Lifejacket Inflation Systems Explained

UML Mk5 Inflator 

This is a water sensitive activation system that uses a compressed paper capsule which dissolves when wet which then releases a spring to puncture the CO2 cylinder.

The cap is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation.

UML Pro Sensor Inflator 

This is a water sensitive activation system that uses a compressed paper capsule which dissolves when wet which then releases a spring to puncture the CO2 cylinder.

The cap is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation.

The Pro Sensor has two indicators that show the status of the CO2 cylinder and firing head.

The UML Pro Sensor is a very reliable system which is easy to check and re-arm. It is also easy to convert to manual firing only. Re-arming kits for this inflation system are stocked by most marine stores.

3 year expiry date on firing head.

Hammar Hydrostatic Inflator

The Hammar inflation system is activated by water pressure and will not inflate until the cap is approximately 10cm underwater. 

This system is designed for use in more extreme conditions and extended offshore sailing.

The benefit of the Hammar system is that the jacket cannot accidently inflate from being wet with rain and sea spray.

The unit has a single indicator to show if armed, and has a 5 year expiry date.

Delayed inflation can be caused if full immersion of the firing head is delayed by buoyant foul weather clothing.

USCG APPROVED

Halkey Roberts Alpha Auto Inflator

The USCG Approved Deckvest LITE uses a water activated Halkey Roberts Alpha Auto Inflator that is is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation.
