Hollis 200LX DCX Din Regulator Set

Hollis 200LX DCX Din Regulator Set

The 200LX and DCX combine an over-balanced diaphragm first stage with a pneumatically balanced, adjustable second stage. Separate inhalation-effort and Dive/Pre-Dive controls let you set the breathing feel, while the reversible second-stage layout helps a technician configure hose routing to suit your rig.

This package combines the required components listed below, with the available options allowing you to choose the final configuration.

Features and benefits

• Over-balanced first stage. The diaphragm mechanism increases intermediate pressure slightly faster than surrounding pressure as you descend, helping compensate for denser breathing gas at depth.
• Dry environmental chamber. The sealed chamber keeps water and sediment away from the first-stage spring mechanism and supports resistance to freezing in cold water.
• Rotating hose turret. The low-pressure turret turns to follow hose direction, making it easier to arrange hoses without tight bends around the first stage.
• Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
• Inhalation-effort adjustment. The adjustment knob lets you change the effort needed to start a breath, so you can tune the response within the regulator’s operating range.
• Venturi control. The lever changes airflow assistance inside the second stage. Use the pre-dive setting for surface handling and the dive setting as directed in the manual.
• Reversible hose routing. An authorised technician can configure the second stage for left- or right-hand hose entry to suit your equipment layout.
• Flexible breathing hose. The braided hose bends readily around your equipment, helping reduce tension at the second-stage connection.
• Orthodontic mouthpiece. The shaped mouthpiece and supportive bite tabs help hold the second stage comfortably.
• PVD-coated metal trim. The stainless steel ring and control trim have a protective PVD finish to help resist wear and corrosion during regular use.
• Exhaust deflector. The shaped exhaust directs exhaled bubbles away from your field of view.

Setup and compatibility

Connection: DIN. Choose the fitting that matches your cylinder valve and its pressure rating.

What is included in the base set?

• 1 × Hollis 200LX DCX Din Regulator
• 1 × Hollis 150LX Octopus Regulator

The list shows the required components at the displayed default quantities. Your selected sizes, connections, quantities and optional extras determine the final package.

What else will I need?

A pressure gauge is not included in the base package. Check that you have a compatible pressure gauge and the required high-pressure hose, or select an appropriate optional gauge where offered.

A regulator bag is not included in the base package; choose suitable protection for storage or travel if you need it. Check whether your BCD or drysuit supplies its inflation hose, and compare any additional hoses needed for your equipment. Confirm the cylinder connection and have the complete fittings and hose routing checked by a qualified technician.

Care, rinsing and storage

After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.

For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.

Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.

Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised Hollis technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
