The SR 700 Fan Unit is a belt-mounted blower/filtration
unit. To form a complete powered air purifying (PAPR)
respirator system, the SR 700 must be combined with
the appropriate filters, battery pack and respirator
facepiece.
The SR 700 PAPR system is intended to provide
respiratory protection against certain particulates. The
SR 700 is NIOSH Tight Fit approved with certain
components. Refer to NIOSH Approval Label for list of
approved components.
The SR 700 PAPR can be used as an alternative to
air-purifying filter respirator in all situations for which
these are recommended. This applies particularly to
work that is hard, warm or of long-duration. This
respirator can be used for protection against a mixture
of contaminants that are present simultaneously or
alternately against one contaminant then another (using
the same filters) if the mixture meets the following
conditions:
• The filter must be approved for all contaminants
present.
• Particulates (dusts, mists, fumes, asbestos,
radionuclides) can be mixed with any other
particulate.
• Contaminants present simultaneously must be
below IDLH levels for the specific contaminants. If
any one contaminant in the mixture exceeds the
IDLH concentration then the entire mixture must be
treated as IDLH and the respirator cannot be used
(except for escape from particulates with appropria-
te filter).
RESPIRATOR USE LIMITATIONS
The SR 700 system must not be worn:
• In Oxygen deficient atmospheres
• Where contaminant concentration is unknown
• Where contaminant concentration is at or above
immediately dangerous to life or health (IDLH)
• Where maximum use concentrations are exceeded
• Full facepiece: where the contaminant concentration
is 1000 times the exposure limit.
• Where the limitations outlined in the applicable
NIOSH approval are exceeded.
• Where any applicable limitation contained in a
standard established by a regulatory agency (such
as OSHA) with jurisdiction over the wearer is
exceeded.
A listing of acceptable exposure limits is available from
the American Conference of Governmental Industrial
Hygienists (ACGIH); Occupational Safety and Health
Administration (OSHA); National Institute for Occupatio-
nal Safety and Health (NIOSH) and American Industrial
Hygiene Association (AIHA).
The SR 700 requires the use of one lithium ion (Li-ion)
type battery heavy duty HD; one full face mask and two
(2) filters. The SR 700 can be operated for up to 8
hours.
The same control button is used for starting, stopping
and selection of operating status. The SR 700 Fan Unit
has a display with the following symbols:
• Small fan symbol that lights up with a green light
during normal operation 6.2 CFM (175 l/min).
• Bigger fan symbol that lights up with a green light
during boosted operation 7.9 CFM (225 l/min).
• Triangle that lights up with a red light if the air flow
should cease or if the filters are clogged.
• Battery symbol lights up to indicate the battery
capacity at start and when the battery capacity is
low.
To operate the fan unit:
• Start the fan by pressing the control button. Fig. 13.
• After the button has been pressed, a programmed
test will be run on the fan unit, during which the
symbols on the display will light up and the sound
signal will sound. Fig. 14.
• Battery symbol lights up and indicates the battery
capacity.
o Lights green: > 70 %
o Flashing green: 50-70 %
o Lights yellow: 20-50 %
o Flashing red: < 20 %
• After the internal test, all symbols will be extinguis-
hed except the small green fan symbol. This
indicates normal operating status with a flow of at
least 6.2 CFM (175 l/min).
• If the button is pressed again, boosted operating
status will be activated, with a flow at least 7.9 CFM
(225 l/ min). This is indicated by the larger green fan
symbol lighting up.
• To revert to normal operation, press the control
button once again.
• To switch off the fan unit, keep the control button
depressed for about two seconds.
Air flow rates
On normal operation, the fan delivers at least 6.2 CFM
(175 l/ min), and on boosted operation, at least 7.9 CFM
(225 l/min). The automatic flow control system of the fan
unit maintains these flows constant throughout the
operating time. The SR 700 is equipped with automatic
air flow control, with compensation for air pressure and
temperature, and initiates an alarm by sound/light
signals in the event of an obstruction in the air flow.
SR 700 Warning System/Alarm Signals
If the air flow should drop below the preselected value
6.2 CFM or 7.9 CFM (175 or 225 l/min), the SR 700 Fan
Unit will provide the following alarms:
• A pulsating sound signal will be heard.
• The red warning triangle of the display will flash.
WARNING - Immediately interrupt the work, leave
the area, and inspect the equipment. Do not
remove the SR 700 respiratory inlet covering while
you are in contaminated atmosphere.
If the PARTICULATE filters are clogged, this is indicated
in the following way:
