Continuous Nitrox Blending System, 1.5 inch size, 13 cfm to 30 cfm (370 lpm to 850 lpm). The Stik homogenizes the input gases so thoroughly that they can be piped directly into normal compressors and pressurized. Nitrox with up to 40% oxygen content can be economically prepared with little danger of any mishap; over 40% O2 is NOT safely achievable with this system. The device is adaptable for production of various Nitrox mixtures, compressor flow ratings, and other physical variables. The blender consists of a tubular blending unit which homogenizes incoming air with pure oxygen that is fed into the Stik by a medical O2 regulator (CGA 540). A preset metering valve on the regulator governs the gas flow and prevents excessive O2 input. An oxygen sensor port is located near the outlet where an analyzer (not included) can be attached to monitor the O2 content of the Nitrox being delivered into the compressor. The compact unit is mounted on a varnished, wooden plaque measuring 26" L x 5.5" W x 7.5" D. The Stik also works well in conjunction with partial pressure mixing apparatuses. It can easily produce large volumes of Nitrox up to 40% oxygen content which is then banked in storage cylinders. When Nitrox of lesser O2 content is needed, the bank mixed is simply diluted with air at a dedicated mixing manifold station. This same banked Nitrox can be used to prepare Trimix in many cases. Thus, the Stik and Manifold prove to be a very versatile combination.
