Optrel Swiss Air PAPR Respirator System Overview
The Optrel Swiss Air PAPR respirator system is a half-mask powered air-purifying respirator that filters ambient air and can be worn under virtually any welding helmet. A lightweight belt or backpack blower draws air through a HEPA filter rated to the TH3 class and delivers about 99.8% clean air to a positive-pressure half-mask through a hose.
As the Optrel Swiss Air PAPR, this Swiss Air half-mask PAPR is a compact Optrel half-mask respirator that offers three airflow levels from roughly 100 to 130 liters per minute with automatic airflow calibration and temperature compensation, and its lithium-ion battery runs up to 14 hours. As a Swiss Air welding respirator, the Optrel Swiss Air blower lets you add powered respiratory protection while keeping the welding helmet you already use.
Despite its name, this is a PAPR that filters ambient air, not a supplied-air or airline respirator. Wear it under an Optrel helmet such as the Optrel Panoramaxx CLT or the Optrel e684, and browse it in powered air-purifying respirators, respiratory protection, and welding respirators.
What This System Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Keep your current welding helmet | Purpose-built | Half-mask fits under virtually any helmet. |
| Welding fume and dust | Strong | HEPA TH3 filter removes about 99.8% of particulates. |
| All-day comfort | Strong | Light blower; three airflow levels; ~14 hr battery. |
| Gases or vapors | Not suitable | Particulate only; use a rated cartridge system. |
| Oxygen-poor or emergency air | Not suitable | Filters ambient air; not for emergency atmospheres. |
A respirator only protects within a complete, matched, compliant system. The Swiss Air is a PAPR: it filters ambient air through a particulate HEPA filter, so it captures welding fume and dust but not gases or vapors, which need a rated cartridge system. It is not a supplied-air or airline respirator, and because it purifies ambient air rather than supplying it, it is not for IDLH or oxygen-deficient atmospheres, which require an SCBA or a supplied-air respirator rated for those conditions. The TH3 rating is the highest class on the EN powered-respirator scale; confirm the OSHA assigned protection factor for your facepiece and configuration. Verify airflow before each use, keep the filter and battery in service, use only approved components, and run the system within a written program under OSHA 29 CFR 1910.134. Learn the rules in our OSHA 1910.134 respiratory protection guide and the respiratory protection complete guide.

Frequently Asked Questions
What is the Optrel Swiss Air PAPR respirator system?
It is a half-mask powered air-purifying respirator. A lightweight belt or backpack blower draws ambient air through a HEPA filter and feeds a positive-pressure half-mask through a hose. The half-mask fits under virtually any welding helmet for respiratory protection.
Is it a supplied-air or airline respirator?
No. Despite the name, it is a powered air-purifying respirator that filters ambient air with a HEPA filter and a blower. It does not connect to a remote compressed-air source, so it is not a supplied-air or airline respirator; treat it as a PAPR for program purposes.
What does the filter capture?
The Swiss Air uses a HEPA filter rated to the TH3 class that removes about 99.8% of welding particulates, smoke, aerosols, and dust. It is a particulate filter, so it does not protect against gases or vapors; match your respirator to the exposure.
What airflow and runtime does it provide?
It offers three airflow levels from roughly 100 to 130 liters per minute with automatic airflow calibration and temperature compensation. The lithium-ion battery runs up to about 14 hours per charge, which typically covers a long shift.
What comes in the kit?
The 4700.010 kit typically includes the blower unit, a chest-mounted remote, one filter and one pre-filter, a spark protector, the air hose, the battery and charger, and a backpack, plus the owner's manual. Confirm the exact contents on the listing.
What assigned protection factor does it provide?
The filter carries the TH3 class, the highest class on the EN powered-respirator scale. The OSHA assigned protection factor depends on your specific facepiece and configuration, so confirm it against the Optrel documentation and your written respiratory program.
Can I wear it under my own welding helmet?
Yes. The positive-pressure half-mask is designed to fit under virtually any welding helmet, so you can add powered respiratory protection while keeping the helmet and auto-darkening filter you already use. Confirm clearance with your specific helmet.
Does it protect against gases or vapors?
No. The HEPA filter is for particulates such as welding fume and dust. It does not filter solvent vapors or acid gases. If your work involves those exposures, you need a respirator and cartridge or system rated for them, matched to the hazard.
Can I use it in an oxygen-poor or emergency atmosphere?
No. Because a PAPR filters ambient air rather than supplying it, it is not for oxygen-poor or immediately dangerous atmospheres. Those require respiratory protection rated for such conditions, and you must confirm the environment first.
Does the blower warn me of low airflow?
The Swiss Air monitors airflow and compensates automatically, and the chest-mounted remote lets you check and set the level. Always verify airflow before use and respond to any warning right away, since protection depends on adequate airflow to the mask.
Do I need a written respiratory program?
Yes. Powered air-purifying respirators are used within a written respiratory protection program under OSHA 29 CFR 1910.134, including training, medical evaluation, and maintenance. Follow the Optrel manual for assembly, use, and inspection.
How do I maintain it?
Inspect the mask, hose, filter, pre-filter, spark protector, blower, and battery before each use, verify airflow, replace the filter and pre-filter per exposure and the Optrel schedule, and keep the system clean and charged. Follow the Optrel manual for intervals and part numbers.

Best thing ever - put it on at the start of the day, don't take it off till the end!
I've had this thing for about a week now, using it every day to weld, grind and cut.At this point, I can't imagine how I've lived without it. The battery lasts more than all day. And best of all, I can't smell any grinding dust or weld bits. Let's me concentrate on what I'm doing instead of constantly futzing with a respirator, holding my breath, thinking I can get away with this one cut / grind / weld without my protective gear.. .. . I also just turn it on and leave it on the whole day.The plastic is alittle bit flimsy, but that also makes it light. I can also buy replacement parts if the hose or the mask or something breaks.I hope it lasts a long time. If it lasts a year at least, I'd likely buy another one if this one breaks.

Great clean ventilation but...
I make recycled art and use a plasma cutter. I was looking for a respirator that was comfortable under my helmet and not restricting breathing.Added to review 12/5/22Does anyone else have an issue with the 4800.400 main filters plugging after 30 hours of cut time?I’m about to order another set of 2/$39. So this will be 4th and 5th main filter purchased.I replace the pre filter before cutting.I think read this filter will need to be changed every 6 months. I’ll go back and refer to my manual on that.10/10/22I’ve used it twice and this piece broke off in my hand when I slid it to change the filter. Hopefully they replace it.

Invest in your health and save your lungs
I can't say enough good things about this PAPR.Other reviewers gave this a negative review based on the battery tab being easily broken. The filter has the same latch mechanism. It is light weight and looks like it can be broken easily. IF you have this knowledge it's not an issue because you will be careful. This item cannot be returned...I suggest you use care when disconnecting the battery or filter.Also, I would stock up on the pre filters. Its much cheaper to dirty the pre filter instead of the $45 carbon filter.

Many small flaws
Good air but the delicate plastic pieces that break off in key locations ruin this thing. Especially for the price which I believe is technically fourteen hundred on this model. I mean the battery life is amazing, running all day and losing one bar on its indicator, and the protection is very good. It's Pretty disappointing in my opinion. I'd never recommend the product to someone. But I'd definitely recommend papr in general for anyone welding. Which I use this for. Unfortunately papr gear is hilariously overpriced always being around two grand and having extremely overpriced replacement parts such as two hundred to four hundred dollar basic batteries. So this is currently the cheapest you can get at the moment.

BUYER BEWARE: NO RETURNS ON THIS PRODUCT ON AMAZON
Purchased this unit brand new and unfortunately it did not fit my face. I literally took the facemask out of the box and did not unbox anything else. Being a smaller person, the unit was much too large for my face. So I went to return the item and apparently hidden in the Amazon details was that the item was NOT RETURNABLE. This is deceptive and really on an item of this cost, a little leeway should be allowed as its very much like clothing, if something does not fit the purchaser, its useless to them. On an item over $1,100, this is inexcusable. No other retailer of this system has a NO RETURNS policy. BUYER BEWARE!!
