EtherFill 5000 Cylinder Fill System
EtherFill 5000 Cylinder Fill System
To use the EtherFill 5000, connect the Ethernet cable on the EtherFill 5000 to any RJ45 Ethernet port on your computer or network hub. Then connect the fill whip on the EtherFill 5000 to your cylinder. Attest that you are certified to use the gas you are about to download. Then begin downloading your gas fills from the Internet directly into your cylinder, using the EtherFill 5000. Watch the gauge, and when your cylinder is full, just close the handwheel on the fill whip, or abort the download. Introduced on April 1st, Nitrox-ready, the EtherFill 5000 is rated up to 5000 psi service.
Caution: there are dangers involved in overfilling cylinders. The built-in flow restricter ensures that your fill rate never exceeds 500 psi per minute. Your actual fill rate is determined by the bandwidth of your Internet connection, not recommended for use over dialup. The EtherFill 5000 is supported only on the Microsoft Windows Vista operating system (we plan to skip straight to Windows 11 just as soon as we figure out how to center the app launch icon on the taskbar.) Linux will be supported just as soon as someone in the Open Source community will debug the drivers. We've contacted Apple about developing an iPhone version but Apple is fussing about allowing in-app purchases. We have an Android tablet version currently in beta test for those divers seeking extremely flat gas for sidemount. As soon as the Compressed Gas Association publishes standards for chrome plated gas, we will start work on a Chromebook interface.
The fill whip on the EtherFill 5000 is a flexible high-pressure 60-inch hose with stainless steel fittings. The fill whip includes a valve and a male DIN connector. If you need a yoke connection, just spin on a DIN-to-Yoke adapter (working pressures limited to 3442 psi with the yoke adapter).
The pressure gauge is a quality SPG calibrated to 5000-psi in 100-psi increments. Its solid brass and tempered glass housing features a Bourdon tube mechanism. The Bourdon tube design provides the greatest degree of accuracy and reliability -- especially when enclosed in a solid-metal case. The EtherFill 5000 is also available as a metric version reading in BAR.
The hybrid Li-Po-Ni-MH battery technology on the EtherFill 5000 is similar to that found in the Samsung Note 7 devices. These batteries are substantially smaller and lighter than all other batteries offering comparable heat output.
The red LED indicates the status of the network congestion management algorithm. The LED blinks to indicate the EtherFill 5000 is searching for any network devices. Once found, each network device will be automatically shutdown. Thus you may rest assured that you will never experience network congestion problems with the EtherFill 5000.
As always, after you complete your breathing gas download, you should analyze your cylinder contents with an Oxygen Analyzer because your download might have been corrupted. You can double check your cylinder pressure with the DIN Cylinder Pressure Check Gauge.
Coming Soon -- The EtherFill 5000 Plus will enable you to upload your leftover fills to Dropbox. You will be able to use your stored gas yourself at a later date, share it with your buddy, or trade it with other EtherFill 5000 Plus owners. For green rebreather divers concerned about CO2 emissions, the EtherFill 5000 Plus will allow you to upload CO2 from your scrubber and reduce your carbon footprint. Many have suggested we add a USB option and we are researching the feasibility of an O2 compatible USB cable allowing you to store gas on any 5000 psi rated thumb drive.

ADVISORY: Oxidane and Diving
Recently there have been discussions that some recreational SCUBA diving sites can potentially expose you to Oxidane, a chemical name recognized in 2005 by the International Union of Pure and Applied Chemistry (aka IUPAC). Oxidane is a colorless and odorless compound with solid, liquid and gas phases that was previously considered to be relatively non-toxic in its pure form. While Oxidane can occur naturally (it has been found in acid rain), Oxidane has now been shown under laboratory conditions to cause serious DNA damage via the release of purine nucleobases and the hydrolysis of amino groups, a process described by the National Institutes of Health (NIH) as depurination and deamination. Oxidane is becoming ever increasingly used in many industrial processes, but not always in a sustainable manner that avoids Oxidane contamination.
Oxidane has been observed to exhibit some of the following properties of specific concern for SCUBA divers:
- accelerates corrosion of some metals commonly used in SCUBA equipment.
- can damage or shorten the life of electronic equipment such as dive computers and Nitrox analyzers.
- in rare cases has been known to cause tissue damage (aka 'burns') to the skin of SCUBA divers.
- believed to be associated with some diving fatalities, according to recent research of Divers Alert Network (DAN) .
A study of laboratory rats has established the Oxidane median lethal dose (LD50) is 0.00009 mt/kg (scientific e-notation 9e-5) by oral ingestion. In rare cases of human fatalities, Oxidane toxemia with resulting hyponatremia has been certified by officials as the primary cause of death, although some cases also had an underlying comorbidity. In a recent legal action, a California jury awarded $16.5 million dollars to the family of a radiological worker who died in 2007 as a result of Oxidane intoxication a few hours after orally ingesting liquid Oxidane. (Concentrated isotopes of Oxidane are present in most nuclear power generating plants.) Regardless, the risks associated with Oxidane appear to be exaggerated as industry experts have testified that exposure in moderation to Oxidane is harmless or even essential for life.
Oxidane is relatively easy to detect at SCUBA diving sites and rapid result single-use test kits (using the CaCl2 method) are available at many home stores such as Lowes as well as on Amazon. Unfortunately, the California Office of Environmental Health Hazard Assessment (OEHHA) has not yet firmly established a 'No Significant Risk Level' (NSRL) for safe exposures to Oxidane. The Federal Food and Drug Administration (FDA) regulation of contamination levels in public drinking water (tap water) is also inappropriate for assessing most SCUBA diving sites.
Although controversial, SCUBA divers at sites with known Oxidane contamination may wish to consider at least using exposure protection to minimize contact and for lengthy extended range exposures using a full drysuit. Immunocompromised individuals might wish to avoid participating in recreational diving activities at sites with severe Oxidane contamination. The Oxidane Foundation website oxidane.org provides an informative FAQ titled 'About Oxidane'. However, Oxidane also has another uncommon generic chemical name - DHMO, with the independently funded dhmo.org website offering what might be considered an alarmist viewpoint on Oxidane.
As always, Dive Gear Express suggests SCUBA divers apply informed reasoning along with critical thinking when evaluating the information available. Just to be clear, none of the new or unused products from Dive Gear Express will expose you to Oxidane prior to initial use. Nitrox divers will be pleased to know that Oxidane is generally considered to be an oxygen compatible material, is not readily combustible and is not a source of ignition; although oxygen gas will absorb Oxidane in the form of water vapor.
