At Last! An Honest to Goodness 12 Volt Hookah Diving System! Announcing Model 12V160-3....Another in the long line of Air Line firsts!
Thomas Industries once again comes through for The Air Line by J Sink with a tough compact, single-head hookah dive compressor that goes beyond -- actually, way below -- diving just under the hull.
This tankless 12-volt hookah diving system is a 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.
Understanding the 12 Volt/DC tankless dive system, its limitations and proper usage as an air-breathing device under water.
The Air Line 12V160-3 tankless scuba system, 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 dive 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 by J Sink has elected to offer a hookah diving 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 over pressure 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:
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 Air Line's stealthy tankless 12 Volt hookah diving system. (This approach is so effective that The Air Line by J Sink should get half of the finds. But we will cede all pull-tabs)
