ArcOne Clean Air Flow - Manual (Page 6)

This Clean Air Flow TM system is used in a welding environment where
protection is required against harmful particles and mist. The Clean
Air Flow
TM , in conjunction with ArcOne’s Auto Darkening Lens and Vi-
per and Vision welding helmets eliminate much of the wasted motion and
discomfort associated with welding. You will receive a constant fl ow of fresh air,
which will allow you to comfortably remain safely in your work environment for a
longer period of time, and is of particular benefi t where working conditions are
hot or humid.
The Clean Air Flow TM blower unit supplies an over capacity of 170 Liters per min-
ute of fi ltered air to the headtop, and allows the user to breathe without having to
overcome the resistance of the fi lter. Considering that an adult person requires
an average of 45 liters of air per minute, the over capacity ensures a slight over-
pressure and thus a high degree of protection.
The Clean Air Flow
TM system is powered by a rechargeable Lithium-Ion battery,
which is encased in durable lightweight plastic. The battery securely attaches to
the blower unit. The battery provides protection for an 8 hour shift. The battery
is delivered in the uncharged state; the charging time for a fully discharged battery
is 8 hours. (See Section 2.1 Battery Charging)
The Clean Air Flow
TM blower unit should be fi tted with a fi lter appropriate to the
application and selected by a competent person with a full knowledge of respiratory
hazards, and their concentrations that are applicable in the workplace. To ensure
adequate protection, it is essential that the blower unit is correctly confi gured and
that the correct fi lter is used. (See Section 2.2 Filters)
If there is any doubt of final determination of respirator
applicability and fi lter selection, it must be made by an on-site safety
specialist or industrial hygienist. (or contact the National Institute
of Occupational Safety and Health).
