Overview
The MF31 full-face ball mask for respirators is the main component of a positive-pressure self-contained open-circuit compressed air respirator. To protect the user's face and respiratory organs. The full-face ball mask for respirators is mainly used with the RHZK6.8/30 positive pressure fire-fighting air respirator. It can also be used in conjunction with the air supply devices of other positive-pressure self-contained open-circuit compressed air respirators. It is widely used in fire protection, chemical industry, metallurgy, shipbuilding, military operations, anti-terrorism and public emergencies and other workplaces for self-protection and other rescue operations.
Features
The mask is made of silicone rubber injection molding. The sealing frame of the mask body is designed according to the head shape of Chinese adults. It adopts a folded edge form, which is easy to air-tight and comfortable to wear. It can be worn by more than 95% of adult citizens.
The spherical lens of the mask is made of polycarbonate, and the surface coating has a wide field of view, good optical and impact resistance properties. Baoming uses a water-blocking cover structure, which has good brightness protection performance.
