The Faber 300 bar, 5 litre (53 cubic foot), 140 mm (5.5 inch) diameter, Steel Cylinder with High Pressure DIN valve and cylinder boot is Nitrox ready. These cylinders are made by Faber, the leading European manufacturer of scuba diving tanks, with extremely high quality steel made to international standards. Faber cylinders display a unique combination of size, weight and buoyancy. Please Note: Oxygen Clean can only be completed on cylinders being picked-up in store. The valves are made by San-o-Sub, a leading Italian manufacturer of medical, industrial and scuba valves. They are strong and reliable and are made from really top quality materials. The inner air passages were carefully studied in the design so as to guarantee top performance even, and above all, with the top performance regulators. The valve design ensures an excellent grip, facilitating opening and closing of the tank. Note: If you require your cylinder unvalved, instead of with a HP DIN valve, please specify when you order. Valve Oxygen Cleaning: The Faber 300 bar steel cylinders are supplied Oxygen (O2) clean, suitable for use with up to 100% oxygen. However, if you are planning to use the cylinder with Enriched Air Nitrox (Nitrox) mixes up to 100% oxygen, it's essential for the safety of the cylinder user and the person filling the cylinder that the valve be oxygen cleaned and prepared with special o-rings, seats, and grease designed for exposure to pure oxygen. The cylinder should then be banded with the familiar yellow and green Nitrox band/wrap/sticker, and an Oxygen Clean 'In Test' inspection sticker applied. The Scuba Doctor can do all of this for you as an add-on service. Faber 5 litre, 300 bar steel cylinders from The Scuba Doctor are supplied with a self-draining flexible PVC cylinder boot to fit the round bottomed Faber tanks already installed. This protects the bottom of your cylinder and provides a streamlined profile for tank racks or doubling tanks.
