DAA means the life jacket inflates automatically upon water contact, while also providing a manual pull-cord trigger.
This ensures maximum reliability in all scenarios — whether the user falls into the water unexpectedly or wants to activate the jacket proactively.
• Automatic inflation on water contact
• Manual activation as a backup
• Highly reliable dual-action system
DAAM functions essentially the same as DAA — the jacket offers two independent activation methods.
It triggers automatically when submerged or manually by pulling the handle.
• Combination of automatic and manual triggering
• Most universal choice for recreational and professional users
SAA indicates a life jacket designed primarily for automatic activation upon water contact.
A manual pull system may or may not be present, depending on the model.
• Simplest activation system
• No manual action required
• Reliable in calm conditions
• Not ideal for environments with heavy spray (may trigger prematurely)
UML (United Moulders Ltd.) is one of the most widely used inflator types.
It operates with a cellulose bobbin that dissolves on water contact, releasing the CO₂ mechanism.
• Reliable and cost-effective system
• Easy servicing and bobbin/cartridge replacement
• Suitable for most watersports
• Can trigger early in heavy spray or strong rainfall
• Requires periodic bobbin replacement
HAMMAR is the most advanced and spray-resistant activation system.
It inflates only when fully submerged — water pressure activates the mechanism, not rain, splash, or humidity.
• No unwanted activations from spray or waves
• Highest safety level in demanding marine environments
• Stable, highly reliable inflator for offshore use
