The Avec S-97 protective half-mask used with a suitably selected filter type ensures maximum and long-term protection of the respiratory organs depending on the usage conditions.
In combination with an appropriate filter, the mask provides safe protection against organic vapor, acidic gases, ammonia, highly toxic gases, radioactive particles and particularly dangerous bacteria and viruses.
The extremely lightweight half-mask is made of high-quality medical-grade silicone rubber. It does not irritate sensitive skin. Depending on the thread type, the Avec S-97 half-mask comes with a wide range of filters with a curved thread Rd 40x1/7" (EN 148-1) or OZ 40x4 (GOST 8762-75). All types of protective filters in the AFC-20 and AFC-25 series are suitable for the half-mask.
