    Aqualung Core Supreme Regulator -  (Available in DIN o A-clamp)

    The cold water, environmentally sealed version of the Aqualung Core series regulators, the Aqualung Core Supreme Regulator - A-clamp is a lightweight regulator, perfect for British diving. The balanced diaphragm regulator is an Auto-Closure Device (ACD) with two HP ports and 4 MP ports.

    First stage

    The advanced first stage regulator is capable of delivering a 1st stage flow rate of 1450 l/min, and comes with an Environmental Dry Kit. The 1st stage weight of the DIN regulator is just 510 g, which makes it easy to carry, and relieves more than 200 g of load from the diver. The first stage regulator is chrome plated over marine brass for durability and longevity.

    Second stage

    A heat exchanger at the second stage end of the hose uses water temperature to warm the air as it rushes through the valve. This prevents exponential free flows and freezing valves, making it ideal for cold water diving.The pneumatically balanced second stage is controlled with a Venturi switch, and comes preset with breathing resistance. Along with the well-designed regulators, the mouthpieces are ergonomically designed (Comfobite), and come with a Lip shield and standard bite wings in the box.

    • No matter the depth, balanced first and second stages deliver consistent amount of air.
    • The Core supreme is an Auto Closure Device (ACD) which keeps corrosive water out of the first stage inlet by automatically closing as the CORE is removed from the cylinder valveThis prevents internal lubrication from washing away
    • Safer for elevated percentages of oxygen
    • Superior, consistent performance with balanced diaphragm first stage
    • Smooth, easy breathing with pneumatically-balanced second stage results in
    • The Venturi Adjustment lets you adjust the flow during the dive, while interrupting a free flowing second stage by redirecting the airflow towards the diaphragm.
    • Uses parts that are common to other Aqua Lung models for easier servicing
    • Compatible with EAN 40 new, out of the box
    • Equipped with Aqua Lung’s patented Comfo-bite™ mouthpiece along with a reusable mouthpiece clamp
