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.
A plenum chamber is a chamber that operates at a positive pressure  and is filled with fluid or air. It is used to increase air flow in  enclosed spaces. The positive pressu â¦ re draws air from the space  into channels, which causes air movement.he pumping chambers are the lower two chambers, the ventricles. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the body through the aorta â¦ . The ventricles are the pumping chambers'.
