Adjustment of the Filling Screw
Cylinder Pressure Cycle
Adjusting the screw to regulate the flow of air optimises the time taken to pressurise depending on the air volume to be refilled and the system requirements.
When the downstream pressure reaches 2/3 of the supply pressure, full flow is automatically established
To adjust: – immobilise the piston using a spanner – adjust the screw with an Allen key • 1.5 mm key for 8 mm diameter • 2.5 mm key for 10 and 12 mm diameter
