Excl. Tax: £220.79 £264.95

Our 7L acrylic vacuum chambers are a robust option for those who want to see inside from the sides to monitor the purging/'muffin' process. They're not advisable to use with a heat mat for obvious reasons. There is a hard-wearing rubber seal around the lip.

Each acrylic chamber comes with a glycerin-filled pressure gauge which goes as low as -30PSI. There is an inlet filter attached so that when you're pulling air in there is no debris entering the chamber.

All vacuum chambers are tested and signed off by the BHO Hardware engineering and quality control department before being dispatched to customers. All BHO Hardware chambers come with a 2-year guarantee.

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.
