Scubapro’s AIR2: Updated Design and Radically Improved Performance
Scubapro introduced the octo/inflator to diving almost thirty years ago with the introduction of the original AIR2. Since then, this popular octo/inflator has undergone four generations of design innovation. For 2015, the 5th generation AIR2 offers divers even more in both performance and ease of use.
In terms of performance, Scubapro engineers have managed to reduce the new AIR2’s WOB (work of breathing) by half, creating an octo/inflator that delivers air as easily and smoothly as most primary second stages.
According to recent EN250: 2014 lab tests, when teamed with a MK25 first stage, at a depth of 30m/99ft, using a supply pressure of 50bar/725psi, the new AIR2 delivered WOB of only 1.34 j/l (the 4th generation AIR2’s WOB, under similar test conditions, was 3.55 j/l). This substantial improvement in work of breathing is due to the reduction of resistance on both the inhalation and exhalation sides of the breathing cycle, making it easier to not only take in air, but also to expel air, both of which are critical in keeping divers from getting panicked and over-breathing in emergency situations.
The new AIR2 is also easier to use. The flexible purge cover is large and easy to locate, allowing for quick clearing when the time comes to take a breath. In addition, a new Dive/Pre-Dive switch lets divers detune the octo when it’s not being used, eliminating free flows, while enabling it to deliver generous airflow when needed.
The AIR2 not only offers superb performance as a backup regulator; design upgrades have also improved the user-friendliness of the BC inflator/deflator system. Larger inflate and deflate buttons can be easily differentiated by both colour and touch, improving safety on both ascents and descents. The power inflate button features a lighter lever so less load is required to initiate inflation. Both inflate and deflate controls are positioned on top of the housing, making it easier to operate the buttons when breathing off the octo without having to change hand positions.
THE AIR2 (5th Generation) AT-A-GLANCE
- Radically improved WOB of 1.34 j/l, compared to a WOB of 3.55 j/l for its predecessor (Tested using a MK25 first stage at a depth of 30m/ 99ft, using a supply pressure of 50bar/725psi.)
- Improved WOB meets or exceeds the new EN250:2014 octopus/AIR2 requirements. The new AIR2 will be CE certified according to Annex A warm water test directions.
- Test-proven breathing performance and cracking effort compares favorably to traditional downstream second stages, and in fact surpasses many in ease of breathing.
- Breathing performance remains consistent at any air supply pressure, resulting in smooth and dependable airflow.
- New Dive/Pre-Dive switch allows for effortless air delivery, plus enables the diver to detune the unit when not in use, eliminating free flows.
- Flexible S560-style purge cover is easy to locate and depress for quick clearing, even when wearing thick gloves.
- Power inflate and deflate buttons are positioned on top of the housing when the AIR2 is in the diver’s mouth, making it easier to control buoyancy.
- Power inflate button, which is the same as on the new BPI, features a lighter lever so less load is required to initiate inflation.
- Larger inflate and deflate buttons can be differentiated by colour and by touch due to their different shapes and sizes, improving ascent control and safety when inflating or deflating the BC.
- Large bite tabs on mouthpiece guarantee a secure grip in high-stress situations.
NEW REGULATOR TESTING STANDARDS
The new European EN250-2014 regulator testing standards were slated for approval in July 2014. As part of these new test standards, the following changes have been made:
- WOB test parameters have been adjusted down to 2.5 j/l (previously 3.0 j/l).
- Regulator cold-water tests are run with both single (62.5 l/m for 5 min @ 50m) and simultaneous breathing (560 l/min for 2 min @ 30m/99ft); with water temperature of 2°C
Scubapro regs have already been tested by RINA, the Italian certification board, according to these new standards and have been given the green light. “EN250A” markings will follow next fiscal year with the in-line change of marked parts on Scubapro regulator products.
The AIR2 is available at authorised Scubapro dealers and fits on all Scubapro BCD’s.
RRP: £135

Whether you are a beginner or a professional diver – with the three new main regulators from DYNAMICNORD, everyone will find their favourite regulator. They all look super stylish.
Excellent performance with the TR-80
Quality and performance are the be-all and end-all for regulators. It is not for nothing that the TR stands for Tec Reg. The innovative design of the TR-80 guarantees absolute reliability – even in ice-cold waters.
Perfect breathing effort at 0.8 J/l / certified for diving in waters below 10 degrees / structural design made of solid brass for best cold protection / membrane-compensated design with dry seal of the first stage / reduced exhalation effort thanks to optimized exhalation membrane and bubble deflector / adjustable Venturi (dive/predive) and adjustment knob for individual inhalation comfort / innovative design of the front cover prevents free-flow in strong currents or when diving with scooters / design made of sandblasted brass, matt chrome finish / 2 HP and 4 LP outlets / mouthpiece made of high-quality, anti-allergic silicone for maximum comfort.
Amazing underwater adventures with the IR-50
The IR-50 is the top regulator for advanced and experienced divers. Natural breathing is the essence of this regulator.
Ideal breathing effort at 0.8 J/l /certified for diving in waters below 10 degrees / compensated membrane / adjustable venturi (dive/predive) and adjustment knob for individual inhalation comfort/ outlet valve and deflector for minimum exhalation effort and reduction of bubbles on the face / design made of sandblasted brass, matt chrome finish / 2 HP and 4 NP outlets / mouthpiece made of high-quality, anti-allergic silicone for maximum comfort.
The Workhorse – our CS-30
For diving centres and diving beginners – the workhorse stands for strong construction, reliability and robustness. Perfect for your training.

Maximum freedom of movement and outstanding comfort
The SP series neoprene suits deliver incredible diving comfort to even the most demanding divers. Fabulous style included. Designed and engineered in Germany.
The smart 3D cut and the pre-shaped arms and legs not only ensure flexibility and a perfect fit, but also help you slip into the suit with ease. Cuffs on the arms and legs guarantee perfect sealing, which is further enhanced by the flap on the back zipper.
Zippers at the wrists and ankles provide additional comfort and ensure easy donning and doffing. The small neck zipper adds another layer of comfort.
The neoprene ribs in the back of the knees and crook of the arms are unique. The clever concept ensures optimum comfort when bending the arms or legs.
Shoulder and knee protectors protect the suit in high-wear areas. The small computer safety strap holds the device in place. The SP suit series is available for men and women in 5 & 7mm and offers a wide range of sizes including numerous intermediate sizes.
Every day, DYNAMICNORD works to keep its environmental impact as low as possible. Only the best available neoprene is used for the SP series of neoprene suits. It goes without saying that the neoprene is made from limestone. It is sourced from nature and has less negative impact on the environment. Furthermore, Carbon Black, one of the main components of neoprene, is pyrolysed from used tires. This reduces energy consumption and cuts CO₂ emissions by 200 grams per neoprene suit. Innovative dyeing machines reduce water and energy consumption during production by 60%.
DYNAMICNORD’s R&D department is constantly testing recycled materials and other next-generation sustainable components to become even more eco-friendly in all areas.
The different models in the SP series are now available from DYNAMICNORD dealers and in the online store.
