Built-in Vacuum Sensor VS Micron Gauge: Due to the different
placements of vacuum sensors, the vacuum reading of the pump may vary with the micron gauge which is connected to the system. The
airflow is not the same at different placements in the system when
vacuuming. The air density is larger which is far away from the
pump, so the readings of vacuum are high.
Oil Mist Notes:
When starting vacuuming, the pressure is relatively high, the air
outlet is large. The vacuum pump has a large exhaust volume. So
there will be oil mist overflowing with gas. This is a common
feature of rotary vane vacuum pumps. Oil mist appears at first
which is a normal phenomenon. When the vacuum drops to a very low
value, the exhausting volume is small and there will be no oil
mist. Therefore, the vacuum pump should regularly inspect the oil
level to avoid running out of oil.
