The DSL A-2air IV airhat oval entry is an ultra light breathing helmet for works on surface in nitrogen filled rooms, other toxic and unbreathable environments, as well as works in tunnels under pressure. This breathing helmet ensures an excellent wearing comfort and is easy to maintain.

The DSL A-2air IV airhat oval entry has two breathing air systems which work independent from each other, one separate and manually adjustable freeflow system and one screen defog system..The airdistribution block can be fixed at the worker's belt or harness

A springloaded exhaust/overpressure valve keeps a constant overpressure of 5mB inside the helmet. This to prevent any return of poisoned gas and/or toxic particles.

The workers security is also ensured by a double sealing system: One facemask and one neoprene neckdam.

This minimizes the level of CO2 leftover down to 0.02%.

The neckring is equipped with an anti-panic closing/locking system.

Helmet is equipped with integrated communication system which consists of one microphone and two loudspeakers. It has a 2D bent screen, 4mm thick with a big angle of vision.

The helmet is adaptable to all head forms and sizes thanks to its oval entry and anatomic inside configuration.
