Kirby Morgan 47 Specifications

A__The Helmet Shell is hand laid up glass fiber reinforced thermal setting polyester (fiberglass) with carbon fiber reinforcement at key points for added durability. It is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor. Kirby Morgan has over 50 years experience in composite laminations.

B__Steady Flow Valve provides an additional flow of air into the helmet backup air source for ventilation and defogging.

C__Auxiliary Valve supplies backup breathing gas to the diver.

D__Gas Supply Non-Return Valve is Commercial Rated™ and prevents loss of gas pressure in the event of umbilical damage, preventing a "squeeze".

E__Quick Change Modular Communications are either bare wire posts or a waterproof connector. The communications module is easily removed from the helmet, making repair or replacement of communications parts quick and trouble free.

F__Positive -Lock™ Latch System This latching system, developed by Kirby Morgan in 1992, consists of two spring loaded, sealed Positive-Lock™ pull pins which are pulled forward to release the neck collar and neck dam locking system. Pulling only one pin will not release the neck collar. Both pins must be pulled forward and locked open to release the neck collar. Then, even when the latches are released, the O-ring sealed neck dam maintains a positive seal and will not allow the seal to be broken until the collar actually clears the diver's shoulders, thus preventing any flooding of the helmet.

G__Head Cushion The Head Cushion gives the helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.

H__Air Train diffuses the incoming breathing air/gas onto the face plate to defog the lens.

I__Silicone Oral Nasal Mask is made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.

J__Nose Block Device allows the diver to block the nose to equalize ears.

K__Rex® Demand Valve The Rex® Demand Valve (patents pending), with it's full adjustment balanced piston is a breakthrough design that exceeds all requirements of all government or other testing agencies. It has the best work-of-breathing performance when compared to ANY other commercial diving helmet. The Kirby Morgan 47 Dive Helmet has been tested and is certified to meet or exceed the requirements of all government or other testing agencies. This helmet has an entirely new breathing system, oral nasal mask, and water ejection system.

L__Externally Adjustable Chin Strap The externally adjustable chin support, along with the adjustable neck pad on the locking collar gives the diver a comfortable, secure fit. M__Adjustable Neck Pad The helmet attached yoke system has an adjustable neck pad which is made from a scuff resistant elastomer. In conjunction with the spring activated front neck dam ring lock, it provides protection for the bottom of the Helmet.
