The inflator is connected to the BCD / diving bottle with an inflator hose. With the inflator you can pump air into the trim vest and let it flow out again. Via a mouthpiece that sits on the inflator, air can also be blown into the jacket by mouth.
The inflator therefore supports the BCD in creating a neutral buoyancy. If a situation arises in which air must escape quickly from the jacket, this can be done by pulling on the inflator with a string or pressing the vent button.
An inflator also needs maintenance just like a regulator to make it work properly.
An inflator service is available from € 15.00 (regular inflator) & € 25.00 for an Airtrim!
