Professional MSA 3S full face respirator with EN148-1 thread connection for filters, compressed air, and turbo filtering devices. Over 50 versions available in standard and small sizes with multiple harness options. EN 136 class 3 certified.
The MSA 3S Full Face Mask with EN148-1 Thread Connection is a professional-grade respiratory protection device designed for industrial and hazardous environments. With over 5 million units sold worldwide, this mask represents the most successful full face respirator design in the industry. The mask features a durable polycarbonate lens that provides impact resistance and an enlarged field of vision, ensuring clear visibility in critical work situations. The face blank is constructed from a special rubber compound that creates a softer, more comfortable seal while remaining unaffected by lotions or creams, combined with a deeper chin stop for a snug, secure fit.
This normal pressure full face mask operates with an EN 148-1 standard thread connection, making it compatible with filters, normal pressure compressed air breathing apparatus, compressed airline breathing apparatus, and turbo filtering devices. The mask features an advanced harness system that allows for quick donning and removal without adjustment, providing a pressure-free fit with a carrying strap for convenient chest-mounted transport. The exhalation valve is strategically positioned at the lowest point of the mask, featuring a large cross-section that minimizes exhalation resistance. Both the valve disc and valve cover are easily replaceable for long-term durability and maintenance.
The MSA 3S offers exceptional versatility with over 50 available versions to suit virtually all applications and user preferences. It is available in both standard and small sizes and can be equipped with various harness options including rubber, silicone, Nomex, and EZ-don variants. The mask includes an inner mask option that optimizes air flow, prevents lens fogging, and reduces dead space effectively. All MSA 3S full face respirators are tested and certified according to EN 136 class 3 standards, ensuring compliance with the highest safety regulations. An optional speech diaphragm permits excellent communication between users, and the mask can be configured as part of mask-helmet combinations for specialized applications.
