The Air Clamp Control Kit comes with an air switch to extend and retract the cylinder piston and a flow control valve to adjust the rate the air cylinder piston moves. A brass muffler softens the sound from the exhaust port. We also include a simple mounting bracket and hardware to locate your controller on the PantoRouter® table or you could screw it to your bench. The kit comes with 5ft of air tubing and an ⅛” pipe thread fitting to connect to your compressed air system (not shown).
