3M Versaflo TR-332 High Capacity Rechargeable Battery for TR-300N PAPR Unit Overview
The 3M Versaflo TR-332 High Capacity Rechargeable Battery is a spare or replacement power pack for the 3M Versaflo TR-300N powered air-purifying respirator (PAPR) turbo unit. It is an accessory, not a standalone respirator: by itself the TR-332 delivers no respiratory protection, carries no assigned protection factor, and ships without a headcover, breathing tube, filters, or cartridges.
Its job is to power the TR-300N blower so the unit can pull air through its filters and push a steady stream of filtered air to a Versaflo headtop. The high-capacity rating means it is built to run longer on a charge than a standard-capacity TR-300N battery, which is useful for full-shift work and back-to-back tasks where stopping to swap or recharge mid-job is disruptive. Many crews keep a charged spare on the shelf so a unit is never down waiting on a charger.
Compatibility is the key buying decision. The TR-332 is matched to the TR-300N-series turbo — confirm your unit is a TR-300N (the battery clips into that turbo and charges on its matched charger) before ordering. It is not a substitute for the turbo, charger, or filters, and it does not change your PAPR's airflow rating or the protection factor of the headtop you pair with it.
A complete PAPR is a loose-fitting or tight-fitting system depending on the headtop chosen; loose-fitting hoods and helmets do not require a facial seal or fit test, while any tight-fitting facepiece does. Whatever headtop you run, the assembled system must be set up, airflow-checked, and used per 3M's user instructions, NIOSH 42 CFR 84 approval, and OSHA 1910.134. The TR-332 is one component inside that approved system. Browse the full range of powered air-purifying respirators and broader respiratory protection, and see the respiratory protection guide if you are still selecting a system.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Replacing a worn or aging TR-300N battery | Ideal | Direct replacement power pack for a TR-300N turbo whose original battery no longer holds a full charge. |
| Keeping a charged spare for full-shift or back-to-back use | Ideal | High-capacity rating extends runtime; a second battery keeps the unit running while one charges. |
| Extending runtime on a TR-300N PAPR system | Strong | Built to run longer per charge than a standard-capacity TR-300N battery for longer tasks. |
| Powering a TR-600 or TR-800 series Versaflo unit | Not compatible | The TR-332 is matched to the TR-300N turbo only; TR-600/TR-800 use their own battery packs. |
| Buying a first-time complete respirator | Not suitable alone | This is a battery accessory, not a respirator. Start with a complete TR-300N PAPR kit, then add the TR-332 as a spare. |
| Adding respiratory protection without an existing PAPR | Not applicable | Provides no protection on its own. Select a full PAPR or cartridge respirator from the respiratory protection range first. |
Respirators must be selected, fit, and maintained under a written program per OSHA 29 CFR 1910.134. Tight-fitting facepieces require a clean-shaven seal, an annual fit test, and a user seal check every time they are donned; loose-fitting PAPR hoods and helmets do not seal to the face but still require the program and the correct assigned protection factor. Use only NIOSH-approved cartridges/filters matched to the specific hazard, never use any air-purifying respirator in an IDLH or oxygen-deficient atmosphere, and follow the change-out schedule. See the respiratory protection guide and how to do a user seal check.
Pros & Cons
Pros
- High-capacity design extends runtime versus a standard-capacity TR-300N battery
- Genuine 3M Versaflo accessory matched to the TR-300N turbo
- Lets you keep a charged spare so a PAPR is never down waiting on a charger
- Rechargeable, so no consumable single-use power cost
- Simple drop-in replacement for an aging or failing TR-300N battery
Cons
- Not a respirator and provides zero protection on its own
- Compatible with the TR-300N series only, not TR-600 or TR-800 units
- Ships as a battery only, no charger, turbo, filters, or headtop
- Requires a matched 3M charger to recharge (sold separately)
How It Compares
The TR-332 is a power component within the 3M Versaflo PAPR line, so the useful comparison is across battery and turbo families rather than against respirators. Confirm your turbo series before buying — batteries are not cross-compatible between the TR-300N, TR-600, and TR-800 platforms.
| Item | What it is | Fits | Notes |
|---|---|---|---|
| TR-332 (this item) | High-capacity rechargeable battery | TR-300N series | Longer runtime than the standard TR-300N battery; battery only |
| Standard TR-300N battery | Standard-capacity rechargeable battery | TR-300N series | Shorter runtime; the baseline pack the TR-332 upgrades |
| TR-300N turbo unit | Blower/turbo (the PAPR core) | TR-300N system | The unit the TR-332 powers; not interchangeable with the battery |
| TR-600 / TR-800 batteries | Battery packs for other Versaflo platforms | TR-600 / TR-800 only | Not compatible with the TR-300N or the TR-332 |
If you still need the headtop or hood for your system, see the 3M Versaflo S-433L-5 PAPR hood (large), and browse all powered air-purifying respirators.

Frequently Asked Questions
Is the 3M Versaflo TR-332 a respirator?
No. The TR-332 is a high-capacity rechargeable battery accessory for the TR-300N PAPR turbo. It provides no respiratory protection on its own and must be used as part of a complete, NIOSH-approved Versaflo PAPR system.
Which 3M PAPR units does the TR-332 fit?
It is matched to the 3M Versaflo TR-300N-series turbo unit. Confirm your unit is a TR-300N before ordering; it is not compatible with TR-600 or TR-800 batteries or units.
Does the TR-332 come with a charger?
No. The TR-332 ships as a battery only. It recharges on a matched 3M Versaflo charger, which is sold separately.
What does 'high capacity' mean for the TR-332?
High capacity means it is built to run longer on a single charge than a standard-capacity TR-300N battery, which helps with full-shift work and back-to-back tasks between charges.
Does the TR-332 include filters, a hood, or a breathing tube?
No. It is a battery only. Filters, the breathing tube, and the headtop or hood are separate components of the PAPR system and must be purchased separately.
Does the TR-332 have an assigned protection factor (APF)?
No. A battery has no APF. The protection factor comes from the assembled PAPR and the headtop you choose, used per the NIOSH approval and OSHA 1910.134.
Can I use the TR-332 to upgrade runtime on my existing TR-300N?
Yes, if your unit is a TR-300N. The high-capacity TR-332 is designed to extend runtime compared with the standard battery, and many users keep a charged spare to avoid downtime.
Will the TR-332 work in a TR-600 or TR-800 Versaflo PAPR?
No. The TR-332 is matched to the TR-300N platform only. TR-600 and TR-800 units use their own dedicated battery packs.
Do I need a fit test to use a PAPR powered by the TR-332?
It depends on the headtop, not the battery. Loose-fitting Versaflo hoods and helmets do not require a fit test or facial seal, while any tight-fitting facepiece does. See our user seal check guide for tight-fitting headtops.
Is the TR-332 a genuine 3M part?
Yes. It is a genuine 3M Versaflo accessory designed for the TR-300N system, so it matches the turbo's charging and mounting interface.
How many batteries should I buy for one TR-300N unit?
Many crews keep at least one spare in addition to the in-use battery, so the PAPR keeps running on the spare while the other charges. The high-capacity TR-332 is a good choice for that rotation.
Can I use this PAPR system in IDLH or oxygen-deficient atmospheres?
No. PAPRs are air-purifying respirators and must never be used in IDLH or oxygen-deficient atmospheres beyond their rating. Use a supplied-air or SCBA system for those conditions, per OSHA 1910.134.
