3M™ Dual Airline System
3M™ Dual Airline Respirator Assembly
User must follow Dual Airline Supplied Air Respirators User Instructions provided with the 3M™ Dual Airline Supplied Air Respirators.
Assembly of 3M™ Combination Dual Airline Respirator with Cartridges and/or Filters
The 3M™ Front-Mounted SA-1600 and Back-Mounted SA-2600 versions of the Dual Airline Breathing Tubes allow use of selected NIOSH approved
3M™ 6000 Series Cartridges 6000 Series and Filters 2000 Series. For the listing of approved cartridges and filters, reference the NIOSH Approval
Label included with dual airline adapter kits.
To assemble 3M™ Dual Airline Combination Breathing Tubes with 3M™ Cartridges/Filters, the facepiece inhalation valves must be removed.
IMPORTANT: If the facepiece is to be used in air-purifying mode (without using the 3M SA-1600 or SA-2600 breathing tubes), 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™ Combination Dual Airline Breathing Tubes SA-1600 and SA-2600 without cartridges or filters, attach a 3M™ Bayonet Cap 6880
to each outer bayonet mount on the dual airline breathing tube. When used as a Type C, continuous flow supplied air full facepiece respirator, the
Assigned Protection Factor is 1000 times the PEL or other occupational exposure limit.
To meet the U.S. National Institute for Occupational Safety and Health (NIOSH) requirement for minimum (4cfm/115 lpm) and maximum
(15cfm/424 lpm) airflow, the air control valves approved for use with the 3M™ Respirators 7000 Series must be operated within the supply
pressure ranges and hose lengths stated in User Instructions with air regulating valves. 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.

FITTING INSTRUCTIONS

Must be followed each time respirator is worn.
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.
Standard eyeglasses cannot be worn with full facepiece respirators. If corrective eyeglasses are required a 3M™ Spectacle Kit must be used inside
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.
NOTE: Before assigning any respirator to be worn in a contaminated area, a qualitative or quantitative fit test must be performed per OSHA 29
CFR 1910.134, or CSA Standard Z94.4.
Donning Respirator
1. Fully loosen all six head straps. With one hand pull hair back out of facepiece sealing area. Place chin in the respirator chin cup. While holding the
facepiece in place, pull the head harness to back of head (Fig. 13).
2. Pull the ends of the six straps to adjust tightness, starting with the neck straps first followed by the temple straps and finally forehead straps. Do
not overtighten the headstraps (Fig. 14).
3. Perform a positive and/or negative pressure user seal check each time the respirator is donned.

USER SEAL CHECKS

Always check the seal of the respirator on your face before entering a contaminated area.
Positive Pressure User Seal Check
1. Place the palm of the hand over the exhalation valve cover and exhale gently (Fig. 15).
2. If the facepiece bulges slightly and no air leaks are detected between the face and facepiece, a proper seal has been obtained.
3. If air leakage is detected, reposition respirator on face and/or readjust tension of straps to eliminate the leakage and recheck seal.
If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.
