Questions and Answers for Air Line 12 Volt System Hookah:

  • David:

    Is this about a 2 hour dive for one person? If using the battery alone?

    Greg  (Certified Scuba Instructor at

    Yes, the Airline 12 volt Hookah system will support one diver for 2 hours.

  • Ron:

    I dont quite understand why a dive can only last 2 hours. What limits the dive to this amount of time? If I used an electrical supply from a sail boat that has rechargable batteries can the 2 hours be extented to several hours? My need for a Hookah is for bottom cleaning a 44 ft sailboat. The keel is 7 from the water line so depth is not a problem but time is if I can only depend on this model 2 hours at a time.

    Bill  (Certified Scuba Instructor at

    The time is based on using a single battery, of course if you have a continous power supply it will be as long as you want.

    Bob  (Certified Scuba Instructor at

    The 2 hour dive time is the average amount of time it takes this unit to drain a basic car-type 12 volt battery to the point it doesn't have enough charge to operate the unit. Additional power sources would extend the dive time, but also keep in mind this is a recreational unit and not a commercial unit and is not designed for extended use or even potentially daily use over and extended period of time.

  • John:

    Can you deliver to UK. If so please advise cost and delivery period. Thanks

    Bill  (Certified Scuba Instructor at

    You can place the order on the website. Using Amazon Checkout is the easiest way to process international orders. The shipping will be listed when you proceed to checkout and prior to submitting the order.

  • Ronny:

    how deep can i go with this system?

    Bill  (Certified Scuba Instructor at

    Supports one diver to 50 feet for up to 2 hours.

  • Darren:

    This is my idea, please let me know if you think it will work: If I ran a small 1000w silent generator on the deck of my pontoon boat and clipped the positive and negative to the terminals on the gen will it work correctly?

    Arthur  (Certified Scuba Instructor at

    I wouldn''t try it.

  • Mike:

    Has anyone measured the Decible level of the compressor when it is running under load?

    Kevin  (Certified Scuba Instructor at

    We are not able to determine that information at this time. Please contact the manufacturer for more details regarding this item.

  • Ryan:

    Can this unit be changed to operate on 110 outlet?

    Bob  (Certified Scuba Instructor at


  • Mark:

    Do you have a container and float system foe this unit and a battery?

    Arthur  (Certified Scuba Instructor at

    this model is meant to be a dock or deck mounted unit.

Announcing Model 12V160-3. Another in the long line of Air Line firsts.
Thomas Industries once again comes through for The Air Line with a tough compact, single-head compressor that goes beyond -- actually, way below -- diving just under the hull.

Terrific option for sail boaters, power boaters who don't want to carry gas, and metal detectives who want to keep a low, quiet profile.

What better way to do those really fun projects like scraping barnacles, changing zincs, chopping line off the prop. No tank to bop the gel coat, no yo-yoing up and down til your lungs give out.

For you folks who like numbers:

Performance: 3.25 CFM @ 0PSI, 2.18 @ 50. One to depth of 50 feet. *See Foot Note
Motor: .1/3 HP DC. Rated Load: 26 AMPS.
Recommended Battery: Group 31 Marine. (Expect two hours of operation.) Group 27. (Expect one hour, 20 minutes.) One D-Cell. (Expect ridicule.) Running the boat engine will keep the battery charged.
CAUTION: Exhaust fumes from other resources are toxic. (outboards, generators etc.) Ensure that the intake air is uncontaminated. A low-cost, remote air intake hose can be ordered.

Weight: 23 lbs. Size: 12' by 8' by 6' high on white, rubber feet. (Allow 19' L for hose bend, cables and overpressure, Quiet Valve)

Mounting Notes: The compressor can be custom mounted in any position.

And what ABOUT those underwater metal detector guys. In public places they need to accomplish two things to get the prize: They need relative silence, and zero fume emissions. Enter the stealthy Air Line 12 Volt system. (This approach is so effective that The Air Line should get half of the finds. But we will cede all pull-tabs)

Understanding 12 Volt/DC, its limitations and proper usage as an air-breathing device under water.

The Air Line Model 12V160-3, just as it comes from the factory, is an excellent and efficient tool for providing breathing air in the situations for which it is intended: The sailor who needs to work on the hull when underway. The metal detector user searching for treasure (perceived, or otherwise) in the lake or river.

It's important, however, to understand that the performance of a 12Volt compressor is directly related to its AMP draw. AMP is loosely defined as being the strength of electric current. The higher the AMPS, the stronger the current, therefore the stronger the power. Breathing at any level, even at the surface, requires both pressure and volume.

The problem is that at some point, it is impractical to supply the strength to accomplish the job due to battery sizes. Battery banks on large boats, or keeping the motor running will accommodate the AMP power needed for larger compressors. Gas or 110Volt/AC powered units start off with considerable 'strength' and are, therefore, more able to overcome resistance within their given parameters.

Understanding the limitations of the 12V system will arm you with the knowledge to use it safely and efficiently.

As a preface, the Air Line has elected to offer a system based upon reasonable performance and the power needed to make it work within its limitations. Model 12V160-3 has a 'draw' of 26 AMPS. Fairly high, but not impractical (see the website for recommendations on battery size).

Under hard exertion, at even shallow depths, it is possible to 'breathe down' the compressor (consume air at a rate higher than the compressor can generate). The situation can be eased or prevented by slowing down (or even stopping) the activity and allowing the compressor to regenerate air into the hose, rest until breathing is normal, and then establish a pace at which there is no hesitation on the inhalation effort.

Follow these steps initially: Start the compressor, without load, by holding in the purge button on the regulator front (where the logo is). Hold for a few seconds to allow the air to travel from compressor to reg, to get a sense of the air flow. Release the purge and wait several seconds until the hose fills with air and the overpressure valve on the compressor is evacuating the generated air. If you depress the purge as though you are taking a breath, you will note that the air volume is considerably higher than at the start up. The reason for this is simply because you are breathing air from the hose, which acts like a reservoir, rather than directly from the compressor.

Labored breathing from heavy exertion means that the reservoir (hose) is being drained faster than it can supply.

The most positive fix, in preventing over breathing, is the incorporation of an accumulating tank at, or near, the compressor. The tank does not have to be large to be effective for a single diver under heavy exertion. The Accessories page on the website describes a 2-1/2 gallon, light-weight, stainless steel tank that perfectly fits the criteria of adding significant reservoir to the hose volume.

Initial testing was done without an accumulator and at a depth of 60 feet. The activity was very low. Moderate exertion caused labored breathing as the ambient pressure from the water was starting to counterbalance the pressure generated from the compressor. More realistic testing was done at a depth of 15 feet, again, without an accumulator, with a swimmer using a metal detector. Breathing was unlabored.

Thus fortified, with the information above, you can now fully utilize the Model 12V160-3 in all its quiet, fumeless glory.

Some smart options that you can view on the Accessories page:

Padded Gear Bag. (Protect and store)

2-1/5 Gallon Accumulator Tank (A must for two diver applications)

Addit 60' Diver package. (For adding a helper at keel-depth)

1. Q. What exactly is the concept of SSA?
A. Air from a low-pressure compressor at the surface pumps air through a hose and demand second stage regulator system directly to the divers below. Virtually no gear is worn and the divers have a lifeline to the surface with the hose system and a belt that secures the hose and regulator to the body. Top

2. Q. How long will the engines run?
A. Running time on the floating gas-powered models will be 3 hours on 2.5 qts gas. On the commercial XL2 model: 4 hrs on 0.95 gallon, regardless of the number of participants on either. Top

3. Q. Do the motors require an oil gas mix?
A. No. They are four-cycle engines and take unleaded gas with a pump octane rating of 86 or above. Top

4. Q. Are the compressors oil lubricated?
A. No. A Teflon cup on an aluminum piston pulsates inside the cylinder sleeve precluding the need for even rings and seals. Bearings are sealed and grease cannot enter the breathing system. Top

5. Q. What keeps exhaust fumes out of the breathing air?
A. Lawyers and the fear thereof. Mechanically, however, a vertical snorkel draws air in 30 inches above the compressor. Exhaust is shot away horizontally on the opposite side. The way the unit floats, the exhaust will always seek the down wind position. All Air Line system designs meet or exceed Compressed Gas Association Grade E breathing air standards. Top

6. Q. What depths can I reasonably expect on an Air Line?
The XL models will support two to a depth of 85', three to 60 feet, four to 40. The R-4 models will support two to 70 feet, three to 40. The systems are primarily designed for second atmosphere, recreational diving. (Be wary of claims. In our opinion, some manufacturers may exaggerate depth ratings for the air output of their systems. The Air Line chooses to be conservative, basing our depth ratings on people with average diving experience and in average physical condition. The depth capability of a compressor system will be determined by the air output of the compressor. Compare air output.) Top

7. Q. What length are the hoses?
A. They are all arbitrarily 60 feet because we have found this to be an optimal length for common hookah dive profiles. Hose extensions are available for lengthening hoses if desired. We will, however, customize lengths for certain applications such as deck mounting. It is important to understand that each diver has an independent 60 foot down line on an Air Line instead of a single down line. You will get more air volume under pressure in two, three or four hoses than you will through one; Common-Sense 101. There are safety factors involved also. We can discuss these through e-mail or a telephone call. Top

8. Q. Won't a salty environment cause the equipment to rust?
A. It would without a few simple care procedures. The gas-powered compressors are marinized and require no pre-dive procedures. The engines need a bit more attention. When new, thoroughly coat with a marine protectant, such as, Boeshield T-9. After the dive day, a fresh water bath will rinse away accumulated salt, followed by a light touch-up of the protectant. Top

9. Q. Is training needed?
A. Yes. Knowledge of the pertinent laws of physics is essential. Although easier to use as no gear is worn, you are still subject to the same physical laws that relate to scuba diving. BCDs are not discouraged but they are not as critical, as the weight of air in a scuba cylinder is not being consumed. Snorkel vests are an option but remember, you are connected to the surface float through the hose system. Top

10. Q. If the engine runs out of gas, what happens?
A. You are encouraged to come up. Silliness aside, you will be aware when the engine stops as each succeeding breath will require slightly more effort. The air in the hoses is under pressure and supplies a reservoir of air. As you may know, the air in the hoses will naturally increase in volume (i.e., expand) as you rise, so there will be a few more breaths in the hoses. However, The Air Line recommends that the divers carry an independent, back-up air supply (such as a Spare Aiir, see the Accessories section) whether diving on surface supplied air or scuba tanks. Top

11. Q. Are the floating models stable when the sea gets choppy?
A. Yes, but three or four footers are the suggested maximum. when you feel a surge on the hose you will know it's time to call it a day, or at least, go to the surface to evaluate the situation. Top

12. Q. Do the floats tow easily?
A. Yes. The divers being free of gear experience the freedom of snorkelers. Otherwise, the hoses being under pressure will arch gracefully down so the floats are not being pulled awkwardly. The task of towing is shared by at least two anyway. They should never be towed behind a boat except at slow idle. They will sink (no relation). Top

13.Q. How much separation can I expect on the Air Line's individual 60 foot hoses compared to a single down hose with individual 20 foot whips?

**The chart indicates what you can expect in separation and freedom, at depth, by using individual hoses. For instance: At 2nd atmosphere (33 feet) you would be able to explore up to 109 feet apart.

At any depth, on a system with only a single down hose, your separation would always be just 40 feet. ** Top

14. Q. Is there any advantage of having a single down hose?

It might look like a cleaner configuration for pictures, but is that what you're buying it for? (Excuse the answering a question with a question) (Also it's less expensive to provide only one hose.)


15. Q. What then, are the advantages to the Air Line's individual hoses?

A.1. Simple, common sense physics to start. You will have more breathable air volume in multiple hoses than in one hose.

A.2. The aforementioned separation (13.Q.), which equates to freedom (See, also, next answer).

A.3. Imagine being at a depth of say 60 feet around some coral, wreck or rock formations. With the floating, individual hoses you can easily maneuver about unobstructed. On the one down hose at 60 feet, the 20 foot whips will be effectively horizontal, restricting movement to follow-the-leader.

A.4. Let's talk SAFETY! At 60 feet on individual hoses, if one diver needs to reach the surface for any reason, he/she can calmly do so, hand-over-hand to the security of the float or boat. On the single hose, the stressed diver can only ascend 40 feet, the total of the two 20 foot whips. At that point he/she would have to jettison the towing belt, with the regulator, and swim the remaining 20 feet to the surface.

A.5. More on SAFETY. In the event of equipment failure, there will be a small reserve of air trapped in the hoses. There will be more air volume stored under pressure in multiple individual diver hoses than in a single down hose. On the single down hose, all divers must share the air from the one hose. (Note: The Air Line recommends carrying an independent backup air supply, like Spare Air, for all divers, whether on hookah or scuba equipment.)
