context_page_description: An air compressor is a device that converts power into potential energy stored in pressurized air. By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank.
  An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.
context_section_description: To ensure all compressor types run efficiently with no leaks, it is imperative to perform routine maintenance, such as monitoring and replacing air compressor fittings. It is suggested that air compressor owners perform daily inspections of their equipment, such as:
  Checking for oil and air leaks
  Checking the differential pressure in the compressed air filter
  Determining whether or not the oil in the compressor should be changed
  Verifying safe operating temperature
  Draining condensation from air receiver tanks
