Technology that Saves Lives

Belimo fire and smoke damper actuators are designed for operation in smoke and combination fire and smoke dampers in ventilation and air-conditioning systems with a torque range from 18 in-lbs to 180 in-lbs @ 350°F. For maximum safety in all situations, the fire and smoke actuators meets all codes for commercial buildings in the U.S., passes UL 555 & UL 555S at 350ºF and tested for 30,000 open-closed cycles with approved dampers. Belimo fire and smoke damper actuators exceeds UL’s requirement of 20,000 cycles at damper static load.

Increased Efficiency

Safety in Buildings

Belimo fire and smoke damper actuators have an extensive torque range specifically designed for operation with fire, smoke, and combination fire and smoke dampers in ventilation and air-conditioning systems. As an integral part of the life safety system, Belimo fire and smoke actuators provide high perfor­mance, low power consumption, and are compliant with Life Safety Codes and Standards.

Free Online Learning of Life Safety Codes and Standards that Govern Fire Dampers

Although life safety codes govern the testing, repair, and replacement of actuated dampers, deferred maintenance is a chronic problem. Many defective life safety dampers remain in the system, inoperable, without knowledge of failures or dampers fastened open. As buildings age and systems degrade, more fires will occur. The number one failure point on old dampers is the actuator.

Take this free online training and learn:

  1. The codes and standards that govern damper actuators
  2. Common types of dampers
  3. Replacement processes, and additional information on retrofit solutions.
    This training takes approximately 30 minutes to complete. You will be able to test your knowledge throughout the training and take a quiz at the end.

Consulting Engineers

Your analytical skillset makes you an invaluable asset to your organization and though your job is to design systems and operating sequences that meet energy codes to make facilities run more efficiently. You constantly find yourself collecting information and analyzing data when it could be spent looking for new and innovative ways to save energy and improve building performance. Belimo fire and smoke damper actuators offer:

  • Internal, heat-resistant spring closes damper without loss of torque at elevated temperatures
  • Modulating model positioned remotely to provide fire, smoke, and air balancing function is economical in space saving applications such as economizers, stairwells, and barrier walls
  • Electronic or microcontroller based motor that cuts off at full open position to save energy with less noise.
  • Considerably exceed legal requirements
  • Higher efficiency with lower power consumption avoids carbon emissions over the life of the building
  • Customer focused organization with support documentation requirements for plans and specifications along with comprehensive retrofit solutions to increase system efficiency

Contractors & Distributors

You need to run a lean and mean operation—however, finding new and effective ways to provide unique solutions to client problems are key to achieving the ultimate goal of increasing profits and growing your business. You feel like far too much of your time is spent diagnosing technical issues and troubleshooting problems for others when it should be spent getting the job done and moving on to the next one. Fail-safe damper actuators provide:

  • Universal clamp fits different shaft sizes to help reduce inventory
  • Clockwise or counter clockwise fail-safe rotation accomadates installation requirements for fail open or fail closed damper position
  • Accessible manual override button to help you pre-tension damper blades quickly
  • Direction of rotation switch allows the actuator travel to match the control signal output
  • Simple, direct coupling reduces labor costs
  • Mechanical end stops to adjust the angle of rotation for added installation flexibility

Building Owners

Building expansion and tenant improvements are a constant challenge to your facility department and the value of your property. You are having difficulty keeping clients comfortable, identifying ways to optimize your HVAC system, and preserving capital budgets. Fail-safe actuators offer:

  • Showcase your building by utilizing energy efficient products and enhance your ENERGY STAR® certification
  • Electronically protected against overload increases actuator longevity and reducers maintenance cost
  • Low power consumption actuators reduce utility cost
  • Quiet operation with brushless DC motor keeps office spaces aquistically comfortable
  • Reliable and precise actuator positioning for  ventilation dampers meets code requirements and keeps occupants comfortable

Facility Managers

Higher energy prices combined with costly building inefficiencies are making your job more and more difficult to perform. While you should be looking for new and innovative ways to reduce energy consumption and improve facility performance, you’re simply too busy dealing with employees, troubleshooting technical issues, and trying to combat costly problems with more money. Fail-safe damper actuators can:

  • Guarantee minimum torque over entire specified operating range with no loss in performance due to temperature, supply voltage or speed
  • Clockwise or counterclockwise fail-safe rotation accomadates tennant improvement of retrofit installation requirements for fail open or fail closed damper position
  • Provide reliable operation and occupant comfort with increase building performance
  • Easy installation for tenant improvement projects
  • Online technical support and local inventory from controls distributors makes replacement of any damper actuator fast and easy


You are tasked with communicating to organizations how they can save energy and improve performance — but key opportunities are passing by you. Why? Most of your time is spent searching for new product innovations that are backed by proven and reliable energy savings data. Belimo’s fire and smoke damper actuators offer:

  • Higher efficiency with lower power consumption saves energy cost
  • Minimum torque guaranteed over entire specified operating range; no loss in performance due to temperature, supply voltage or speed
  • Electronic or microcontroller based motor that cuts off at full open position to save energy with less noise.
  • Electronically protected against overload decreases maintenance cost
