Product Overview
The Hollis 150LX + HO2 brings together a dedicated oxygen first stage, balanced second stage and Miflex braided hose for suitably trained divers building an oxygen decompression setup.
The HO2 first stage uses a non-balanced flow-by piston design, with four low-pressure ports and one high-pressure port. Its green DIN handwheel and oxygen markings help identify its intended gas service, complemented by the green hose and second-stage detailing.
Key Features
Dedicated oxygen configuration: compatible with up to 100% oxygen when maintained in the required oxygen-clean condition.
HO2 piston first stage: a straightforward non-balanced flow-by design with a chrome-plated brass body.
Pneumatically balanced second stage: the 150LX includes a dive/pre-dive Venturi lever.
Green identification details: green DIN handwheel, hose and second-stage trim identify the oxygen configuration.
Stainless steel components: the second-stage front ring, packing nut and end cap are made from 316 stainless steel.
Miflex braided hose: supplied to connect the first and second stages.
Orthodontic mouthpiece: includes dual-colour bite tabs.
