Specification: Material:plastic&metal&brass Size:30cm(L),hose about 1M. Fit for 8mm air pipe Cooling stone/metal/ceramic tile engraving machine. For CNC Lathe Milling Drill Machine. Features: 1) a lot of water problem solving tools, easier to clean up. 2) processing the coolant can save more than 80%, the cooling effect is no less than the conventional water-cooled. 3) gas processing chips are blown away, working safer. 4) the nebulizer gas and coolant is adjustable, easy to use on different processing conditions. 5) Even the super-hard alloy precision machining the workpiece can achieve a smooth surface 6) not only increases the machining cutting speed, save time and reduce processing costs and tool wear. NOTES: 1. Clean the liquid shall be used. 2. Do not use liquid-corrosive. 3. In the liquid without pressure output required to ensure that the air pressure in the range 5-7KGF / CM2 (atomization and gas, associated gas pressure). 4. Use the liquid viscosity at 68cSt or less. Package include: 1x Mist Coolant System
