Zeagle Onyx II Regulator



Zeagle Onyx II Regulator

The Zeagle Onyx II Regulator is the sealed version of the 2011 Scubalab Testers Choice regulator, the orginal Zeagle Onyx. With the same attractive finish and outstanding performance as the Onyx regulator, the Onyx II fills the need for those that find themselves in cooler water.

Available in sealed Yoke or sealed DIN

The cold water variant of the Onyx regulator, the Onyx II has the same attractive black finish, 30” braided hose, laser etched logos, and chrome accents with the addition of a dry environmental sealing kit for the 1st stage and black anodized heat sink for the 2nd stage.

It has an internal structure that allows direct airflow through the 1st stage, providing outstanding performance.

Zeagle’s conical precision high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates
The braided LP hose with stainless steel fittings provides high flow and tremendous abrasion resistance while having great flexibility
The compact exhaust tee, advanced black satin chrome finish and light weight construction give the Onyx CW a beautiful presence
Work of breathing at heavy* demand: 1.09 Joule/Liter *198 (60M) depth, 750 psi inlet, 62.5 RMV (liters per minute respiratory volume).

Like all Zeagle regulators, The Onyx 2 comes factory ready for use with EAN/ NITROX to 40% O2.
