Supplied Air Systems
High Pressure (plant air) Low Pressure (ambient air pump)
You can filter and regulate your plant air to deliver clean air to workers.
  • Gives the worker many configurations of headgear, regulators and hoses
  • Allows the worker to heat or cool the air by as much as 50 degrees
  • Is regulated at 25 to 125 psi
Low pressure pumps can be used to deliver air — similar to high pressure — to the worker. The primary difference is that low pressure pumps are designed to be portable and normally run one to two workers without cooling or heating options. They are appropriate when plant air is not available. Low pressure respirators typically require 4 to 17 psi.
