Breathing Air System

Our bodies have a limited capacity to filter the air we breath. Anything much smaller than 10μm will travel past the nose and into the lungs. When contaminants reach the lungs, respiratory illness can occur, but when they hit the bloodstream they can be deadly.

 Carbon monoxide gas has no odor, taste, or color, but even in small concentrations it is quickly absorbed into the bloodstream. It has a detrimental effect on coordination, reaction time, and visual acuity, subjecting even the most safety conscious worker to accidents. In higher concentrations, it is lethal.

The KBS is a complete purification system designed to remove excessive moisture, solid particles, oil and oil vapor, and carbon monoxide from ordinary compressed air. The OSHA Grade D air it produces can efficiently feed face masks, hoods, and other breathing devices to protect worker health and safety.
