Forge Vacuum Chambers & Pumps



Our BHO Hardware stainless steel vacuum chambers are a perfect entry level product to enable an efficient and effective degassing process.

This exclusive, functional and practical range of stainless steel vacuum chambers are a perfect solution for a wide range of degassing scenarios.

Each chamber is supplied with a 3-foot hose which connects directly to a vacuum pump.

The high quality 304 stainless steel allows these chambers to be used thousands of times without losing performance.

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.

The chamber lid is manufactured from varying sizes of thick crystal clear acrylic and features an isolated vacuum gauge along with two 1/8"" BSP ball valves - one is used to connect the chamber to the vacuum pump and the second is used to evacuate the vacuum after degassing.

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.
