) to 20 mA)

• 24 Vac/dc compatible

• Selectable fail-safe position (fail open or closed)

• Feedback standard on all models

• Highly accurate positioning

• Self centering

• Unique self-centering shaft coupling

• Assembled in the U.S.A.

• Plenum rated

• UL and cUL listed, CE certied

• Manual Override

• Precabled

Applications

Used in laboratory fume hoods, constant or variable air
volume installations for the control of supply and exhaust
air terminals; 53 lb-in (6 Nm) torque.

Models designed for applications that require the damper
to return to a fail-safe position when there is a power
failure; or models for fail-in-place.
