Περιγραφή
With the introduction of the D420, SCUBAPRO engineers have combined the iconic design
of the original D-Series second stages with the latest advances in breathing performance
technology. They then teamed it with the MK19 EVO balanced diaphragm first stage to create
a 21st century regulator in terms of quality, reliability, performance and style. The D420
features a balanced valve inside a housing supported by a full metal structure. Called the
Progressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing
performance with a natural smoothness comparable to what you might experience breathing
on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable
and allows the LP hose to be connected on either the right or left side for maximum rigging
flexibility. A dive/pre-dive system includes a switch on the top of the casing with a thumb tab
for adjusting the direction of airflow right out of the valve. The highly efficient purge button
is a technical jewel based on a concept that gives the D420 its unique face. Teamed with the
compact, lightweight MK19 EVO offers an environmentally sealed system and a dry ambient
pressure chamber plus a user-friendly LP port swivel turret, this regulator system is uniquely
well-suited to handling cold water and the harsh diving conditions often encountered by
technical divers. This makes the MK19 EVO/D420 more tech-driven than the MK25 EVO/D420,
while serving avid divers and SCUBAPRO brand enthusiasts everywhere
MK19 EVO FIRST STAGE
◊ Designed to be the ultimate first stage for cold water or contaminated diving conditions.
◊ Its design makes it substantially smaller and lighter than the original MK19.
◊ Air balanced flow-through piston in a chrome-plated marine-grade brass body provides
constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
◊ Environmentally sealed system prevents water and pollutants from fouling the inner
mechanism.
◊ Its dry chamber is equipped with a double spring, making it more compact and reliable.
◊ Two opposing high-pressure ports allow the first stage to be positioned either up or down,
plus provide for an optimum hose/transmitter layout.
◊ Swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port
to maximize hose routing options.
◊ Compact size, light weight and superb breathing performance continue in the best
SCUBAPRO regulator tradition.
◊ Ideal first stage for recreational, technical, professional and military divers.
◊ Weight: INT 232, 885g; DIN 300, 665g
◊ Airflow at 2900psi/200bar: (l/min/SCFM): >6,900/244
◊ Intermediate pressure (psi/bar): 133-142/9.2-9.8
D420 SECOND STAGE
◊ Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with
the latest advances in breathing performance technology.
◊ Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a
natural smoothness comparable to breathing on the surface.
◊ Its dive/pre-dive system includes a switch on the top of the case with a thumb tab for
adjusting the direction of airflow right out of the valve.
◊ Its casing design features inner winglets that direct airflow towards the exhaust valve,
creating a dramatic improvement in exhalation effort.
◊ Diaphragm is located in the lower section of the casing to take advantage of the pressure
gradient in the upright position, making breathing even easier.
◊ Reversible hose attachment allows for either left- or right-side LP hose connections for
maximum rigging flexibility.
◊ Large purge button is easy to reach and depress, with or without gloves.
◊ Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while
enhancing ease of exhalation.
◊ Super-flow hose features an oversized bore that allows more air to flow on each
inhalation.
◊ Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all
mouth sizes, from largest to smallest.
◊ CE certified according the latest EN250A European Standards for all diving conditions,
including extreme cold water.
◊ Weight (without mouthpiece): 216g.
◊ Airflow at 200bar: 1800 l/min – 64 SCFM.
S270 OCTOPUS
The S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be
counted on to deliver top-notch breathing performance when you need it most.
◊ Air-balanced valve smooths out the inhalation effort when diving at varying
depths and supply pressures.
◊ Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU
outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving
comfort.
◊ Technopolymer plastic barrel with a metal thread and a balanced valve helps save
weight and provides a surface that ice crystals can’t grab onto when diving in
extreme cold water.
◊ Dive/predive switch prevents free flows when not being used.
◊ Exhaust tee is compact and very efficient in minimizing exhalation effort.
◊ Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone
and features a large cross-section to maximize airflow.
◊ High-viz yellow front cover stands out, making it easy to spot when needed.
◊ High-viz yellow super-flow hose is 39in/1m long with an oversized bore that allows
more air to flow on each inhalation.
◊ CE certified to the latest EN250A European Standards for all diving conditions,
including extreme cold water.
