Application:
The closed circuit apparatus W2000 is designed for protecting the wearers breathing circuit when work is carried out in the irrespirable atmosphere, for example oxygen deficiency or toxic gasses after fires or explosions.
The apparatus is predominantly aimed at Mines Rescue Teams. Together with the well fitting full face mask, it corresponds with European Standard EN 145.

Advantages:
- simple operation - the modular construction of W2000 enables its simple assembly, disassembly and cleaning after use, with most maintenance and servicing carried out without tools
- better comfort of breathing - positive pressure in the breathing system of the apparatus protect against accidental ingress of harmful substances from the outside environment entering the breathing circuit, use of ice cooler ensures a low inspired air temperature
- better comfort of use - with an ergonomically-shaped carrier and comfortable carrying straps, general comfort of use to the user is increased, flexible hoses ensures that the apparatus can be easily removed and replaced with the mask in place, to negotiate narrow areas or confined spaces
-
better functional checking of apparatus - is achieved with the use of Electronic
Supervision System ESN-1 which has been designed for continuous pressure reading of the oxygen cylinder coupled with simultaneous monitoring of the operation and
supervision of the apparatus, safety of use is increased due to the warning system, which begins operating when there is a terminal oxygen pressure left or the apparatus develops a problem
The ESN-1 monitoring system shows a clear display of oxygen cylinder pressure, analogue oxygen consumption index as well as time of start of apparatus operation.
