How to change the oil and filter on your Atlas Copco GVS 60 A vacuum pump

Regular maintenance helps keep your vacuum pump running smoothly. On this page we will guide you through how to change the oil and filter on your Atlas Copco GVS 60 A vacuum pump (all variants). We recommend using this tutorial alongside the instruction manual (6996022430) for this pump.

Before beginning any service on your vacuum pump, make sure to unplug it and let it cool to a handleable temperature.

Over time vacuum oil can become contaminated with particles and moisture, reducing its lubricating properties and causing increased wear on internal components. This can result in decreased pump efficiency, higher operating temperatures, and potentially create costly pump damage. By changing the oil and the filter, you remove all harmful build-up from within the system and decreases majority of the risk at low cost.

Neglecting these maintenance tasks may affect the warranty on your vacuum pump. This means that any repairs or replacements needed due to improper maintenance would not be covered, potentially leading to significant out-of-pocket expenses. 

1. Strap wrench

2. Allen key set

3. 12mm spanner

1. Begin by reassembling the exhaust filter and flange. The filter threaded stud can only protrude a maximum of 1mm above the nut.
2. Now apply vacuum grease to the filter.
3. Lubricate the O-ring with vacuum grease and fit it back onto the vacuum pump.
4.  Insert the exhaust filter.
5. Use a 6mm Allen key and 23Nm of force to tighten the bolts and secure the exhaust flange in place.
6.  Apply oil to the oil filter and fit it back in the vacuum pump.
7.  Apply vacuum grease to the O-ring.
8.  Fit the oil drain plug back onto the pump using a 12mm Allen key.
9.  Fill the vacuum pump back up with oil (approximately 1 to 1.5 L), or until the oil level reaches ‘max.’ This can be seen on the oil level sight glass.
10. Put the oil filler plug back on, using a 12mm Allen key. 

1. Begin by assembling the exhaust filter and flange. When assembling the filter and flange, make sure that the threaded stud of the filter does not protrude more than 1mm above the nut.
2. Now apply vacuum grease to the filter and the O-ring, and fit both back onto the vacuum pump.
3.  Insert the exhaust filter.
4.  Tighten the bolts with a 6mm Allen key and 23Nm of torque to assemble the exhaust flange.
5. Next, apply oil to the oil filter and insert it back into the vacuum pump.
6. Apply vacuum grease to the O-ring.
7. Fit the oil drain plug back into place using a 12mm Allen key.
8. Fill the pump back up with about 1 to 1.5 L, or until the oil level reaches ‘max.’ This can be seen on the oil sight level glass.
