3M™ Supplied Air Systems
To meet the U.S. National Institute for Occupational Safety and Health (NIOSH) requirement for minimum (4 CFM/115 lpm) and maximum (15
CFM/424 lpm) air flow, the air control valves approved for use with the 3M™ Half Facepiece Respirators 7500 Series must be operated within the
correct supply pressure ranges and hose lengths. Failure to do so may result in sickness or death.
In Brazil, the Brazilian Association of Technical Standards (ABNT) NBR 14372 requires a minimum of 120 lpm and maximum of 280 lpm air flow for
breathing air for half and full facepiece respirators.
OSHA standard 29 CFR 1910.134 requires that employers provide breathing air which shall "meet at least the requirements of the specification for
Grade D breathing air as described in Compressed Gas Association Commodity specification G-7.1-1997" in the United States. In Canada, breathing
air systems must be supplied air which meets at least the requirements of CSA Standard Z180.1. Failure to do so may result in sickness or death.
In Brazil breathing air systems must be supplied with air, which meets ANSI Z86.1-1989/CGA G-7.1, Grade D breathing air.
Assembly of 3M™ Dual Airline Breathing Tubes
1. Hold the facepiece in front of you so that the 3M logo is facing you. Align the two branches of the breathing tube over the two bayonet mounts
on facepiece. For the 3M™ Breathing Tubes SA-1500 or SA-1600, make sure that 3M logo on breathing tube and on half facepiece are both
facing towards you. For 3M™ Breathing Tubes SA-2500 *(07148) or SA-2600 *(37001), make sure that the 3M logo on breathing tube is facing in
opposite direction to 3M logo on half facepieces (Fig. 6). SA-1500/SA-2500 shown.
2. Twist each branch of breathing tube clockwise a quarter turn until it is firmly seated in the bayonet and cannot be turned further (Fig. 7 and 8).
Do not forcibly overturn as the bayonet could be damaged.
SA-1500/SA-2500 shown.
3. Attach airline to approved air regulators per pressure schedules in dual airline, supplied air respirators
User Instructions.
Assembly of 3M™ Combination Dual Airline Breathing Tubes with Cartridges and/or Filters
The SA-1600 (front-mounted) and SA-2600 *(37001) (back-mounted) versions of the 3M™ Dual Airline Breathing Tubes allow use of selected,
NIOSH-approved 6000 series cartridges and 2000 Series filters. For listing of approved cartridges and filters, reference NIOSH approval label included
with 3M dual airline breathing tubes with cartridges and/or filters.
1. Remove the inhalation valves from the facepiece and store them so they remain flat.
2. Attach SA-1600 or SA-2600 breathing tubes to facepiece per the procedures outlined previously. The procedure is identical to the SA-1500 and
SA-2500 *(07148) models.
3. Make a selection of cartridges and/or filters that meets your respiratory protection requirements, and attach to the outer bayonets of SA-1600 or
SA-2600 breathing tubes (Fig. 9).
4. Don facepiece per procedures outlined in Donning Respirator instructions.
5. After being properly fit tested, perform a positive and negative pressure user seal check each time the respirator is donned per procedures outlined
in User Seal Check instructions.
If you cannot achieve a proper fit, DO NOT enter contaminated area. See your supervisor.
IMPORTANT: If the facepiece is to be used in air-purifying mode (without using the 3M™ Breathing Tubes SA-1600 or SA-2600), the inhalation valves
must be replaced in the facepiece before use.
Using the 3M™ Combination Dual Airline Breathing Tubes without Cartridges and/or Filters
To use the 3M™ Breathing Tubes SA-1600 or SA-2600 *(37001) without cartridges or filters, attach a 3M™ Bayonet Cap 6880 *(37002) to each
outer bayonet mount on the breathing tube. When used as a Type C, continuous flow supplied air half facepiece respirator, the Assigned Protection
Factor is 50 times the PEL or other occupational exposure limit.

FITTING INSTRUCTIONS

Must be followed each time respirator is worn.
The 7500 series half facepiece suspension can be configured as a standard fixed suspension or a drop down suspension for individuals using
hard hats. Position straps beneath locking tabs for standard fixed suspension (Fig. 10) or position straps over locking tabs for optional drop down
suspension (Fig. 11).
NOTE: Do not use with beards or other facial hair or other conditions that prevent a good seal between the face and the faceseal of the respirator. To
help maintain a good seal between the face and the faceseal all hair, hoods, or other equipment must be kept out of respirator faceseal area at all
times.
Donning (Standard Suspension)
1. Adjust head cradle size as needed to fit comfortably on head. Place the respirator over the mouth and nose, then pull the head harness over the
crown of the head. Grasp the bottom straps, place them at the back of the neck and hook them together.
2. Pull the ends of the straps to adjust the tightness. Do not over-tighten (Fig. 13).
3. Perform a positive and/or negative pressure user seal check each time the respirator is donned.
If you cannot achieve a proper fit, DO NOT enter contaminated area. See your supervisor.
Donning (Drop Down Suspension)
1. Adjust head cradle size as needed to fit comfortably on head.
2. While holding head harness strap ends with one hand, slide the facepiece up onto your face (Fig. 12). Next grasp strap ends with each hand and
hook them together at back of neck.
3. Adjust strap tension by pulling strap ends until a secure fit is obtained. Balance strap tension by adjusting at top and bottom strap buckles. Do
not over tighten. (Strap tension may be decreased by pushing out on back side of buckles.)
