Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line breathing (hard-helmet diving), respiratory equipment used on ground for escaping from toxic atmospheres and for working in contaminated atmospheres. It also covers breathing gas for hyperbaric operations and synthetic air. While EN 12021 does not cover aerospace applications, the British MOD publication DEF STAN 68-284 and its counterparts in other countries cover also the breathing gases used in aviation.

Grinding & Deburring dusts are Unbreathable. Many industrial processes generate contaminants in the air in the form of dust and particles. Airborne dust and fine particulate can be hazardous to human health, and should be extracted before it reaches the worker`s breathing zone.? Typical sources of these pollutants arise from cutting, grinding using an angle grinder or die grinder, automated grinding machines, deburring work and many other abrasive processes. Robotic grinding machines generally create a large volume of particulate which can require more filtration media to handle increased dust loads. Whereas other applications such as deburring can create very fine submicron particles that require the use of a high efficiency HEPA filter to capture the fines.? Metal, composite, fiberglass and rubber dust can be extremely dangerous to inhale and can be associated with many different lung conditions and health problems. Diversitech offers a diverse range of dust collectors, extraction arms, filter cleaning machines and downdraft tables for your grinding dust filtration requirements.???
