Work continues on the creation of a promising means of protecting the respiratory organs of military personnel from harmful substances, chemical and bacteriological weapons.
Its main difference from the classic gas mask is the rejection of the uncomfortable rubber mask. In return, the designers plan to integrate air filters into a protective armor helmet.
The device is called a comprehensive head protection device (CSD). It consists of a breathing mask-like those used by pilots-with filter elements on the sides. The mask is attached to a standard armored helmet made of army equipment "Ratnik" and is supplemented with glasses to protect the eyes.
The prototype of the KSZG "Gas Mask-armor helmet" was created, a patent was obtained for it, writes "Red Star". Two filter elements with activated carbon are placed near the cheeks, the air purification system also includes two micro-fans - they create excess pressure in the under-helmet space. According to the same principle, protection against weapons of mass destruction of armored vehicles is organized: a backstop is created in the internal space, which prevents the penetration of external air.
Tests have shown that the KSZG creates much less inconvenience when used than a gas mask. In addition, the filter elements can be changed without removing the helmet. And fans, among other things, prevent fogging of the visor, blowing it. For additional sealing, a polyamide cape with a sorbing layer and two overpressure valves is used.
The advantages of this utility model: cost-effectiveness for mass production (a number of elements are already in production), which significantly reduces costs; ease of operation due to the elementary connection to the helmet; the time of continuous wearing is increased due to the modularity of the design (in the marching position, the mask is in the unfastened state).
The most important design solutions implemented in the protective device: the integration of a respirator and an armored mask into a single system; modularity, which provides quick replacement of failed filters; reduced local mechanical impact on the head; strong and silent fasteners and connectors, which ensure quick putting on and removing the protective equipment.
