3M Adflo Operating Instructions

Description:
The 3M Adflo Powered Air Respirator is a respiratory protection
device, for increased comfort and safety during welding and allied
processes when used as a system in combination with approved
headtops.
3M Adflo Powered Air Respirator is equipped with a particle filter,
spark arrestor, pre filter and a particle filter indicator that displays the
level of particle filter clogging. A range of gas filters (optional) give
additional protection against certain gaseous contaminations.
3M Adflo Odour Filter (optional) reduces unpleasant odour.
3M Adflo Powered Air Respirator incorporates an automatic airflow
control that ensures a constant supply of air during use. An electronic
control unit provides an audible and visible warning of low battery
and/or low air flow into the headtop.
3M Adflo Powered Air Respirator offers a standard and a heavy-duty
(optional) battery.
The airflow creates positive pressure which together with the sealing
to the face prevents particles and other contaminants from entering
the head top.
The Adflo unit has a three bar battery indicator. When all bars are
illuminated the battery has full capacity.
In addition the Adflo unit also has a five step particle filter indicator.
Applications:
The Adflo Powered Air Respirator is designed to provide a supply of
filtered air from the Adflo unit, via a breathing tube, to a head top. The
equipment can be used in environments which have a required
minimum protection factor of 50. The choice of breathing equipment is
governed by the concentration and type of contamination found in the
ambient air.
The complete system protects against particulate contamination and if
the gas filter is used, against certain gaseous contamination.
Standards:
The complete system is a breathing protection device complying with
Australian and New Zealand Standard AS/NZS 1716 Respiratory
protective devices.
Operating instructions:
Switch on 3M Adflo Powered Air Respirator by pressing the ON button
once (nominal airflow), twice (airflow plus). Pressing the ON button a
third time will make 3M Adflo Powered Air Respirator return to nominal
airflow.
One green indicator = nominal airflow (see technical specification)
Two green indicators = airflow plus (see technical specification)
To switch 3M Adflo Powered Air Respirator off, press the OFF button
for at least 1 second. If the red light illuminates together with an
audible warning, this indicates that the airflow is too low (less than
manufacturer's minimum design flow rate). If the low flow alarm is
active for more than two minutes, 3M Adflo Powered Air Respirator
will automatically turn off. 3M Adflo Powered Air Respirator has a
three bar battery indicator showing remaining capacity. When the last
bar starts flashing and an audible warning is heard, less than 5%
battery capacity is remaining. The warning sound will change
noticeable after a while and 3M Adflo Powered Air Respirator will turn
off automatically. See below table for details.
