Welding is an essential process required in many industries, but it comes with the risk of exposure to dangerous fumes and particles. These fumes emitted during welding contain a cocktail of toxic gases and particulates that can cause serious respiratory problems over time.
Traditional air-purifying respirators with disposable filters do not provide adequate protection against these welding fumes. However, a new class of respiratory protection devices is emerging as a great option with better protection for welders. These devices are popular as powered respirators, revolutionising respiratory safety.
This blog will give you a brief idea of what powered respirators are, along with their types and benefits. This may also help you decide which one to choose under different concentrations of particulates.
What are Powered Air Respirators?
Powered respirators are also known as PAPRs or powered air-purifying respirators. They are a type of respiratory protection that uses a battery-powered blower to pull contaminated air through special filters. The cleaned air is then sent into a facepiece, helmet, or hood for the welder to breathe.
Unlike passive air-purifying respirators that rely on lung power to draw air through the filter, PAPRs actively push filtered air to the welder. This positive pressure helps prevent leakage of contaminated air into the facepiece, providing higher assigned protection factors than passive respirators.
Advantages of Powered Air Respirators
Powered respirators provide multiple advantages over passive respirators:
- Superior Filtration – High-efficiency particulate filters remove 99.97% of particles. Powered air protectors constitute activated carbon filters, which also absorb harmful welding fumes and gases.
- Cooling Airflow – The constant airflow keeps welders cool and comfortable, even in hot environments. There is no more suffocating behind a mask.
- Increased Visibility – PAPRs are paired with hoods and helmets that protect the eyes and face without compromising visibility. Welding helmets can also integrate auto-darkening filters.
- Versatility – Interchangeable filters and facepieces accommodate protection from particles, gases, or biohazards.
- User Safety – The positive pressure in the protectors reduces contamination risk. It also offers low breathing resistance and prevents overexertion. These protectors even integrate audible and visual alarms that alert users to any malfunctions.
- Communication – PAPRs allow easy voice communication, unlike passive respirators. Some PAPR systems even integrate wireless communication capabilities.
Top 5 Best Respirators Protection
Many manufacturers offer PAPR solutions for welding, metalworking, and hot work. Here are the top 5 best respirators protection available in the UK:
1. Sundstrom SR100
The Sundstrom SR100 PAPR features a nylon hood, adjustable head suspension, and a built-in auto-darkening welding shield for complete head protection with excellent visibility. The Sundstrom SR100 filters particles down to 0.3 microns at 99.997% efficiency.
2. Stealth P3 Dust Respirator
The Stealth P3 Dust Mask provides effective respiratory protection against fine dust, mists, and fumes. It features a lightweight neoprene face seal and adjustable straps to ensure a comfortable fit. This respirator mask utilises a P3 rating filter, which filters out 99.95% of airborne particles.
3. 3M Versaflo M-300 Series
The 3M mask of the Versaflo M-300 series is a feature-rich PAPR for welding that takes modular and scalable protection to the next level. The system includes interchangeable lithium-ion batteries that provide up to 10 hours of runtime.
4. Honeywell North 8002
The Honeywell North 8002 SilentPro PAPR provides a lightweight and compact respiratory solution ideal for welding.
It delivers 160 litres per minute airflow and ATMO-SEAL connection technology for a tight facepiece seal. The lithium-ion battery runs for up to 12 hours.
5. JSP Force8 Half-Mask
The JSP Force8 Half-Mask adjusts to your face for customised comfort. Its adjustable straps and flexible rubber design fit most head shapes and sizes. The mask really packs a punch with its P3 filters that capture dust, fumes, and toxic gases, while the easy-breathe exhalation valve reduces stuffiness.
How to Choose the Right PAPR for Welding
With the expanding range of powered air respirators for welders, selecting the right model for your needs is crucial. Here are some tips on choosing a suitable PAPR system:
- Identify Hazards – Consider the types of welding processes and materials you work with. The fumes and gases produced will determine the type of filters needed.
- Required Protection Level – Match the minimum/maximum protection factors needed with the facepiece type and PAPR airflow. You can even consider consulting occupational exposure limits.
- Comfort and Ergonomics – Look for adjustable components and airflow control for a comfortable fit. Weight distribution in your respiratory protector should minimise neck fatigue.
- Visibility – Opt for integrated headtops or welding shields with large visors and auto-darkening filters.
- Convenience – Look for quick and tool-free maintenance, long battery runtimes, smart monitoring systems and alarm alerts.
- Cost – Balance your budget against key performance factors like filtration efficiency, airflow, battery life, and number of components.
Take Safety and Comfort to the Next Level
Powered respirators revolutionise protection, visibility, and comfort levels for welders. They represent a worthwhile investment in long-term respiratory health and safety.
When used alongside proper protective clothing, welding helmets, and safety training, PAPRs help minimise the many risks faced by welders on the job.
