XL4+ Regulator

£340.00 RRP £401.00 In Stock

Brand: Apeks

Model: XL4+ Regulator

SKU: 77373-1

Please note: This item cannot be shipped outside the European Union - learn more

The Apeks XL4+ Regulator is a white version of the popular, compact, cold water XL4 Regulator. With one small adjustment, a second HP Port, the XL4 Plus is more practical for divers who want to use an analogue gauge and a wireless transmitter.

Who is the XL4+ For?

The XL4 + is tested for cold water while keeping lightweight for travelling divers. A small 2nd stage is perfect for longer dives to reduce jaw fatigue and reduce bulk on a stage cylinder.  The XL4+ is perfect for divers who want a regulator they can use in cold waters that isn't heavy so they can use it as a holiday regulator too.

Compatibility

Any Apeks Octo is compatible with the XL4+ but the XL4 Octo is best if you're looking to build a single cylinder setup. Any LP Inflator Hose will fit the XL4 and Apeks' Tech Gauge and Hose is the perfect SPG for a single cylinder set.

1st Stage

  • Compact machined 1st stage based on the expedition tested Apeks DS4 platform.
  • Break through, innovative over-moulded first-stage endcap & environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage.
  • Large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside the 1st stage, resulting in improved cold water performance.
  • Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.

 

2nd Stage

  • Compact and lightweight 2nd stage improves comfort and helps reduce jaw fatigue on long duration dives.
  • High performance pneumatically balanced lever operated poppet valve.
  • Large, over moulded self-flushing and controllable purge button.
  • Ergonomic Venturi lever is easy to use and locate.
  • White flexible nylon braided hose has better cold water performance than traditional rubber hose.
  • Standard metallic hose connection for interchangeability.
  • Comfo-bite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place.
  • Re-useable mouthpiece clip makes it simple to change mouthpieces in the field.
  • Durable and flexible rubber exhaust tee provides excellent bubble diversion.
  • UV inhibitors to help prevent discolouration of the white materials.

Apeks XL4+ Regulator - Features

FeatureProduct Specification
Adjustable Inhalation
?
This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air. Close.
No
Adjustable Venturi
?
The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing. Close.
Yes
Cold Water Rated
?
Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.

Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.


EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C. Close.
Cold & Warm Water
Environmentally sealed
?
Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)

Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming. Close.
Yes
First Stage
?
Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.

Balanced regulators are not affected by the cylinder pressure or depth.

Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers. Close.
Over-balanced
High Pressure Ports
?
High pressure ports supply the pressure gauge and wireless transmitters for dive computers Close.
2
Low Pressure Ports
?
Low pressure ports supply the 2nd stages and inflator hoses Close.
4
Service Information
?
All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.

Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run. Close.

Weight in Grams (approx)

The weight includes the first stage (DIN fitting), hose and second stage. Close.
