The AH5 is the latest free-flow air helmet from Divex to be regarded as setting the standard for safety, quality, performance and reliability by commercial divers themselves.
The successor to the Divex AH3 and AH4, the Divex AH5 is a lightweight, free-flow air helmet designed to be used either fitted with its own neck seal, or locked directly into a drysuit.
Combining many of the advantages of both the traditional hard-hat helmet and of modern diving masks, the AH5 is recommended for tasks as diverse as heavy construction, mobile inspection, protracted diving in cold and polluted waters and nuclear diving.
Further Information
The free-flow air helmet maintenance course has been designed to provide candidates with the skills and knowledge required to correctly operate, maintain and service the AH5 and AH3 helmets.
Course duration: 1 day
