Low Torque Applications
GND Series 53 lb.-in. torque
FEATURE | FUNCTION | BENEFIT |
|---|
53 lb.-in (6Nm) of power in small footprint | More torque in a smaller package size | Easily fits into applications and delivers the required force |
Two-position control available in 24Vac/dc, 120 Vac, 230 Vac | Multiple power options | Reduces the need for additional transformers – uses the power that is available in the area |
UL, cUL, CE, C-tick ratings | Meets global agency approval standards | Product certified for use anywhere in the world |
Designed to meets UL555S standards: 350ºF operation ½ hour | Designed to Agency standards | Meets Building and Fire Codes |
15 second drive/spring return operation | Fast acting | Reliable and responsive reaction provides safety and performance |
No special cycling required during long-term hold | Typical operation is to hold open the damper until an event | Provides long-term safe and reliable operation in hold mode without the need to cycle damper |
Built-in auxiliary switches fixed at 5º and 85º | Provides position indication - open/closed | Eliminates the need for accessories Provides “proofs” for system assurance of operation |
EFL models pre-cabled, quick connect to heat responsive devices, available in 165ºF, 212ºF, 250ºF and 350ºF | Cuts power to the actuator and closes the damper when temperatures reach the designed levels | Ensures the damper is closed during an event |
Designed for ½" round damper shafts | Form fit to ½” damper shafts | Provides a safe and reliable connection to combination fire and smoke dampers that typically use ½” shafts |
High Torque Applications
