MK25 G250V REGULATOR SYSTEM
PISTON TECHNOLOGY. The general advantage of a piston first stage lies in its reliability and reduced maintenance requirements, due to an effective but simpler mechanism with less moving parts. More importantly, no other design can reach the high air delivery rate of a balanced piston controlled first stage. It has excellent cold water performance, and is also recomended to use in freezing temperatures.
G250 VINTAGE A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can signi?cantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.
The designation balanced and classic downstream are also distinguishing marks for second stages and again imply ultimate ?ow performance and stability in addition to reliability, simplicity and solid performance.
