Reducing air consumption

Reducing air consumption

Reducing air consumption

(OP)
You can reduce the amount of air consumed in a circuit by replacing the meter-out or meter-in flow control with a meter-in pressure regulator.

The fact there is a meter-out flow control indicates that there is more pressure and therefore more force available than is required to move the load.  This extra force is translated into acceleration and we add the flow control to cause an additional resistive load as a counterbalance.  However, we pay for the air based on the number of moecules we pack into the actuator.  By adding the meter-in pressure regulator, we reduce the amount of air that is stuffed into the actuator.

A 2.5" bore cylinder moving a 100 pound load at 4"/second and operating 24/7 could realize a cost reduction of about $100/year if the pressure to the cylinder were dropped from 87 psi to 52 psi.
