Customers can buy oil close to the above specifications locally. If he can’t buy them, please contact our company. Our company can export vacuum pump oil, oil in stock, complete MSDS and safe transportation appraisal.

Take the oil window of H-150 as an example, see the following two windows of H-150 where oil can be seen

Figure 1 The long oil window is the oil level indicator, and the oil needs to be added to the half position

Figure 2 The round oil window is the filter screen of the oil return port of the pump cavity. It is at the lower position of the pump and it is generally full . It is used to observe the oil product. If you see the oil is black or there are many impurities from this window, please replace the oil.
