Depending on the number of workers to be served by the system and whether the system needs to be portable or a fixed plant system, the size and complexity of the system may change. However, the basic elements above must be present.
In order to properly size the breathing air system, it is absolutely essential that the user’s first decision is to decide the type and quantity of airline respirator(s) to be used.
A quick recap of the airline respirator types and their required flow and pressure requirements is essential.
All airline respirators are referred to by NIOSH as Type-C or Type-CE respirators.
NOTE: NIOSH approved CE respirators are designed for abrasive blasting, but they still require the same air flow as Type-C respirators.
