Glossary of Terms

Here is a glossary of terms related to central vacuum systems:

• Canister:
  The container that holds the vacuum dirt and debris collected by the system.
• Power unit:
  The central component that contains the motor, fan, and other components that drive the central
  vacuum system.
• Quiet operation:
  A feature of some central vacuum systems that reduces noise levels during operation.
• Air watts
  Central vacuum Systems air watts is a measurement that takes into account both the airflow (measured in CFM or CMH) and the water lift (measured in inches of mercury or H2O) of a central vacuum system. This calculation provides a comprehensive assessment of the system’s cleaning power and ability to remove dirt, debris, and allergens from a given space.
• Suction Power
  The residential central vacuum’s water lift, also known as water lift capacity, is a measure of the motor’s strength and suction power. It is usually measured in inches of water lift and indicates the ability of the vacuum to lift water through a hose or wand. A higher water lift rating typically means the vacuum has more powerful suction and can lift heavier debris and liquids.
