The benders and cutters are manual (except a shear)old school.
There are 4 fans total.One for each halide and 2 for the canopy.One on the left side blowing in and the one in the rear is the exhaust.Just above the ballast is a speed control for the fans they move 110cfm at full rpm and the halides have the same control.Exhaust air will hit the wall behind the tank and blow over the ballast helping to keep thier temps down.
