Lifejacket Inflation Options

Which Lifejacket Inflation Option Suits Your Needs?

There are three different inflation options available with inflatable lifejackets. The one suitable for you will depend on your needs and your intended use:

Manual Inflation

All Inflatable Lifejackets can be Manually inflated by the pulling the lanyard.

But choosing the manual option allows the wearer to swim without the lifejacket being activated automatically. This can be useful if you expect to wade when launching or tending to craft in calm waters.

Operation

1. Pull a lanyard.
2. CO2 canister is fired.
3. Jacket inflates.
4. Delivers full buoyancy in approximately 5 seconds.
5. Can also be inflated orally.

 

Standard Automatic Inflation

This inflation option is available on most Crewsaver Air Only Lifejackets and provides an alternative to the Hammar Mechanism. Inflation occurs automatically when the paper retaining collar dissolves on contact with water.

Operation

1. Firing capsule dissolves within 5 seconds of entry into water.
2. Firing mechanism pierces CO2 canister, inflating the Lifejacket.
3. Can also be inflated manually by pulling the lanyard or orally.

 

Hammer Automatic Inflation

The Hammar Inflator gives excellent protection from random activation caused by moisture, rain or wave splash. This is achieved by protecting the water sensitive element with a hydrostatic valve, which operates when submerged in over 10cm of water and, depending upon the Lifejacket style, held there for between 2 to 3 seconds.

Operation

1. Hammar works on water pressure, only operating when submerged in 10cm of salt or fresh water.
2. No accidental inflation, even in extreme conditions.
3. Cylinder is mounted on the inside of the Lifejacket inflation chamber.
4. Re-arming instructions and key provided with each Re-arming Pack.
5. Can also be inflated as manual version or orally.
