|This rebreather is developed in 1966. Basically
it is intended for carrying out of salvage-operations under
water on depths up to 120 meters.
The device is part of the complete set light diving
equipments SV SPL and can work with the help of a breathing mix
supplied by a hose, and also functions independent, using
nitrogen-helium-oxygen a mix from a cylinder in the device.
The maximal depth of immersing - 120 meters. Operational at
average work - 2,5 hours. The respiratory system is filled by a
gas mix through lung and the automatic device. Except for that
the design stipulates periodic washing of respiratory system
with the help of the time mechanism, and also a light signal
(lantern FAS-1) about pressure drop in a hose.
