The AF series are the most effective air powered fans available.  Complete with their own filter, gauge, and oilerm they have everything you need for lots of air movement without a lot of air usage.  The efficient design of these fans includes Super Vac's patented propeller which produces a much greater intake of air into the vacuum side, eliminates turbulence at the tips, and provides a high velocity screw action that sweeps air back over the motor.
