To provide the required level of protection to workers, employers must select appropriate supplied-air respirators and the proper supply of quality breathing air.
Although there are many so-called breathing
air filters available, few have the capability to
purify the airstream by removing carbon
monoxide and other common air line contaminants. Nomonox purifiers, however, combine
innovative, state-of-the-art design with basic
purification technology to produce high quality,
clean breathing-air. Special airborne contam-
inants-including particles, water vapor,
hydrocarbons, carbon monoxide and other
gaseous impurities-are eliminated.
Nomonox breathing-air purifiers meet the latest OSHA, NIOSH, EPA, National Fire Protection Association, and American National Standards Institute guidelines for the production of Grade D breathing air.
In addition, Nomonox purifiers
can produce air that meets the Nuclear Regulatory
Commission's Grade E requirement.
Nomonox Continuous Duty Purifier (CDP)
systems are made up of several purification
modules:
1. A Color Guard pre-filter that removes oil
mist and particulates from the air stream.
The filter material changes color to indicate
when the element needs replacement.
2. An adsorber with dual alternating desiccant
beds that capture moisture vapor and
contaminants. The desiccant beds are
continuously rejuvenated by a purge-air
regeneration process, which expels the
captured contaminants.
3. A blue moisture indicator that continuously
shows adsorber's effectiveness.
4. A catalytic converter that oxidizes carbon
monoxide to form carbon dioxide.
5. An activated carbon polisher that adsorbs
and removes unpleasant tastes, odors and
other organic compounds.
6. A particulate afferfilter that removes any
stray catalytic converter and/or activated
carbon assuring dust free air.
Also included with all CDP systems are the
following:
The Nomonox purifiers' control systems are factory set and calibrated. Once pressurized and energized, they begin to operate immediately. In the event of an electrical power failure in which compressed air continues to be avail- able, the Nomonox purifier automatically continues to provide quality breathing air.
When refrigeration-based purifiers experience failure, moisture is not removed and the moisture-sensitive catalytic converter is immediately poisoned, destroying its ability to remove carbon monoxide. In addition to low initial cost and maximum protection, Nomonox offers other key benefits:
In addition, to their standard teatures Nomonox Systems can be customized by including:
