diving gear
The RD-40 is a part of the KSS (Kaliningrad System of diving) equipment designed by the Kaliningrad Development Institute. It is a type of rebreather system and is used as an alternative to open circuit scuba gear. The RD-40 is a closed-circuit oxygen rebreather that recycles the water released by the diver during exhalation and reuses the oxygen within it. It features an oxygen mix supply, a regulator, a full-face mask, a counterlung, scrubber cartridges, and a low pressure gauge. The RD-40 is designed to provide up to 7 hours of dive time, depending on the depth and activity of the dive, and can be used for both recreational and military operations. The RD-40 is an extremely versatile system with its customizable components and easy to use design, making it a great choice for both recreational and military diving operations.
