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 certied
• 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.
