Fan Guns are much different than all other guns because they require electricity to power a fan and a hose with a spray/mist attachment. The hose sprays a mist, like the kind created from a spray bottle and fans propels the mist into the air to achieve the hang time. Fan guns have anywhere from 12 to 360 water nozzles on a ring that the fan blows through on the front of the gun. These banks can be shut on or off by valves. The valves are either manual, manual electric, or automatic electric (controlled by a computer).


Fan Gun Systems

  • Water pipelines, water hydrants, electrical distribution lines and electrical outlets are located on each trail
  • Water pumps and electric power distribution systems are in a permanent building, usually at bottom of the mountain
  • No air pipelines, air compressors, or air cooling systems are required
  • Fan guns have on-board air compressors, usually on wheeled carriages or towers
  • Systems can be manual or automatic

Fan Gun Advantages

  • Fan gun systems use less compressed air energy than air/water systems
  • Noise levels are lower than air/water systems

Fan Gun Disadvantages

  • Snow cats are required to move fan guns on the mountain because fan guns are heavy
  • Electrical distribution on the mountain is expensive due to high copper costs
  • Fan guns require colder temperatures than air/water guns

for operation

  • Snow inducer water injection additive is usually used for fan gun operation
  • Fan guns require fair amount of maintenance
