MSA Safety Advantage 420 Series Half Mask Respirator Mask, Size S Hypoallergenic

This respirator mask provides breathable facial protection for workers in technical environments where particulate filtration and a secure seal are required. Designed as a half-facepiece, it combines a soft silicone rubber facepiece with supportive yoke components to offer a Compact solution for tasks where repeated donning and doffing and extended wear are common. The design suits controlled industrial settings and maintenance operations in automation, electronics, electrical and mechanical trades.

• Small profile facepiece for reduced obstruction during tasks • Hypoallergenic materials minimise skin irritation for prolonged wear • Polypropylene and neoprene elements for Durable chemical resistance • Nylon and polyester straps deliver stable load distribution • Polyoxymethylene yoke maintains alignment under stress • Silicone and liquid silicone rubber ensure a flexible seal

• Suitable for PCB assembly and soldering tasks in electronics • Ideal for electrical maintenance in confined cabinets and switchgear • Used for mechanical workshops performing metal finishing and grinding • Can be used in automation lines requiring frequent operator access

The face-adjacent components are MADE from silicone rubber and liquid silicone rubber and are specified as hypoallergenic to limit skin sensitivity during extended use.

A polyoxymethylene yoke combined with nylon and polyester straps provides dimensional stability and consistent alignment under repeated motion.

It complies with multiple international standards including EN 140, NIOSH, GOST and AS/NZ, indicating cross-region regulatory acceptance for half-mask respirators.

Structural elements employ polypropylene and neoprene for resistance to common workshop contaminants while maintaining component longevity.
