T3 Regulator

£1,293.00 RRP £1,349.95 Out Of Stock

Brand: Atomic

Model: T3 Regulator

SKU: 46361-1

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

The Atomic Aquatics T3 Regulator is all about being the absolute best - The regulator is made from serious high grade materials that are light, strong, high performing and corrosion resistant. The lengths that Atomic go to in order to achieve such high performance is incredible.

The Atomic T3 extends the impressive two year service period to a unheard of three year or 300 dive service interval and the regulators are even covered by a lifetime warranty. The use of such high grade materials and some clever patents such as the 'Seat saving orifice' all helps to extend the period between service centre visits without affecting the extremely high reliability and performance.

The design changes from the previous T2 models have been scrutinised to shave off as much weight as possible to make the regulators one of the lightest full size, high performance regulators available. The A-Clamp frame in particular has seen huge weight reductions and is no longer a hindrance for travelling divers compared to DIN valves. The first and stage components are precisely machined from solid titanium billet. Even the comfort swivel is made of lightweight titanium rather than coated brass or steel.

The first stage is a high flow and performance balanced piston with environmental seal to provide full cold water and contamination protection. The sleek and compact first stage is fitted with two high pressure ports, four low pressure ports around the circumference of the swivelling turret and a low resistance, high flow low pressure port on the end of the turret. This is the default port for the primary second stage.

The second stage has been fitted with redesigned internal components to further reduce the weight of the regulator, increase gas flow and reduce breathing resistance. The external titanium components have been treated with a PVD coating to significantly increase the scratch resistance. The T3 has a diver adjustable inhalation controller on the side of the regulator to increase the breathing resistance if required. A dual density silicone mouthpiece combines an ultra soft silicone mouthpiece with harder density teeth tabs that helps to prolong the life of the mouthpiece. The exhaust covers do an excellent job in directing exhaled gas away from the divers face and field of view. Previous features such as the seat saving orifice and automatic flow control have been brought forward into the T3.

 The 'seat saving orifice' works to remove the pressure off the second stage low pressure seat when the regulator isn't being used. In a normal regulator the orifice is always being pushed into the soft low pressure seat whenever the valve isn't open to let air into the second stage. Over time the orifice creates a grooved ring in the seat which eventually makes the second stage unreliable and start to let air through even when closed. The seat saving orifice takes the pressure of the seat when not in use but is pushed into place as soon as the regulators are pressurised. This significantly improves reliability and the required service intervals of the regulator.

Unlike most regulators which have a manually adjustable venturi lever the T3 regulator is fitted with 'automatic flow control' (AFC) which automatically controls the flow of air inside the second stage housing, subtly adjusting the performance as the diver descends and ascends to provide the perfect balance between performance and reliability.

The Atomic T3 is supplied in a deluxe padded regulator bag and is compatible with nitrox mixes up to 40%.

Atomic T3 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
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 flowingClose
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
2nd Stage
An Unbalanced second stage is simply a lever operated valve that is opened and closed as the diaphragm is pulled inwards by the vacuum that is created when the diver inhales. An unbalanced second stage is affected by increased pressure at depth, slightly increasing the effort required to open the valve. A Balanced second stage overcomes the effects of increased pressure by utilising a balancing chamber. This chamber takes some of the work away from the spring mechanism, allowing a smaller spring to be used which results in an easier breathe. As the chamber uses air to balance the valve it maintains the same resistance as the diver descends and ascends, keeping the inhalation effort the same.Close
Service Info
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
3 Years - 300 Dives
1st stage HP Ports
High pressure ports supply the pressure gauge and wireless transmitters for dive computers. Most 1st stages will have atleast one 7/16" HP Port but two allow for a transmitter and SPG.Close
1st Stage LP Ports
Low pressure ports supply the 2nd stages and inflator hoses. Most will have the standard 3/8" LP port but some 1st stages also have a hi-flow 1/2" LP Port.Close
1st 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
Weight (g)
The weight includes the first stage (DIN fitting), hose and second stage.Close

The best money can buy

The atomic T3 is a high spec regulator.

Its the best money can buy ergonomically made and rigorously tested.

It has a smooth flow and is super comfortable with it ball joint connection.

It's perfect for when I travel as it's super light weight. And come it's a luxury carry case.

It's parts of so well made that you only have to get it serviced every 3 years. I woukd still get it checked over by my an authorised Amtoics technician.

Amazing regs

Amazing regs ... I am lucky enough to have recently become the owner of an Atomic T3 + T2 Octopus set after purchasing the M1 + M1 Octopus. Check out my reviews of those regs here on Simply Scuba. The T3 is the same plus more, truly unbelievable p
