Supplied Air Respirators are designed to deliver clean air to the worker.
The air(*)> can be supplied from a high pressure compressor (breathable plant air), low-pressure pumps, or cylinders (bottled air). This clean air can be delivered to hoods, helmets, full facepieces, hanlf facepieces and loose - fitting face pieces.
Supplied air respirators offer many advantages over traditional respiratory protection such as :
Cooling or heating incoming air.
Fit testing only required on tighfitting facepieces
Low maintenance
Supplied air Systems are a good way to increase comfort, productivity and protection
*) Must be grade D or better.
High Pressure (Plant air)
You can fiter and regulate yor plant air with an air purification panel to deliver clean air to workers.
High Pressure
Give the worker many configurations of headgear, regulators, and hoses.
Allow the worker to heat or cool the air by as much as 50 degrees.
Is regulated at 25 to 125 psi
Low Pressure (ambient air pump)
Low pressure pumps can be used to deliver air-similiar 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
Cylinder (Bottled air)
This is another high pressure method of air delivery to a respirator. Cylinders are often used with pressure demand respirators. In continuous flow mode, the cylinders would be emptied very quickly. Cylinders are used when plant air is not available or for confined spaces with a backup escape bottle.
