Cyclone 21 Compact Cooling Fan

Cyclone 21 Compact Cooling Fan

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 of forced air cooling to a variety of avionics equipment.  The fan motor design incorporates a precision high tier ball bearing capable of producing a 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 DO160D 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 FFW System, Fan Failure Warning System.  See table below for ordering instructions for a Cyclone-21 Blower with a TACH output as well as our FFW, Fan failure Warning system and control module for a second emote fan.
