Technical Parameter

Notes: Above 60,000 microns, vacuum value is not shown and the screen shows --. The waiting time for the vacuum reading is longer for a large system.

Product Comparision Chart

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.
