The 3M TR-814N Versaflo Easy Clean Assembly is an intrinsically safe Powered Air Purifying Respirator (PAPR) belt-mounted system for hazardous locations. The assembly includes the intrinsically safe TR-802N motor/blower, the intrinsically safe TR-830 lithium-ion battery, a BT-30 length-adjusting breathing tube, a TR-627 Easy Clean belt, and a TR-971 airflow indicator. Important: it is an assembly, not a complete respirator — it does not include a headtop/headgear or any filters or cartridges. You add a compatible 3M Versaflo TR-800 Series headtop plus the filters or cartridges for your hazard to build a complete PAPR. It ships with free shipping from Industrial Safety Products.

Yes. The 3M TR-814N is intrinsically safe (IS). The TR-800 motor/blower with the TR-830 battery has been tested and classified by Underwriters Laboratories (UL) for use in Hazardous Locations, rated Division 1 for Class I, II, and III; Groups C, D, E, F, and G; Temperature Code T4 — under the most current standard, UL 60079, 6th Edition (2013). It also carries Ex ia ratings (Ex ia I Ma; Class I Zone 0 AEx ia IIB T4; Zone 20 AEx ia IIIC T135) and is rated for ambient temperatures from −20 °C to 55 °C. This makes it suitable for environments with flammable gases or combustible dusts, such as oil and gas or pharmaceutical processing.

Intrinsically safe (IS) means the equipment is designed and certified so it cannot release enough electrical or thermal energy to ignite a flammable gas, vapor, or combustible dust — even under fault conditions. For the 3M TR-814N, UL tested and classified the TR-800 blower with the TR-830 battery to the "Ex ia" protection level, the highest IS category, for Hazardous Locations (Division 1, Class I/II/III, Groups C–G, T4). Bright yellow detailing visually distinguishes the intrinsically safe TR-800 from non-IS 3M models so workers can identify the correct unit for a classified area.

Yes. The 3M TR-814N is part of a NIOSH-approved PAPR system. To achieve a complete NIOSH-approved respirator, the TR-800 blower assembly must be paired with a compatible 3M Versaflo headtop and the correct 3M filters or cartridges, per the assembly's NIOSH approval label. Used together as specified, it provides NIOSH-approved powered air-purifying respiratory protection.

The 3M TR-814N uses a standard-capacity, rechargeable lithium-ion battery (TR-830) rated for approximately 4 to 8 hours of runtime, depending on the headtop, filter/cartridge, and airflow setting selected. The intrinsically safe battery includes a bumper to help absorb impact and attaches mechanically to help prevent accidental removal during use. Visual and audible alarms warn the user of low battery and low airflow.

You need to buy them separately. The TR-814N is an Easy Clean assembly — it provides the blower, battery, breathing tube, belt, and airflow indicator, but does not include a headgear/headtop or any filters or cartridges. To complete the respirator, add a compatible 3M Versaflo TR-800 Series headtop plus the particulate filters or gas-and-vapor combination cartridges appropriate for your application. This modular approach lets you configure one PAPR for many hazards.

With the correct 3M cartridges or filters installed, the TR-814N provides protection against particulates and against certain gases and vapors — you select particulate-only filters or gas-and-vapor combination cartridges to match the hazard. Because it is intrinsically safe, it's designed for tasks and industries where flammable gases or combustible dusts may be present, including painting, spraying, welding, paint preparation, and composite finishing, and sectors such as oil and gas and pharmaceutical manufacturing. Multiple airflow rates let the worker balance comfort and protection.

Yes, in many cases. The TR-814N is used with loose-fitting Versaflo headgear, which does not rely on a tight face seal. That allows it to accommodate workers with limited facial hair and those who wear prescription eyewear — a key advantage over tight-fitting respirators that require a clean-shaven seal and pass a fit test. Always confirm the specific headtop's fit and your site's respiratory program requirements.

If you work in classified hazardous locations, yes — that's exactly what sets it apart. A standard PAPR cannot legally or safely be used where flammable gases or combustible dusts are present, because its electronics could be an ignition source. The TR-814N's TR-800 blower and TR-830 battery are UL-classified intrinsically safe (Division 1, Class I/II/III, Groups C–G, T4), so it delivers powered respiratory protection in atmospheres where a conventional PAPR is prohibited. For non-classified environments a standard PAPR may suffice; for oil and gas, chemical, or pharmaceutical areas with ignition risk, the intrinsic safety is the deciding feature.

The "Easy Clean" configuration pairs the TR-800 PAPR with the TR-627 Easy Clean belt (and supports optional disposable breathing-tube covers), making the unit faster to wipe down, decontaminate, and store between shifts — useful in pharmaceutical and other clean-critical operations. Color-coded, intuitive touch points make it simple to operate. The 3M TR-814N Versaflo Easy Clean Assembly is available at Industrial Safety Products (industrialsafetyproducts.com) with free shipping.
