kennametal sn159 xl12 50mm super venturi nozzleThe SN159 XL12 50 mm Series is an XL Performance super venturi nozzle with a robust construction. The extended super venturi design increases abrasive particle velocity, enabling higher production rates than standard venturi nozzles of the same bore size. Air requirements remain comparable, allowing increased productivity without additional air consumption or compressor upgrades. The BP200 SiAlON liner provides high wear resistance compared to silicon
