Bobbin HR Alpha (New Type)

This water‑activated bobbin (salt tablet) is designed for automatic inflatable lifejackets equipped with the Halkey Roberts Alpha release mechanism. When the bobbin comes into contact with water, it activates the release system and inflates the lifejacket.

This updated HR bobbin provides improved performance and reliability, particularly in humid and damp environments. It is clearly marked with production date (month‑day‑year) and expiry date (month‑year) to support proper inspection and maintenance.

The shelf life does not exceed 5 years from the manufacture date. After removal from its original packaging, the recommended service life is 2 years. The product should always be stored in a cool, dry environment.

Compatible with lifejackets fitted with Halkey Roberts release mechanisms.
