Probably the most reported problem with central vacuum systems – aside from failure over time from corrosion – is the instability of the vacuum supply. Each user’s demand often causes pressure spikes and dips in the vacuum received by other users. Somewhat less noticed, but of probably greater impact, is the risk of cross-contamination through [...]

A number of factors need to be considered to properly size and specify a vacuum pump. In some of our previous posts, we've discussed topics like how to determine the right flow rate for your new pump. Considerations such as this are readily evaluated through the use of calculators such as those we have posted on [...]
BSL3 or Biosafety level 3 labs are specialized labs working with highly communicable and pathogenic microbes often transmissible by way of inhalation.[1] These labs can be found in clinical, diagnostic, teaching, research, or production facilities.[2] Recently, a local vacuum network was installed in the Boston area for a BSL 3 laboratory suite. The project was a [...]
