<p><strong>Introducing the world's most advanced venturi mixers that are virtually maintenance free, highly accurate, and provide easy and fast adjustment. Groz mixers use a rotary disc valve which is precision CNC machined from stainless steel. Other venturi coolant mixers are designed with either a needle valve or set of mixing jets. These designs can be time consuming to adjust, have too many parts, and/or are prone to blockage. The Groz Plus Coolant Mixer's rotary disc valve is highly accurate, and their compact construction and minimal parts make these coolant mixers easy to install and highly reliable.</strong></p> <p>NOTES:</p> <ul> <li>Groz has made specific modifications on these mixers for Coolant Consultants, lengthening and switching the suction pipe from plastic to threaded stainless steel</li> <li>Mixing percentage achieved can be dependent on incoming water pressure</li> <li>3/4" female garden hose brass swivel adapter included</li> </ul>
