An Inflator is always needed when diving if compressed air or other gases should fill up your items of equipment. For example, this can be a dry suit or a buoyancy compensation jacket. Thereby the air pumped in confers additional buoyancy to the items. Thus a rescue can be accelerated for example.
How does an inflator work?
It is composed of a tube as well as two valves. One of them is connected to the compressed air cylinder and the other one to the equipment item that needs to be filled up with air. If the valve on the cylinder is opened, you can fill up your jacket at discretion with a special button.
