    More and more people are diving with enriched air and this means\u00a0Padi Gas Blender course<\/strong>\u00a0and the demand for enriched air fills is also increase. However, there needs to be someone qualified to administer these fills to meet this demand. This is where the DSAT Gas Blender course comes in. It can result in one of two certifications: DSAT PADI Gas Blender Nitrox or DSAT PADI Trimix Blender.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

        Mixes pure oxygen directly into an empty and oxygen clean certified SCUBA tank, then topped off with with Oxygen Compatible Air (OCA) from banks to create desired oxygen mixture. Depending on the complexity of the blending station, you will spend a couple thousand dollars on the mixing panel and additional filtration system.

          • This Nitrox System uses semi permeable membranes to produce oxygen rich air (nitrox). The nitrox, at up to 40% oxygen, can then be compressed with an oil lubricated high-pressure compressor into scuba bottles or storage tanks for later use or with a low-pressure compressor for immediate delivery to divers.<\/span><\/p>

            The \u201cNew & Improved\u201d membrane system is up to 20% more efficient and easier to use. The system requires an air source to supply air to the membrane for separation. This air source (supply air) can be from high-pressure storage tanks or from a low-pressure compressor.<\/span><\/p>

            First, the supply air pressure must be reduced to 80-300 PSI for use in the membrane. A regulator is used to adjust the input pressure and volume of nitrox to be made. After the regulator the air travels through filtration to ensure a proper air quality that will not damage or plug the membrane fibres. After the filtration the air is heated to a stable temperature that is constant and optimal for the membrane permeation. This temperature is about 110 degrees F. After the heater the air enters the membrane.<\/span><\/p>

            The membrane is made up of thousands of hollow fibres. Oxygen permeates faster than nitrogen through these fibres. At the nitrogen outlet there is a fixed orifice that will allow the right amount of nitrogen to escape at maximum output to produce about 43% oxygen at the permeate outlet (oxygen rich gas). The permeate exits the membrane into a static mixing tube that allows ambient air to mix with permeate. The gas mixture is then analysed with an in-line sensor before delivery to the compressor for compression.<\/span><\/p>

            As the operator increases the input pressure on the regulator, the volume of nitrox produced is increased as well as the oxygen % of the total gas mix. Decreasing input pressure will lower the nitrox oxygen % mix.<\/span><\/p>

            This system requires a separate LOW PRESSURE COMPRESSOR or a LOW PRESSURE STORAGE TANK to operate the membrane<\/span><\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
