spyder shutter with a 12 inch dye excel barrel, shocktech quick strip bolt, 32 degrees 6 stage expansion chamber,
this fan is great i never have to worry about my goggles fogging up. It is very quite and is not heavy at all. Very easy to install SNAP......SNAP..........SNAP its that easy an it keeps you cool in the hot weather.
the only bad thing is the people that say it is sooooo hard to install the people that say its hard to install have no idea what they are talking about. Because all your have to do is pop off the visor and snap the fan in than snap the visor back on and your done.
It is the greatest thing to happen to paintball masks I recommend that anybody who plays paintball should get one of these fans WELL WORTH THE MONEY!
