Breathing Tubes
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+ PAPR is approved for use with 3M™ Versaflo™
Breathing Tubes. Select an approved breathing tube that is appropriate for the work conditions.
1. Insert the end of the breathing tube with the bayonet fitting (two small prongs) into the parallel slots in the air outlet
of the motor/blower (Fig. 8).
2. Twist the breathing tube 1/4 turn to the right to lock it into place.
3. Refer to the User Instructions for the headgear to be used for procedures to connect the breathing tube to the
head gear.

for contamination of the outlet.

Headgear
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+ is approved for use with many 3M headgear options.
Refer to the headgear User Instructions for information on attaching and donning the headgear to be used, and to
determine assigned protection factor (APF) for the complete respiratory protection system. Consult 3M Technical Data
Bulletin #175 for additional information on APFs and supporting test data.
Belts
Select an approved belt appropriate for the work conditions. Install the belt by threading the end of the belt through the
retaining slots on the back side of the motor/blower (Fig. 10). Position the motor/blower so it rests in the small of the back
or other location around the waist. Tighten belt for a snug fit. For TR-325 (nylon web) and TR-327 (easy clean), multiple
belts can be interconnected to provide the wearer with a comfortable fit. An optional belt extender (15-0099-06) is
available for the TR-326 leather belt. If needed two leather belts could also be interconnected.
For TR-325 & TR-327 belts, three belt sliders are included. The sliders are optional and two could be placed on the belt on
both sides of the motor/blower to prevent the motor/blower from moving along the belt. The third slider could be used as a
keeper for extra belt length if desired. Place the sliders on the belt so the rounded side is on the exterior of the belt.
Suspenders (optional)
The TR-329 suspenders may be used in conjunction with the TR-300+ system belts. Refer to the TR-329 User
Instructions for information on attaching the suspenders to the TR-300+ belts.
