For use with our oil extraction equipment, chambers and ovens. If you want to connect the pump to a vacuum oven you'll need a connector hose with the right connections, available on our website. 

Using the pump with a chamber
We recommend a maximum of 15-20 minutes to run the pump and pull a deep vacuum It should take 10 minutes to pull the vacuum and then leave the pump running for another 10 minutes. After this initial pull you should see the vacuum drop as this is when most of the degassing occurs. The vacuum can be maintained for up to 100 hours or longer but the pump itself isn’t run continuously. Periodically let air in to your chamber to burst any bubbles and then pull the vacuum again, using the pump for another maximum of 20 minutes. This can be repeated intermittently and you can also flip your material as part of the degassing process. 

When using a vacuum pump with the chamber always ensure there is oil in the pump and that it is clean and changed regularly. 
Allow the pump cool between uses and don’t have it running for prolonged periods of time.
Afterwards, ensure the pump and chamber valves are turned off in the reverse order of how you turned them on and disconnect the hose. Otherwise you may pull oil from the pump into the chamber.
