Valued Customer,


Voluntary Recall: Calypso Regulator with specific CPNs and serial numbers

Aqualung is conducting a voluntary recall of some clearly identified batches of Calypso regulators on both Din & Yoke versions, that may have a quality defect due to a variation in the manufacturing process of the first stage body. Only some Calypso regulators with a specific CPNs and serial numbers as mentioned hereafter are concerned with this recall. Thanks to our quality system, we identified this variation and decided immediately to make this recall on the concerned inventories. As of today, the number of regulators potentially impacted is less than 300 units.

Potential issue:

A hole has been drilled out of specification in the high-pressure port, leaving a wall thickness in a vulnerable state. An uncontrollable free flow of the second stage could occur if this thin wall section should rupture whilst under pressure. A pressure test has proved that an affected body will not rupture during a dive, however, we cannot guarantee the evolution in the long term.

Instructions for consumers:

  • Consumers are advised to immediately stop using their Calypso regulators, only if the serial number they own is part of the recall and return to the dealer from which it was purchased, for a replacement free of charge.
  • Dealers/Distributors are advised to stop selling their Calypso regulators, only if the serial number they own is part of the recall and send back to the Aqua Lung Group asking for a replacement free of charge.
