DIY Vacuum Pump And Chamber — by ‘Black Beard Projects’. You can test if your vacuum pump and chamber work perfectly by putting a glass of water inside the steel pot. If the bubbles are present, then this means that air is being produced because of the low pressure inside the chamber. Depending on the type of fridge compressor, you may be able to produce a vacuum environment of around -685 mmHg.
