DESCRIPTION
DESCRIPTION
The OptimAir 6HC Powered Air-Purifying Respirator
(PAPR) is certified by the National Institute for
Occupational Safety and Health (NIOSH) as an air-purify-
ing device designed for use in atmospheres which are
NOT immediately dangerous to life or health (IDLH).
One model is available:
• OptimAir 6HC PAPR with combination cartridges
The OptimAir 6HC combination cartridge may be used
with the Saranex Hood, or the Advantage 3000 (Model
3100).
COMBINATION CARTRIDGES
A combination cartridge consists of particulate filter media
and chemical sorbent in one cartridge package. This type
of cartridge must be used when harmful particulate matter
as well as harmful gases and/or vapors are present.
Do not use combination cartridges with a PAPR hood.
Combination cartridges are approved for use with the
Ultravue
® or Ultra Elite ® full facepieces or Comfo-style
half-facepieces only. Failure to follow this warning can
result in serious personal injury or death.
To select a combination cartridge, you must know the spe-
cific particulate contaminants and their exposure limits, as
well as the gas and/or vapor contaminants and their expo-
sure limits and concentrations. Selection then matches a
specific media which traps known particulates and a spe-
cific sorbent which removes known gas or vapor contami-
nants, resulting in purified air reaching the user.
The motor-blower, battery pack and filters are worn as an
assembly on the support belt. The breathing tube con-
nects the belt-mounted assembly to the facepiece or
hood.
The respirator may be used at temperatures between 0°
and 120°F, and may be worn under flame-retardant gar-
ments.
PRINCIPLE OF OPERATION
The motor-blower draws surrounding air through particu-
late filters and/or chemical cartridges which capture the
contaminants. Purified air passes through the breathing
tube to the facepiece or hood. Air pressure in the face-
piece or hood is higher than the surrounding air. This
means that if a small leak occurs, air will flow from inside
the facepiece or hood to the outside air. This is referred to
as positive pressure. Air flow also provides wearer comfort.
The OptimAir 6HC PAPR is powered by a Lithium battery
pack. The Lithium battery is
NOT rechargeable; however,
the Lithium battery has a very long shelf life (up to 10
years).
Do not recharge a Lithium battery. The Lithium battery
can explode. Failure to follow this precaution can
result in serious personal injury or death.
