How to replace oil & filter on the GVS 40A vacuum pump
Regularly changing the oil and filter on your vacuum pump will help keep it running well for years to come. On this page we will walk you through how to change the oil and filter on all Atlas Copco GVS 40A vacuum pump variants. We recommend using this tutorial in combination with the instruction manual (6996022430).
Before you begin any service on your vacuum pump, make sure to take proper safety precautions. Switch off the electrical supply to the vacuum pump and let the system cool to a safe temperature. This will take approximately 1 hour.
Why is regular oil and filter replacements critical for your vacuum pump?
Regular oil and filter changes are essential to maintaining optimal performance and preventing unplanned downtime. Using genuine oil not only removes harmful build-up but also prepares your equipment for its next sprint.
Our premium vacuum pump oil provides top-tier lubrication, sealing, cooling, and oxidation protection—but these properties degrade over time. That’s why our recommended service intervals are designed to maximize pump availability in the most cost-effective way, helping you avoid costly damage from internal friction, thermal stress, and leaks.
Stay ahead of maintenance and keep your operations running smoothly while decreasing the majority of risk at a low cost.
