● Set pressure drops ... to achieve energy saving effect!

Set pressure of air compressor <br /> Minimum pressure required for equipment + pressure loss of piping, purifier (reference pressure difference) dryer, air filter, etc. Pressure loss of piping <br /> Pressure loss of straight pipe + pressure loss of valve + pressure loss of tee, elbow, etc.
Purifiers using dryers, air filters, etc. cause pressure loss.
... confirm again ...

Controlling pressure loss to a minimum is closely linked to reducing the set pressure of the air compressor.

● Running load rate ... increased to energy saving! Reduced power consumption
Specific power (kW / m3 / min) is the smallest at 100% load operation. If it is operated at low load, the power required to compress 1m3 air will increase.
The average power consumption per unit of air is the way of the oil screw type air compressor intake control valve ---------------------------

Specific power (kW / m3 / min)
{Reference input power = motor output power / motor efficiency Use this formula to calculate input power (estimated)}
◎ The power consumption of the air compressor will decrease at low load, but the power consumption per unit of air will increase during low load operation.

● Factory diagnosis. Know the following.
Operating load rate and consumption power of air compressor (specific power = kW / m3 / min)
No matter what type of air compressor is used, when 1m3 of air is compressed to the set pressure, the required power is 100% at the minimum when running at load. If it is running at low load, the power will increase.
