Aqualung Helix Compact Pro Regulator Set Din

Aqualung Helix Compact Pro Regulator Set Din

Make space in your dive bag with the Helix Compact Pro. Its compact layout combines a balanced second stage with a protected first stage, offering a travel-friendly regulator platform for both warm- and cold-water diving.

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

Features and benefits

• Balanced diaphragm first stage. The balanced mechanism regulates the supply to the second stage as cylinder pressure falls, helping keep the breathing response consistent through the dive.
• 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.
• Automatic inlet closure. The inlet closes when the first stage is disconnected, helping keep water and debris out. Continue to protect the connection with its clean, dry dust cap.
• Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
• 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.
• Comfo-Bite mouthpiece. The silicone palate bridge supports the second stage with less need to clench your jaw, which can make longer dives more comfortable.
• Heat exchange. The heat exchanger transfers warmth from the surrounding water to the valve area, helping counter the cooling that occurs as gas expands.
• Compact travel layout. The compact first and second stages reduce bulk in your dive bag without restricting the platform to warm-water trips.
• Flow channels in the front cover. Side-facing openings reduce the direct force of moving water on the diaphragm, helping the regulator cope with current.

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 × Aqualung Helix Compact Pro Regulators
• 1 × Aqualung Helix Compact Pro Octopus

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.

Which extras are optional?

These items are extra selections and are not automatically included in the base package:

• Aqualung Explorer II Regulator Bag
• Aqualung SPG AL50 Pressure Gauge

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 Aqualung 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.
