The BPV-3000 mist coolant lubrication spray system is designed for CNC lathes, milling, drilling, and engraving machines. Featuring a 300mm fully sealed flexible hose, it bends freely without air leakage, delivering stable mist cooling and lubrication. Equipped with precision valves for air (8mm) and liquid (4mm), users can easily adjust mist output for different machining needs. The 2.12mm copper nozzle and aluminum base with anti-corrosion treatment ensure durability. A built-in check valve prevents liquid backflow, while the copper filter removes impurities to avoid clogging. With a strong magnetic base, it can be installed and repositioned quickly. Compatible with water, alcohol, coolant, machine oil, and cutting fluid, this system helps reduce tool wear, save coolant, and improve machining efficiency.
