The Hammar H20 is a hydrostatic release unit that fits liferafts of all shapes and sizes.

Now the biggest selling hydrostatic release unit in the world. Its safe, reliable and simple design has earned it more world-wide approvals than any other unit.

Compared with conventional release units, the Hammar H20 offers savings of up to 50% over a 10 year period.

The white strong rope of Hammar H20 is secured to the deck or liferaft cradle and attached to the liferaft lashing with a sliphook. If the ship sinks, the water pressure will, within 4 metres, activate the sharp knife which cuts the white strong rope and the liferaft will float free. As the ship sinks, the liferaft painter line will be stretched and the liferaft starts to inflate. The Red Weak Link™ breaks and survivors can board the floating liferaft. The
Hammar H20 needs no annual service, maintenance or spare parts, but MUST BE REPLACED AFTER TWO YEARS.

Designed for liferafts from 6 up to 150 persons.
