Scubapro MK11 EVO 1st stage

The NEW MK11 EVO consists of a balanced diaphragm first stage incorporating a new forged brass body with metal fins to improved heat exchange. The NEW balanced diaphragm MK11 EVO is more compact than its MK11 predecessor, with a forged brass body, thermal fins and plastic bumpers to prevent chafing. It features an innovative dual-spring configuration that contributes to the overall compact size while improving reliability. The MK11 EVO’s two high-pressure outlets are positioned at a 15-degree angle for more comfortable hose orientation, and the four low-pressure outlets are high-flow.
