Note: (1) The lubricating oil is No. 100 vacuum pump oil. (2) The cooling water flow rate in the table is the amount of inlet water at 20°C, and the flow rate will change when the inlet water temperature is different. (3) The noise level is measured indoors when the exhaust port is open, and it will be reduced by 5-10dB (A) when connected to the outdoors. |
