The P-30ЕX is a compressed oxygen breathing apparatus with a negative pressure breathing circuit. It is used with a full-face mask.
The P-30ЕX is a next generation model of the P-30 breathing apparatus still used by more than ten thousand mine rescuers and firefighters in 20 countries worldwide. Its main features are assured rated duration, small dimension and light weight as well as simple and reliable mechanical design without any electronic components or batteries. When designing this new model, DEZEGA took into account the feedback and recommendations of P-30 professional users all over the world as well as modern regulatory requirements for respiratory protection devices.
As opposed to its predecessor, the P-30EX breathing apparatus is equipped with two fully automated mechanical signal devices that warn users about a lack of oxygen pressure in the breathing circuit and about unacceptable pressure drops. Moreover, in accordance with the EN 145 European Standard, aluminum parts have been totally excluded from this apparatus. All components are made of antistatic materials, and the new ergonomic harness system is resistant to open flame. As well, by using a composite oxygen pressure cylinder, designers have succeeded in keeping the weight low and dimensions small for the P-30EX.
The P-30EX breathing apparatus does not require special tools for complete disassembly or service maintenance. No special lubricants are used for normal operating work. The breathing apparatus is fully compatible with the most popular devices and apparatuses for service checks, and the checking procedure is similar to those already used.
The breathing apparatus is supplied with a ZIR-1 screw coupling full-face mask, which is fully compliant with EN 136 European Standard. The apparatus can also be used with other screw coupling full-face masks that meet EN 136 requirements.
The P-30EX is adjustable with the help of a UKP-5 instrument. We recommend using a KD-8E boost compressor to refill the small-sized cylinders.
