Series Description
The Belimo TFB, Belimo LF, Belimo NFB, Belimo AFB, and Belimo EFB Series direct-coupled air damper actuators provide control of dampers and valves for spring return applications. The damper actuators come in two-position, tri-state, proportional, and Multi-Function Technology (MFT) models. All include spring return to drive the damper or valve to a normal position when power is lost. Unique universal power supply models work with 24 Volt AC to 240 Volt AC or 24 Volt DC to 125 Volt DC. The new EFB Series is true spring return with a high 270 in-lb torque output and most models are available with optional NEMA 4 housing. It is possible to dual-mount EF actuators on one shaft, for a total of 540 in-lb. This actuator series is indispensable for Building Automation System BAS and HVAC applications.
