The Apeks XTX100 FST is a high performance balanced diaphragm first stage machined from a solid piece of marine brass, but finished in luxurious satin chrome rather than the polished chrome or PVD. The FST is environmentally sealed for improved cold water performance and reliability as well as to prevent contamination of the main spring and diaphragm.
The XTX100 FST is fitted with four low pressure ports and two high pressure ports set and optimal angles around the main body for the best hose routiung. An optional 5th port is available which features the additional bonus of an integrated heat exchanger (available on the Tungsten, XTX200 and XTX100 first stages only).
Suitable for coldwater use (below 10 C / 50 F).
Compatible with EAN40 out of the box.
- Satin finish.
- Unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
- 2 HP ports and 4 MP ports are angled for optimum hose routing.
- An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
