Professional diving helmet 29019D

The superior DESCO 29019D Mark V Diving Helmet has been designed with the highest quality workmanship and materials for Navy divers. This is the late model standard U.S. Navy Helium/Oxygen Mixed Gas Helmet based on the standard Mark V Helmet. The main feature of this deep sea diving helmet is the canister mounted on the rear of the helmet and a venturi system allowing for recirculation of breathing gas to conserve Helium. The canister was filled with a scrubbing agent to remove Carbon Dioxide from the breathing mix. The breastplate is the same as a normal Mark V Navy Diving Helmet except the lock assembly is relocated to the front. All other parts are the same as a standard Mark V except for the omission of the spitcock valve, some additional ducting, and a extra communications elbow which the Navy used to connect electrically heated underwear to a power source. The canister can be removed and with the canister elbows capped the helmet can function as a normal Mark V Diving Helmet. Mark V Helium Diving Helmet for Navy Divers Original single exhaust Helium helmets did not have a lifting eye (as shown in the photos). We offer the lifting eye as an option on both styles of USN Helium Helmets. Standard finish is tin plate but the helmet is also available polished ($250.00 additional for polished helmet). The shipping weight with the canister is approximately 93 lbs. The U.S. Navy Mark V Helium Diving Helmet is available in two versions. DESCO can produce either style of this helmet for you.
