The MF4047 half-mask gas mask is personal respiratory protective equipment that adopts the self-priming filtration principle. Driven by the user's autonomous breathing, it purifies polluted air through high-efficiency filter elements, providing effective protection against toxic and harmful gases and particulate matter.
Its design fully complies with the technical requirements of standard GB2890-2009 "Non-Powered Air Purification Breathing Apparatus for Respiratory Protection", making it suitable for hazardous working environments in chemical engineering, petroleum, and metallurgy industries.

The standard packaging options include wooden boxes (Size: 245*145*170mm). If required for specific international export regulations, the wooden boxes will undergo standard fumigation processes. For tight cargo spaces, we utilize PE film wrapping or customize packaging configurations to align with special requests.
