A robust dry chamber with a reinforced diaphragm prevents ice build-up while protecting the regulator from shock. 
An integral heat exchanger around the diaphragm increases the temperature of the gas inside the first stage.
 The classic shape fits most configurations: single cylinder, dual cylinder and decompression block.

The large heat exchange diaphragm support increases the gas temperature in the first stage for improved cold water performance.

Unique overcompensated diaphragm design: During descent, overcompensation allows air at medium pressure in the hose to flow faster than at ambient pressure. This results in better performance at depth.

The DB4+ 1st stage is the APEKS XL4+ regulator, a compact and lightweight 1st and 2nd stage regulator assembly, suitable for diving in all environments, including cold water. Its design and low weight help to reduce jaw fatigue on long dives. The XL4+ is also an ideal stage regulator, perfect for the exploration diver with a large amount of equipment.
