Product Description


Apeks ATX40 ATX40 Regulator Set, Stage 3

The Apeks ATX40 regulator set represents excellent valve for money, an excellent breathing regulator that is compact and lightweight. The ATX40 regulator has been a workhorse in the UK and the number that can be seen at dive sites shows the ATX regulator has definitely earned its stripes. The ATX40 Octopus is the same in spec to the ATX40 second stage but comes with bright highly visible front cover. The ATX40 stage 3 regulator set is made complete with the DS4 first stage, the benchmark in first stage reliability and simplicity the DS4 just works. The Apeks ATX40 Octopus Regulator Set is ideal for the entry level diver that is looking to future proof their regualtor system.

The ATX regulator manual can be found here.
