Using the 3M™ Combination Dual Airline Breathing Tu bes without Cartridges and Filters
To use the 3M combination dual airline breathing tubes (SA-1600 and SA-2600) without cartridges or filters, attach a 3M™ 6880 Bayonet Cap to each outer bayonet mount on the dual airline breathing tube. When used as a straight, Type C, continuous flow supplied air respirator, the Assigned Protection Factor is 1000 times the PEL or TLV guidelines for full facepiece respirators.

3M™ Responder Cartridge and Canister Assembly
The 3M CP3N canister and FR-64 cartridge are NIOSH approved only with the 6894 nose cup assembly in place. Failure to do so may result in sickness or death.
Overtightening may cause damage to the DIN Port Adapter housing and/or gasket and allow unfiltered air to enter the facepiece, which may result in sickness or death.
Important information on proper use and use limitations is provided in the User Instructions with the CP3N Canister and FR-64 Cartridge. The two bayonet ports on the lens must be closed using 6880 Bayonet Caps and 6895 Inhalation Port Gaskets. Before installing the canister, check that the 6876 Breathing Tube Gasket is in place and in good condition. Screw the responder canister/cartridge into the DIN Port Adapter and tighten with moderate hand pressure (Fig. 6).
