Helmets & Masks

Interspiro supplies police forces, armed services and rescue services throughout the world with rapid response and compact diving equipment. The Interspiro or "AGA" full face mask is the most widely accepted mask of its type.

The INTERSPIRO diving philosophy is a system philosophy. All parts of the breathing circuit – from the full face mask all the way up to the last thread on the DP1 Surface Supply – are tightly integrated. The reason is simple and obvious, to obtain the highest possible safety level for professional divers. INTERSPIRO gear divers are not sport divers - they are the best-trained and most experienced underwater professionals.

Divex, part of the JFD group, are the world leaders in the supply of the most advanced diving equipment. JFD is headquartered in Scotland and has bases in Australia and South Africa. In 2013 the Shanghai Salvage Company completed a record dive to 313.5msw using their saturation diving system built by Divex Australia.


The AH5 is the lightweight successor to the Divex free-flow AH3 and AH4 helmets. It is designed to be used either fitted with its own neck-seal, or locked directly into a dry suit. Because it combines many of the advantages of both the traditional hard-hat helmet and the modern diving mask, the AH5 is recommended for tasks as diverse as heavy construction, mobile inspection and protracted dives in cold and polluted waters. With an increased over-pressure option plus extra weights the helmet can be used in nuclear reactor fuel ponds. If the suit should leak then the increased over-pressure results in air escaping out of the suit and not water leaking inwards. Although the AH5 is light, it is extremely strong. The monocoque head shell is made from hand-laid impact resistant glass fibre.
