Ultra High Airflow Performance DC Axial Fans

Mechatronics ultra-high RPM DC axial fans are ideal for applications where maximum airflow and static pressure is required. These ultra-high performance fan models feature reinforced fixed vane frame designs that increase static pressure. High precision balanced impellers rotate at nearly double the standard speed and push extremely high air volumes. Available in 12, 24, and 48VDC models for both 40x40x28mm and 120x120x38mm sizes.


  • 200%+ Increased airflow and static pressure over standard DC models
  • Tachometer output and PWM speed control function included on standard configurations
  • Environmental protection options available including parylene and conformal coatings

  • Robotics
  • Automation
  • Rack mountable servers
  • Networking equipment
  • Medical devices
  • Food service equipment


MR4028W-S       40x40x28             up to 28000 RPM and 32 CFM

MS1238E-T          120x120x38         up to 12000 RPM and 308 CFM

DC Fans with Thermal Speed Control

Mechatronics DC Fans with thermal speed control enable the fan to automatically adjust RPM at set temperatures. For example, at 25 degrees C or less, the fan will operate at roughly half speed. This promotes high energy efficiency and the lower RPM reduces the noise significantly. At 35 degrees C or greater, the fan will operate at full speed. Between 25 and 35 degrees C, the fan speed will automatically adjust based on the ambient temperature. Choose between hub mount or remote mount thermistor to best suit your application needs.


  • Automatically adjusts RPM based on temperature
  • Hub or remote mount sensor
  • High energy efficiency and low noise when full speed is not needed
