Head harness(inside hood)

Breathing hose

Connector(nipple)

How does it work?• A continuous flow of clean air is

fed into the hood from a remote source (compressor, pump)

• Air flows out through the exhalation valve

• Contaminated outside air cannot get into the hood due to the higher air pressure inside
