Versaflo Showdown: Which 3M PAPR Turbo Unit is Your Workplace Champion?
Posted on 23rd May 2025

TR-315, TR-619, TR-819 – Decoding the Differences in Versaflo Turbo PAPRs
In today’s demanding industrial environments, ensuring robust respiratory protection is paramount. Powered Air Purifying Respirators (PAPRs) offer a superior level of defence and comfort compared to disposable or reusable half-masks, especially for extended wear. As a leading UK-based supplier, The Face Mask Store is committed to helping you navigate the options. This blog delves into three prominent 3M™ Versaflo™ Turbo Units: the TR-315UK, TR-619UK, and TR-819UK. We’ll explore their differences, ideal use cases, and how they align with crucial UK safety standards, ensuring you make an informed choice for your workplace.
Key Takeaways: Versaflo Units at a Glance
- TR-315UK: Your go-to for lightweight, reliable particulate protection in general industrial and healthcare settings.
- TR-619UK: Offers enhanced defence against specific gases and vapours alongside particulates, ideal for more complex chemical environments.
- TR-819UK: The essential choice for intrinsically safe operation in potentially explosive atmospheres (ATEX certified), prioritising safety in high-risk zones.
Understanding PAPRs and UK Safety Standards
Powered Air Purifying Respirators (PAPRs) actively draw ambient air through a filter and deliver a controlled stream of purified air to the wearer’s headtop (hood, helmet, or visor). This positive pressure system offers several advantages:
- Enhanced Protection: Reduces the risk of inward leakage compared to negative-pressure respirators.
- Increased Comfort: The flow of air can make breathing easier and keep the wearer cooler, especially during long shifts.
- Facial Hair Compatibility: Unlike tight-fitting masks, many PAPR headtops do not require a full face seal, making them suitable for individuals with beards or other facial hair.
In the UK, PAPRs must comply with stringent safety regulations. Key standards and bodies include:
- EN 12941: This European Standard specifies requirements, testing, and marking for PAPRs incorporating a helmet or a hood. Compliance ensures the device meets performance criteria for protection.
- Health and Safety Executive (HSE): The HSE provides guidance on selecting and using Respiratory Protective Equipment (RPE). They emphasize risk assessment to determine the appropriate level of protection.
- Assigned Protection Factor (APF): The APF indicates the level of respiratory protection a correctly functioning and fitted RPE is expected to provide. For example, a PAPR with a TH3 classification (when used with an appropriate headtop) can achieve an APF of 40, meaning it can reduce exposure to hazardous substances by up to 40 times the Workplace Exposure Limit (WEL).
- ATEX Directives: For equipment used in potentially explosive atmospheres, ATEX certification (e.g., for Zone 0) is mandatory to prevent ignition sources.
- CE Marking: Indicates that the product meets EU/UK safety, health, and environmental protection requirements.

3M™ Versaflo™ TR-619UK Powered Air Turbo Starter Kit
Advanced Protection Against Particulates, Gases, and Vapours
The TR-619UK (which includes the TR-602E turbo unit) steps up the protection by offering capability against certain gases and vapours in addition to particulates. It’s built for more demanding industrial applications where a broader spectrum of airborne contaminants is present.
- Protection Level: Designed for particulates, gases, and vapours. The starter kit often includes an A2P filter (TR-6310E), effective against organic vapours (with a boiling point above 65°C) and particulates. Other filter types are available for different chemical hazards.
- Airflow Rates: Provides three user-selectable airflow rates for comfort and to adapt to workload.
- Battery: Comes with a high-capacity Lithium-Ion battery for extended operational hours.
- Certifications: CE marked and compliant with EN 12941. The TR-602E unit has an IP54 rating for use in decontamination showers and IP67 for temporary submersion (with cleaning plugs).
- Key Features: Robust design. The TR-619UK kit typically includes the TR-602UK Powered Air Turbo, A2P filter, filter cover, prefilters, spark arrestors, an easy-clean belt, high-capacity battery, charger, and breathing tube. Visual, audible, and vibratory alarms.
- Ideal Use Cases: Chemical processing, paint spraying (e.g., automotive refinishing), heavy industry, pharmaceuticals, and agriculture where exposure to organic vapours and particulates is a concern.
- Not Suited For: Environments requiring intrinsically safe equipment (explosive atmospheres).
3M™ Versaflo™ TR-819E Intrinsically Safe Powered Air Turbo Starter Kit
The Ultimate in Safety for Explosive Atmospheres
The TR-819E (which includes the TR-802E turbo unit) is specifically engineered for use in potentially explosive atmospheres. Its “intrinsically safe” (IS) design ensures it won’t become an ignition source.
- Protection Level: Provides particulate and, with appropriate filters, gas/vapour protection, all within an intrinsically safe design.
- Airflow Rates: Typically offers two selectable airflow rates (e.g., 185 or 205 l/min), optimised for intrinsically safe environments.
- Battery: Uses an intrinsically safe Lithium-Ion battery, designed to prevent sparks.
- Certifications: Critically, it is ATEX certified and IECEx approved for use in Zone 0 environments (where explosive gas atmospheres are continuously present or present for long periods). Also CE marked and compliant with EN 12941. The TR-802E turbo unit has an IP54 rating and can be rated IP67 with cleaning plugs.
- Key Features: Intrinsically safe motor, battery, and circuitry. Tamper-proof casing for the battery. The starter kit typically includes the TR-802E Intrinsically Safe Powered Air Turbo, IS battery, battery attachment tool, airflow indicator, easy-clean belt, charger, P filter, filter cover, prefilters, and spark arrestors.
- Ideal Use Cases: Oil and gas industry, petrochemical plants, mining, pharmaceutical manufacturing in hazardous zones, chemical plants, confined spaces with explosive atmosphere risks, and any environment classified as Zone 0, 1, or 2 (gas) or Zone 20, 21, or 22 (dust).
- Considerations: Its specialised nature means it’s typically chosen only when intrinsic safety is a mandatory requirement due to the higher cost and specific design.

Making the Right Choice for Your Workplace
Selecting the correct Versaflo™ turbo unit is a critical decision that hinges on a thorough risk assessment of your specific workplace hazards, as mandated by the HSE.
- Choose the TR-315UK+ if your primary need is reliable protection against particulates in environments where intrinsic safety is not required. Its lightweight design and simplicity make it excellent for general industrial use and healthcare.
- Opt for the TR-619UK when your workers face a combination of particulates and specific gases or vapours (like those encountered in painting or chemical mixing), and the environment is not potentially explosive. Its robust build and filter options offer greater versatility for mixed hazards.
- Select the TR-819E when intrinsic safety is non-negotiable. If your operations involve potentially explosive atmospheres (Zone 0, 1, 2 or Zone 20, 21, 22), this ATEX-certified unit is essential for compliance and worker safety.
Always ensure that the chosen unit is used with the correct filters for the specific contaminants present and that wearers are properly trained in its use, maintenance, and limitations. Regular filter replacement, battery checks, and adherence to UK guidance on fit testing (where applicable for certain headtops, though loose-fitting PAPRs often don’t require it) are crucial for maintaining protection.
