Optrel Swiss Air PAPR Respirator
Battery-Powered Powered-Air-Purifying Respirator (PAPR) with Secure Silicone Half-Mask
The Swiss Air Tight-Fit PAPR by Optrel delivers fresh, filtered air through a rechargeable blower-unit, paired with a snug silicone half-mask for maximum respiratory protection. Designed for welding, grinding, cutting and other dust- or fume-heavy work, it is certified to NIOSH PAPR-100N standards and gives you durable, reusable protection in demanding shop conditions.
Whether you prefer a hood, a welding helmet, or just need clean air with low breathing resistance, Swiss Air adapts — giving welders, fabricators, and industrial workers the flexibility and protection they need.
The swiss air is PERFECT for people that don't need a full time dedicated PAPR set up. It fits over your mouth directly, allowing you to wear your regular lid, or even no lid at all. The swiss air will essentially make your existing helmet in to a PAPR set up! No need to buy a second helmet!

Tight-Fit Silicone Half-Mask: Available in S, M, L sizes — secure seal ensures TM3 protection (or TH3 when blower is on) for high-hazard environments.
-
Positive-Pressure Clean Air Supply: Air delivered by a compact blower unit worn on the back — supplies fresh air even in polluted environments and reduces breathing resistance.
-
Adjustable Airflow Settings: Several airflow levels (e.g. min 120–140 l/min depending on mode) to match activity intensity
-
Long-Duty Battery: Rechargeable lithium-ion battery provides around 6–10 h run time depending on airflow level
-
Lightweight & Ergonomic: Blower unit + filter system designed for comfort — reduces neck/head fatigue compared to traditional respirators
-
Built-in Alarms & Controls: Audible / visual alarms for low battery, clogged filter, or low flow; easy-to-use control panel; automatic flow regulation and altitude/temperature compensation
-
Certified Protection: Meets NIOSH PAPR-100N (for North America) when used with approved filters and mask types
