The Cyclone-21 is a 3 port avionics cooling fan design to cool up to (3) individual pieces of equipment, i.e. GPS, main radio, backup radio, flat screen, transponder, audio and or other electronics equipment. Installing a cooling fan will decrease high temperatures from avionics electronics so equipment can function with integrity and operate to recommended life expectancy.
The blower produces 21 cubic feet per minute (CFM) of forced air cooling to a variety of avionics equipment. The fan motor design incorporates a precision high tier ball bearing capable of producing balanced, high speed RPM’s at 100% duty cycle.
The Cyclone-21 dc brush-less motor is a custom design that incorporates circuit protection including locked rotor, over current, low, high voltage input as well as a high speed winding and con-formal coating. The Cyclone-21 has the smallest footprint, (3 x 3 x 1 in) and highest output for an FAA approved avionics blower for 14/28 volt aircraft systems.
The Cyclone blower was DO-160D tested and FAA-PMA approved and has 25+ years of reliability in the field. The Cyclone-21 is the number one choice for OEM and aftermarket sales world-wide for many make and model aircraft and rotor-craft as well as military and other ruggedized vehicles. The Cyclone-21 has been used by Airbus, Boeing, general aviation OEM’s, rotor-craft as well as military vehicles.
The Cyclone-21 DC motor has a third wire for tach output compatible with our LS03-02072 Fan Failure Warning System. See table below for ordering instructions for a Cyclone-21 Blower with a tach output as well as our Fan failure Warning System and control module for a second remote fan.
