Apeks Nitrox XTX200 Regulator

The Nitrox variant of the XTX200 regulator has been laboriously oxygen-cleaned in Apeks specialised labs and fitted with an M26 EU standard connection. This allows it to be used with 100%-Oxygen Nitrox blends. Enjoy longer bottom times and fewer decompression stops.

The XTX200 itself is among one of Apeks’ most advanced regulators. The FSR 1st stage’s over-balanced diaphragm ensures it delivers consistent and clear air supply even in extremely deep water. Environmentally sealed, the Nitrox XTX200 resists ice buildup allowing it to perform effortless in icy cold water. This also has the benefit of protecting your regulator from silt or bacterial ingress which can contaminate your air supply.

The XTX200 2nd stage is pneumatically balanced. This means that even when your tanks are running low of pressure breathing remains relaxed and unlaboured so you can breathe easy throughout your dive. A venturi control and free-flow dial allows you to configure your breathing effort to suit your needs and taste.

The XTX200 offers further configuration options with its Diver interchangeable Exhaust. One exhaust is small and convenient while the second is larger, offering superior bubble dispersion, ideal for underwater photographers or divers with wider faces.

The Comfo-Bite mouthpiece features a bridge that sits across your palate, this helps to support the regulator eliminating jaw fatigue while also preventing dry mouth during long dives.

The XTX200 Regulator is designed to stun, both in terms of outright performance and stunning chrome aesthetic. There is no doubt that the XTX200 is one of the most impressive technical regulators available today.

In Europe the Apex Nitrox Regulators are sold with an M26 connection.

  • Easy-Push Purge Button - The XTX 2nd stage features an enlarged purge button making it easy to operate. A 2-stage progressive purge is used - press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge.
  • Venturi Lever - The large venturi level is easy to locate and use and any time and allows you to control how much breathing effort is required to receive air.
  • Opening Effort Control - Let your regulator breathe at its best with the large Opening Effort Control for maximum breathability.
  • Anti-Bacterial Design - The XTX 2nd stage has been designed with active anti-bacterial protection. The additive kills MRSA, protects against E-Coli, bacteria and fungi, ensuring you stay safe in hostile underwater environments.
