Designed for recreational divers and travel enthusiasts seeking high-pressure cylinder security in an ultra-compact footprint, the Scubapro MK11 First Stage Regulator - DIN (1st Stage Only) provides consistent, effortless airflow dive after dive. Featuring a dedicated 300-bar DIN handwheel and an air-balanced diaphragm mechanism in a lightweight chrome-plated marine brass body, the MK11 delivers stable intermediate pressure unaffected by depth or cylinder pressure—making it an exceptional travel companion for warm and temperate diving.
Secure 300-Bar DIN Connection & Balanced Diaphragm Performance
The factory 300-bar DIN fitting threads directly into high-pressure cylinder valves for an ultra-secure, captive O-ring seal rated up to 4350 psi. Its balanced diaphragm design isolates key internal moving parts from the water and debris, delivering smooth, reliable airflow while keeping overall regulator size and travel weight to a minimum.
Features and Benefits
- Dedicated 300-Bar DIN Connection: Direct-threaded DIN handwheel provides a lighter, more secure, and higher-pressure cylinder connection preferred for travel and modern cylinder setups.
- Air-Balanced Diaphragm Mechanism: Delivers constant, effortless airflow completely unaffected by changing tank pressure or recreational dive depth.
- Compact & Lightweight Travel Body: Streamlined chrome-plated marine brass construction minimizes luggage weight and tank-valve profile.
- High-Flow Low-Pressure (HFP) Ports: Features 4 low-pressure (LP) ports—including 2 high-flow LP ports—configured to deliver maximum gas volume to primary and backup second stages.
- Dual High-Pressure (HP) Ports: Opposing HP ports allow convenient placement of a wireless transmitter and an analog submersible pressure gauge (SPG) on either side.
- Sealed Internal Components: Enclosed mechanical layout shields working components from direct exposure to water and contaminants.
