Although the XTX40 is a mid-range Apeks regulator, it is still classed as a high performance regulator in independent reviews. The XTX40 comes with all the features of our highly successful XTX50 with the exception of diver adjustable breathing resistance control.
The first stage has four medium-pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose.
Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. Only the narrow exhaust tee is supplied with the regulator.
Optional 5th port is available for sidemount or twin cylinder set ups.
Can be converted from a right-handed hose configuration to a left handed configuration. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician.
Available in yoke or DIN configuration.
Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable.
Suitable for coldwater use (below 10 C / 50 F).
Compatible with EAN40 out of the box.
