jd diesel sullair increase pressure

Hi, Sometimes this is possible by changing the ratio of the gears. Or of the pulleys if it is a belt-driven machine. The element will run slower, so the capacity is reduced, but the maximum pressure is increased. The load for the JD engine stays the same. But, this is very specific for every make and model. Sometimes it's possible, sometimes it's not. So it really depends.. I don't know for this. Maybe you could contact Sullair and aks about this. Good luck! Cas
