Parts of a Compressed Air System – Where EXAIR Fits In

Founded as the American Society of Mechanical Engineers in 1880 in response to numerous steam boiler pressure vessel failures, ASME is now a multidisciplinary and global organization. ASME is one of the oldest standards developing organizations in the world, producing approximately 600 standards covering many technical areas, such as boiler components, elevators, measurement of fluid flow in closed conduits, cranes, hand tools, fasteners, and machine tools.

ASME has developed some information about compressed air, in ASME EA4 they divide a compressed air system into 3 sub-systems; Supply, Transmission, and Demand.

  1. Supply: conversion of primary energy resource to compressed air energy. … includes generation, treatment, primary storage, piping, controls, performance measurement equipment, and reporting systems.
  2. Transmission: movement of compressed air energy from where it is generated to where it is used…. includes distribution piping mainline and branch headers, piping drops, secondary storage, treatment, transmission controls, performance measurement equipment and reporting systems.
  3. Demand: the total of all compressed air consumers including productive end use and various forms of compressed air waste…. includes all end uses, point-of-use piping, secondary storage, treatment, point-of-use controls, performance measurement equipment, and reporting systems.

All three subsystems can be dealt with individually in order to produce efficiency gains within your own system. EXAIR is vital when focusing upon the DEMAND sub-system, specifically point of use. ASME defines the point of use as “where compressed air energy is converted to mechanical work or accomplishes a production related task.”

Why is EXAIR vital? Because EXAIR manufactures some of the most efficient point of use compressed air blow off products in the world. Too many production processes use open pipes, crimped nipples, drilled holes and other home-made contraptions to convert compressed air energy to mechanical work – these solutions are simply as inefficient, loud and potentially dangerous as it gets.

EXAIR’s engineered products focus on and improve the three features any home-made solution fails to completely address; air consumption efficiency, noise level safety , and outlet pressure safety. This family of blow off products includes our Super Air Knives, Super Air Amplifiers and Air Nozzles to mention a few.

The DEMAND sub-system of your compressed air system can provide some of the largest quantifiable improvement in your compressed air system. Don’t ignore those home-made solutions, let EXAIR assist you with retrofitting your current point of use applications and you will begin to see, and hear quick improvements.
