A plenum chamber is a pressurised housing containing a gas or fluid (typically air) at positive pressure (pressure higher than surroundings).hese gave rise to the notion of 17th century 'plenum' as the opposite of vacuum, and all things being either Plenum or Vacuum. By the 19th century, the development of mechanical fans and industrial machinery had provided another, more technical use.
