Sandia SAFE 128 Cooling Fan | 22-31 VDC, Axial, Fault Detection



Sandia SAFE 128 Cooling Fan is an axial fan specifically designed to attach to the cooling port of avionics units directly. This innovative fan offers a nominal cooling air capacity of 20 CFM (no load). It operates efficiently, ensuring proper cooling for the avionics equipment.

One notable feature of the SAFE 128 is its alert output system. It is equipped with a mechanism that triggers an alert whenever the fan's RPM (rotations per minute) falls below a pre-set level. This functionality serves as a valuable indicator for monitoring the fan's performance and promptly addressing any potential issues.

By providing effective cooling and incorporating an alert output system, the Sandia SAFE 128 offers enhanced reliability and performance for avionics units.
