We have modified the standard turbine 4-hole system by removing the water bottle (never use water for the bench exam) and rerouting the air system. Additionally, the proper connection pieces for the compressor have been fitted to the intake hose using the 1/4 M and 1/4 F hose barb and compressor quick disconnect. Each system is then tested before shipment. We recommend the California Air Tools 1.0 Gal. Light and Quiet Air Compressor, Model 1P1060SP. Available on Amazon and most hardware stores.
NOTE: You must adjust the outgoing pressure to 80 psi. When connected to the turbine unit, set the turbine pressure to 3-3.5 Bar.
