3M 4251+ 4000+ Series Half Mask Respirator is a high-quality respiratory protection device designed for industrial, laboratory, and commercial use. Constructed from durable thermoplastic elastomer materials and featuring blue and white coloration, this one-size mask provides robust defense against a range of gases, vapours, and particulate hazards commonly encountered in mechanical, electrical, and automation environments.

The respirator incorporates permanently attached large carbon filters coupled with bonded particulate filters to deliver superior filtration without requiring separate components. Twin inhalation valves minimize breathing resistance, enhancing user comfort during extended wear periods. Designed to meet the EN 405:2001 + A1:2009 standard, this mask ensures compliance with recognized European safety requirements for respiratory protective devices.

Its lightweight construction and disposable design eliminate maintenance and assembly needs, making it efficient and convenient for workplaces with varying personnel. The half mask fits a wide range of face sizes, reducing inventory complexity for employers and providing consistent protection for users.

Applications for this respirator include protection against organic vapours in industrial settings, safe use during mechanical and electrical tasks involving hazardous substances, and maintenance of breathable air quality in engineering and electronics sectors. It is explicitly not intended for oxygen-deficient atmospheres (below 19.5% oxygen).

Proper storage is critical for maintaining mask integrity; it should be kept away from high humidity, direct sunlight, and extreme temperatures. The shelf life of the mask is up to three years when stored correctly.

This half mask offers versatile protection against gases, vapours, and particulate hazards in industrial environments. Equipped with twin inhalation valves to reduce breathing resistance and improve comfort. Large bonded carbon filters permanently attached provide superior combined filtration.
