Belimo NFBUP Spring Return Damper Actuator in-lb On/Off - 90 24/120/240VAC

The Belimo NFBUP is a versatile spring return damper actuator designed for commercial HVAC applications requiring reliable on/off control. This actuator delivers 90 inch-pounds of torque and operates on multi-voltage power supply (24VAC, 120VAC, or 240VAC), making it adaptable to various control system configurations.

Key Features:

• 90 inch-pounds of torque for driving medium to large dampers
• Spring return operation ensures fail-safe positioning during power loss
• Multi-voltage capability (24/120/240VAC) for flexible installation
• On/Off control for simple two-position damper operation
• Direct replacement for NF120 US model
• Durable construction for long service life in commercial environments
• 90-degree rotation for standard damper applications

The NFBUP actuator is ideal for controlling fresh air intake dampers, exhaust dampers, and zone dampers in commercial buildings. The spring return mechanism automatically returns the damper to its fail-safe position when power is removed, providing critical safety functionality for fire/smoke damper applications and ensuring proper building ventilation during power outages.
