4700.010 - Optrel Swiss Air TH3 PAPR Backpack System with Half-Mask

Revolutionary TH3 Respiratory Protection

The Optrel Swiss Air 4700.010 represents a paradigm shift in industrial respiratory protection. Unlike traditional Powered Air Purifying Respirators (PAPRs) that are integrated into specific welding helmets, the Swiss Air system utilizes a standalone ventilated half-mask connected to a backpack-mounted blower unit. This configuration affords the user complete independence in their choice of eye and face protection, making it compatible with virtually any welding hood, grinding visor, or safety helmet on the market. The core of the system is its TH3-certified filtration unit, which captures 99.8% of airborne pollutants, including welding fumes, smoke, aerosols, and viruses, ensuring the highest class of respiratory safety.

Advanced Engineering & Specs

Designed for rigorous industrial environments, the Swiss Air features a high-performance miniature blower system that automatically calibrates airflow based on altitude and temperature. The unit maintains a positive pressure within the half-mask, which not only prevents the ingress of contaminants but also significantly reduces breathing resistance, thereby minimizing user fatigue. The system is powered by a robust lithium-ion battery providing up to 14 hours of continuous operation, sufficient for extended shifts. The control panel, conveniently located on the chest strap, allows operators to monitor filter saturation and battery status, as well as infinitely adjust airflow between 100 and 130 liters per minute.

Universal Fit & Compliance

One of the most significant technical advantages of the Swiss Air is the elimination of mandatory fit testing. The half-mask is constructed from high-tech flame-retardant fabric with an infinitely adjustable headband, designed to create a secure seal for face sizes ranging from XS to XL. This design accommodates beards and various facial structures that typically pose challenges for standard negative-pressure respirators. By delivering clean air directly to the breathing zone via a Y-hose, the system ensures a constant supply of purified air, meeting EN12941 standards for TH3 protection.
