Mouthpieces-DSV (Dive/Surface Valves) for rebreathers

We  make several different mouthpieces - DSV's for most rebreathers :

Our Rotary style, with a easy turning  twist style valve with large handle.
All our mouthpieces are O'ring sealed with viton or Silicone O'rings
and are much easier to operate than most closed circuit DSVs (mouthpieces).
We have been building the same DSV mouthpiece with different connections
for several years, and find the closed circuit mouthpiece with the built in
bail to be the best backup system available.

We have several units on Inspirations, Draeger, and numerous other
rebreathers right now with great results.

Bubble Deflector For Drager Atlantis or Dolphin S.C. rebreathers

The Deflector mounts on the top of the shell  covering the over pressure
valve. It allow the bubble coming out of the over pressure valve to be
deflected into smaller bubbles and quiets the noise down from the
bubbles  coming from the O/P valve.

The Deflector mounts on the top of the shell with 2 s.s. screws, 2 holes must
be drilled into the shell for the inserts that the screws mount to.

The O/P must be adjusted with the deflector off.

We recommend that a PPO2 monitor be used with the Deflector to make sure
it is not impeding gas flow.

The cost of the Draeger Bubble Deflector is $US 125.00

Full Face Masks and Conversion Kits

Widolf Full Face Masks


The Widolf mask is the most versatile full-face mask being made today.
The face seal, head band and face plate remain the same on each mask, this modular construction technique allows the mask to be tailored for any job requirement.
Specialized valving and communications components are available to meet the needs of any diving job.
Unmatched comfort and fitability in a full face diving mask, can be worn for extended periods of time with less fatigue then standard scuba or other full face masks.
Foam reflex seal , protected by a film of neoprene rubber allows a comfortable fit for most faces.
Low profile/ low volume, neutrally buoyant, allows the Widolf mask to be easy swimming, especially in currents and rough water.
Five strap headband with quick release buckles, pulls evenly on the back of the head properly supporting the mask easing jaw fatigue problems.
Rugged, the most rugged lightweight full-face mask made.
Tempered glass lens, minimizes scratches and fogging.
Low maintenance High quality materials especially chosen for resistance to the effects of the marine environment, a rinse in fresh water is usually all the maintenance that's needed. other than periodic inspection of the valving.

The combination of the foam reflex seal and the adjustable five-strap headband ensures a perfect fit for most faces , and provides comfort for long dives,a feature which is missing in other masks.
The face seal is formed by a main neoprene body which is molded so that a flap folds back over a foam insert.
The interior space has an extremely low volume preventing Co2 build up.

Two types of nose clips are available. One pinches the nostrils closed, the other presses up to block the nostrils. Both can be easily installed on any Widolf mask. They are operated from the exterior of the mask and are adjustable for position.

Widolf Diving Equipment maintains a complete replacement inventory for quick shipment.

Widolf masks stay with the diver, even in severe currents. But if need be the diver can abandon his mask and "bailout" by forcibly pulling it forward and sliding it off his face

The inlet fitting on demand masks is a scuba 9/16-18 o'ring fitting.
Scuba Whip - Standard first stage hookup is for connecting a first-stage regulator to a Widolf demand free flow mask.
Emergency Breathing System hose is for connecting bailout bottles to a Widolf mask.

Full face coverage has many advantages over the conventional scuba equipment for the diver who wants the ultimate in diving safety and comfort.
Comfort is a big factor ,water leakage around the mouthpiece is eliminated, a problem which is not just a matter of comfort in contaminated water. And finally, a full face mask stays on the diver's face and continues to function, even if the diver is unconscious. The is no loose mouthpiece to slip from the diver's bite.

Available with or Without Communications,
Widolf Masks are designed to function with any type of communications, hard wire, thru water, or specialized communications,all types are easily integrated into the mask .All Masks are available with complete hardware or thru water communications.
The mask will accept most comms  OTS,Orcatron,Divecom, and Others  are all available  except possibly Divelink because of the headband.
An adapter is avalable ,that would allow you to  use the AGA style comms on the Widolf Full Face Mask.

The DF-500 Widolf Full Face Mask / Demand/ free flow:

Ideal for scuba ,surface supplied or search and rescue.
DF-500 Demand free flow masks have all the advantages of both types of breathing methods in a single mask. They function equally well with self-contained bottles or with hose-supplied air or gas. The diver can breathe solely on demand, or by progressively opening the free flow valve can breathe in different combinations of demand and free flow until the free flow overpowers the demand action. A control knob allows the diver to adjust the demand mechanism to a wide range of hose pressures to insure easy breathing.

The price is $US 945.00


The Widolf recirculating masks are designed for use with closed circuit rebreathers, semi-closed circuit breathing systems, or standard 2 hose regulators.

Backpack hoses are attached to the shutoff block at the front of the mask .
The shutoff block isolates the mouthpiece are from the backpack to prevent water from going into the closed circuit backpack.
Switches between closed circuit and open circuit demand mode in the DR series.

Allows the diver to select mode depending on there requirements.
CO2 buildup is kept to an absolute minimum by a close-fitting oral-nasal seal.
The directional flow check valves, have a very low resistance and perform very ,well with various closed circuit packs.

The flow direction can be changed to either direction. The standard direction of gas flow is from the diver's right to
the diver's left.

The Widolf DR-600 comes with our  Rotary style DSV Closed circuit/Open circuit
mouthpiece, with a easy turning twist style valve.

Available with several different sizes and connections.

The  price for the mask   is $US 1950.00
plus $US 50.00 extra for threaded ends or special ends (i.e.. for Inspiration or Draeger or others)

We have been building the same mouthpiece (DSV) with different connections for several years, and find the closed circuit mouthpiece with the built in bailout to
be the best backup system available. Just by rotating one lever you switch from your rebreather to open circuit.

Normal delivery is 6 to 9 weeks
