3M Versaflo TR-813N High Durability PAPR Assembly Kit Without Facepiece

3M Versaflo TR-813N High Durability PAPR Assembly Kit Without Facepiece

The 3M Versaflo TR-813N PAPR assembly is engineered for demanding industrial environments where intrinsic safety is a non-negotiable regulatory requirement. Approved to UL 60079 (6th edition, 2013), this powered air-purifying respirator system is approved for use in Class I/II/III, Division 1, Groups C, D, E, F, and G environments at temperature rating T4 - making it one of the few NIOSH-approved PAPR systems approved for use in potentially explosive atmospheres.

Unlike standard PAPR systems, the TR-813N features the intrinsically safe TR-802N blower motor, engineered to never generate a spark - even under fault conditions. This is a critical safety requirement in mines, refineries, chemical plants, and any classified hazardous location where ignition sources can have catastrophic consequences.

The assembly ships without a facepiece, providing maximum flexibility to pair with your team's existing approved facepiece or the one best suited to your specific application. Full compatibility with Versaflo hoods, helmets, and faceshields allows complete system customization without replacing the power unit.

3M manufacturer code: 7100150924, model: TR-813N

The included TR-626 high durability belt is specifically reinforced for severe working conditions - abrasion, moisture, and repeated loading. It provides firm motor support while distributing weight ergonomically across the hips, reducing fatigue during extended shifts in demanding environments.

The system also includes the TR-830N standard battery, TR-838 battery attachment tool, TR-971 airflow indicator to verify airflow in real time, and BT-30 adjustable breathing tube. Everything needed to put the system into immediate service - except the facepiece and filter, which are selected based on your specific application requirements.

NIOSH-approved, the TR-813N delivers consistent airflow for effective protection against particulate hazards, with the ability to add HEPA filters (TR-6710N, sold separately) for high-efficiency filtration. Battery life on the TR-830N ranges from 4 to 8 hours depending on selected airflow setting and conditions.

Key Benefits of the Versaflo TR-813N Assembly

UL 60079 Intrinsically Safe Approval

The TR-802N motor is approved for Class I, II, and III, Division 1 explosive atmospheres. This approval exceeds standard NIOSH requirements and positions the TR-813N as the reference solution for explosion-risk zones in mining, chemical, and petroleum industries. It meets requirements for environments with flammable gases, combustible dusts, and ignitable fibers.

TR-626 High Durability Belt - Extended Comfort

Constructed from abrasion-resistant polyurethane, the TR-626 belt withstands harsh, wet, and abrasive environments. Its ergonomic design distributes the motor's weight across the hips, enabling full work shifts without excessive discomfort. Significantly more robust than the standard belt, ideal for workers exposed to significant physical demands throughout their shift.

Controlled Airflow with Included TR-971 Airflow Indicator

The TR-971 airflow indicator allows instant verification that airflow meets NIOSH requirements before each use. This is an essential verification tool for respiratory protection programs requiring airflow documentation, particularly in environments regulated by OSHA or provincial health and safety authorities in Canada.

Flexibility - Compatible with Versaflo Facepieces

Without an imposed facepiece, the TR-813N integrates with Versaflo S, M, and L series hoods, Versaflo M-series helmets, and available faceshields. This modularity allows you to select the protection level and comfort appropriate for each application without replacing the entire system, protecting your capital investment in power units.

Simplified Maintenance - Field-Accessible Upkeep

The TR-802N motor is designed for easy cleaning with a damp cloth. The TR-830N battery is removable and rechargeable, and the BT-30 tube is flexible and adjustable. The assembly can be maintained without specialized tooling, reducing downtime and maintenance costs - critical for high-utilization environments where equipment availability directly impacts productivity and safety compliance.

Frequently Asked Questions - TR-813N Assembly

Q: What is the difference between the TR-813N and the TR-800HIK?

A: The TR-813N uses the intrinsically safe TR-802N motor (UL 60079 approved for explosive atmospheres) and the high durability TR-626 belt. The TR-800HIK includes a facepiece and uses a standard motor. The TR-813N is without a facepiece, offering greater flexibility for teams that already have approved facepieces or require a specific facepiece for their application.

Q: Which filters are compatible with the TR-813N?

A: The TR-813N is compatible with the TR-6710N HEPA filter (magenta/grey, protection against solid and liquid particles) and other filters in the Versaflo TR-800 series. Filter selection depends on the contaminants present - an industrial hygienist should confirm filter selection in complex environments with multiple hazards.

Q: Is the TR-813N suitable for use in coal mines or refineries?

A: Yes. The UL 60079 approval, Class I/II/III, Division 1, Groups C/D/E/F/G, T4 specifically covers atmospheres containing flammable gases, combustible dusts, and ignitable fibers. This is among the most demanding approvals for powered air respirators, recognized by both Canadian and American regulations for classified hazardous locations.
