Tips: How to adjust air compressor switch?
- One is that the pressure difference is fixed by the switch itself, and only the automatic shutdown pressure is adjusted. This kind of switch has two knobs adjusted by a flat-head screwdriver on the switch. The two knobs must be adjusted in unison, otherwise they will stop when they start together, and start again when they stop.
- The other one is to adjust the starting pressure (low pressure) and the other to adjust the stop pressure (high pressure).
- Air compressor pressure adjustment: Turn the pressure adjustment screw clockwise to increase the closing and disconnecting pressure synchronously. Turn the pressure adjustment screw counterclockwise, the closing and opening pressures decrease synchronously.
- Pressure difference adjustment: Turn the pressure difference adjustment screw clockwise, the closing pressure remains unchanged, and the breaking pressure increases. Turn the differential pressure adjustment screw counterclockwise, the closing pressure remains unchanged, and the opening pressure decreases.
