In vacuum technology, we divide pressure ranges between coarse vacuum, medium vacuum, high vacuum and ultra high vacuum.
Rough vacuum is probably the most widespread in:
• packaging
• transport
• food

The pressure range of rough vacuum ranges from atmospheric pressure (1013 mbar) to 1 mbar, that is, ~1 bar pressure difference from atmospheric pressure.
As with all different pressure ranges, in heavy vacuum there are a variety of applications and applications. The most common purposes are these:
• Keeping a product under vacuum (e.g. vacuum packaging)
• Filling a product with another pure gas (e.g. some food packaging)
• Make a leakproofness test of a product (only large leaks possible)
•Lifting a product from one place to another
• Create a pressure difference to move media in a closed system (for example: transport of granules and other solid media)

During rough vacuum, you still have a viscous flow, which means that all gas/media moves in the same direction, which makes it reliable and easy to work with.
Low2High Vacuum has a variety of products suitable for heavy vacuum, both oil-lubricated and dry alternatives. Feel free to look in our product catalog, if you do not find what you are looking for, please contact us as we do not have the opportunity to publish all products on the website.
