Frequently asked Scubabreather questions

How long can I breathe underwater?
A diver could virtually stay underwater the entire day!  The diver will get a consistent unlimited supply of air.  
The unit is designed to run continuously with no time limit.  

How deep can I dive?
Model SB201A single regulator unit -  This dive unit will deliver air to 1 diver to 40 feet.
Model SB202A dual regulator unit    -  This dive unit will deliver air to 1 diver to 40 feet, or 2 divers to 25 feet.
Model SB203A triple regulator unit   -  This dive unit wil deliver air to 1 diver to 40 feet, or 2 divers to 25 feet, or 3 divers    to 10 feet. 

Will I taste oil from the compressor?
No.  The SCUBA Breather compressor is the heart of the unit and was carefully chosen for the job.  It is a medical/laboratory grade oil-less compressor.  Oil-less in this case means that breathing air does not come in contact with any lubricated part.  There are other "surface supplied diving" system which utilize compressors that are not "oil-less."
What happens in these cases, is a piston rapidly scraping against an oil lubricated surface will produce toxic gasses that are breathed by the diver; over time this will result in a serious health risk by damaging the lungs.  
Avoid any diving system that incorporates a gasoline engine to run a compressor, or any compressor that is not "oilless."

Will I get shocked if the unit falls into the water?
No.  The Scuba Breather’s electrical system is properly grounded and built to National Electrical Code standards. 
The unit weighs 57 lbs., and is very stable when sitting on a flat deck, and would take quite a bit of effort to drag into the water.  However, as indicated in the Operating Procedures of your SCUBA Breather, it is highly recommended that the unit be tied off to an immovable object before diving.  This will preclude any possibility of the unit being dragged into a pool. Also, for extra insurance, a Ground Fault Interrupter (GFI) circuit could be used, but is not necessary. A GFI will automatically shut off the power supply if the slightest electrical fault is sensed.  A plug in GFI is inexpensive and can be purchased from any hardware store and plugged right into your 120 Volt outlet.

If the unit does fall into the water, exit the water immediately, disconnect the power supply, then remove the unit from the water.  Dry off the unit by letting it sit directly in the hot sun for a day – IMPORTANT STEP - before starting the unit, remove the air filter element from its housing and discard, as starting the unit with the wet filter element may clog up the internals of the compressor.  Call us up, and we will rush another filter element out for replacement.  After performing these steps, the unit should be good to go after that. If the unit falls into salt water, call or write to Scuba Breather Inc. for advice on how to clean it before reuse. 

Will the Scuba Breather work with European voltages?
Yes, we manufacture a "European style" SCUBA Breather to match the voltage and frequency of the electrical service in Europe, Mexico, and South America.
Scuba Breather single regulator unit - Model SB201E will run on 220 Volts A/C at 50 Hz.
Scuba Breather dual regulator unit -    Model SB202E will run on 220 Volts A/C at 50 Hz.
Scuba Breather triple regulator unit -   Model SB203E will run on 220 Volts A/C at 50 Hz.
Specify your exact needs in an email to when ordering for Europe or any country that requires a different voltage and/or frequency - we will fit you up.

Can I inflate my raft with the Scuba Breather?
Absolutely.  Attach the appropriate fitting and hose onto the existing Quick Disconnect Coupling, and pump it up.  At 3.5 cubic feet of air per minute, it will be pumped up quick.

Can I pump water with the Scuba Breather?
Absolutely not.  The unit is designed to pump and compress only breathing air.

Will the unit get damaged if it gets rained on because the lid was inadvertently left open?
Probably not.  If the lid gets left open, and the unit got rained on all night long, just let the unit sit out in the hot sun for a good drying out before using it again.  You should be good to go after that.  We have drilled holes in the bottom of the Scuba Breather case so that water will drain out should it be left out in the rain.  

However, we want to be up-front and straight forward here.  Every precaution should be taken to assure that a precision instrument like the SCUBA Breather does NOT get rained on or dropped into the water - water damage is not covered under the warranty.

Will the Scuba Breather unit float?
No.  The units are not meant to be directly floated in water.  However, the entire unit can very safely be floated on a small raft.  There are MANY rafts on the market that would be perfect for the job.  See the question below "Why doesn't the SCUBA Breather have a tube type raft..."

What if someone shuts off the unit while I am diving?
First of all, having competent people in your boat who understand that a diver is in the water is imperative.  Once a problem is detected, as in ANY type of SCUBA diving, the diver should surface IMMEDIATELY to investigate the problem. If the unit stopped running, the diver will not experience an abrupt interruption in breathing air, this is where the function of the large 1021 cubic inch of reserve tank volume takes over.  Rather you would start to experience more labored breathing as the tank air was used up, giving you time to get back to the surface. 

Can the unit be used in salt water?
Yes.  The entire unit is made of high corrosion resistant materials (stainless steel and brass) that can take salt water or salt moisture.  

How long can I expect the unit to last?
For a lifetime!  This is the best part about the quality that was manufactured in to the Scuba Breather.  Because of the quality components and materials used in manufacturing the Scuba Breather, there is very little that can go wrong.  
This includes a complete compressor and regulator rebuild with all new wearing parts,  a pressure switch inspection and calibration, a new filter element, and a through cleaning.  The regulator can be overhauled by any competent dive shop.  However, none of this needs to be done if the unit is operating properly and performing well.

Since I do not need a certification to use the Scuba Breather, I will not need any training.
This is the last thing we would ever want to imply.  Diving with the SCUBA Breather is real underwater diving.  The forces that are working on divers with tanks, are the same forces that will be working on a diver using the Scuba Breather.  You need to come to understand these forces.  This is the reason a training manual is provided to you when you purchase a unit.  It is a must read!  
The first time you dive using the SCUBA Breather (or any diving equipment), take it slow, and get to know it well.  When you do, your enjoyment will be greatly enhanced.

Will I need to buy a buoyancy compensator? 
Probably not.  A buoyancy compensator is used in regular SCUBA (with tanks) to change the buoyancy of the diver as air in the tank is consumed.  As air in the tank is consumed, the diver will become more and more buoyant because the tank will start to weigh less.  This is the purpose of the buoyancy compensator.  With the SCUBA Breather there is no tank, thus this problem does not occur to begin with.  However, the buoyancy compensator does double as a life vest. Considering safety is never a bad idea.  A diver may need a weight belt  - these can be purchased from any Dive Shop.

I have a buoyancy compensator that is fitted with an automatic air fill button.  Can you hook this up to operate with the Scuba Breather system?
Absolutely!  Send your buoyancy out to us.  We will custom fit your buoyancy compensator with our system so that it operates exactly as it did with your SCUBA tank system.

Does the unit require any routine maintenance? 
The Air Filter element should be changed out every 2 seasons.  Also, every few weeks or 3 hours of use, drain condensate from the storage tank as needed.  Besides these items, there’s not much to do.  
The Scuba Breather units never needs oiling. 

Can I modify the unit for more performance?
No. The unit is already set up for maximum performance by our technicians.  Any modifications to the unit would probably result in lower performance.  Modifying the unit or tampering with the electrical controls will void your warranty.

If my SCUBA Breather performance starts to drop, what is the most likely cause? 
The Air Filter element.  Extra elements can be purchased through us.

Why doesn't SCUBA Breather have a "tube type raft" to float the equipment on like some other manufacturers do?
Because we know that it is simply not practical.  
The donut shaped blow-up tubes that some other manufacturers use are really only practical in very calm waters like lakes or inter-coastal waterways.  Ten minutes in the ocean and the unit is doomed to capsize because of a wave.  This would abruptly leave the diver with a shut off breathing air situation.  Even when using these units in an inter-costal waterway, the unit will capsize when hit with the first boat wake!
Our Engineers believe that the only practical way to dive in the ocean, or any waterway where there is the possibility of another boat's wake, is from a boat - this is unquestionably the safest way to go!  With our design, all of the equipment is safely inside a boat (or a good size raft), where there is absolutely no chance of waves splashing water onto the equipment and into the intake of the unit, or worse yet, for the entire unit to be turned upside down because of a wave.
In calmer waters like lakes, we leave it up to the user of our equipment to purchase a small inexpensive raft, preferably one with a rigid floor - and there are many on the market.  Once you give this a thought, you will come to see our reasoning.  Your safety is truly very important to us!

Will I feel a pulsing air sensation as I'm breathing?
No, the Scuba Breather's storage air tanks also acts to dampen out any pulsing sensation.

Is there danger a breathing in Carbon Monoxide?
No, not with the Scuba Breather.  Our unit is powered by electricity, NOT by a gasoline or diesel engine. There may be units on the market that run on this principle - they should be avoided at all costs!  On these units, the engine exhaust is just feet away from the intake of the compressor.  There have been many recorded accidents with floating scuba units that are powered by small gas engines - don't become a statistic!  

What if I want to power up the Scuba Breather with a small gasoline powered generator?
This is an excellent way to operate the Scuba Breather.  Just make sure your generator exhaust is downwind or at least 10 feet away from the SCUBA Breather; using an extension cord will help you accomplish this.  Even running a generator on a boat this should not be a problem - place your generator at one end of the boat (downwind side) and the SCUBA Breather at the other end.

How is shipping handled?
You unit will be shipped (usually UPS) 2 or 3 days after we receive the order.  Actual shipping usually takes 5 business days.  So you will usually receive your dive unit 7 to 10 business days after we receive the order.  We will neatly and safely package your Scuba Breather. Shipments may be in 1 or 2 boxes, and boxes may arrive at different times.  We will ship to anywhere in the world.  We have made shipments to:  Switzerland, Africa, Australia, Dubai, Saudi Arabia, and other countries.  Add an extra week for overseas shipments.  
If any equipment is damaged during shipping, contact up immediately. We will have the equipment picked up by the shipper and you will have a new unit manufactured and re-sent.

What if my SCUBA Breather does malfunction?
Ship it back to SCUBA Breather Inc..  If still under warranty (1 year), we will repair or replace the defective part, then we will ship it back to you at no cost.

How safe is the SCUBA Breather?
It is the safest tankless breathing system on the market.  
The first line of SCUBA Breathers were developed in 1994 and are still running and with no safety incidences!
Safety features:
- The unit runs delivering 100% filtered and oil free air.
- The compressor is a continuous duty piece and is practically indestructible.  Our compressor and electrical system
   has more compliance and worthiness ratings than any system on the market.
- If the unit was switched off, there would not be an abrupt interruption of air delivery, however the diver would 
  sense this and be able to surface before all air is exhausted from the storage tank.
- Because we are interested in your safety and want you to be a good diver, we include a dive manual with 
  every order.
- For those who have never used conventional SCUBA with tanks – anyone would admit it is quite a cumbersome 
  task, and is practically impossible for small children!  Most children who have tried the Scuba Breather caught 
  on to it immediately.

How long are the hoses?
Model SB201A - From the unit to the regulator is 52 feet of hose.
Model SB202A - From the unit to the regulator is 52 feet of hose. 
Model SB203A - From the unit to the regulator is 52 feet of hose.
Optional 100 foot hose is available for all units.  See "Dive units", for more detail.

How does the SCUBA Breather pressure control system work?
The SCUBA Breather uses an digital type ON-OFF electrical control circuit.  The compressor will pump up the tank and automatically shut off at a set pressure.  When air is used by the diver, the compressor will start automatically until the shut off set point is reached.  ON-OFF control circuits are the most common and most dependable circuits available.  Your home air conditioner, refrigerator, clothes dryer, and other large appliances work using ON-OFF control.  Our Engineers chose ON-OFF control for the SCUBA Breather because of its dependability.  
Variable control circuits frequently malfunction and require too much maintenance.
