The Drip-Pro™ Hi-Flo GEN 4 was created to meet the higher productivity demands of the spray dry industry today, not only to meet the demand for higher flow rates but to also meet the requirements of longer run times. The increased flow was achieved by changing two low cost interchangeable internal components allowing the user to keep the same body as previously used so Upgrading to the new Drip-Pro™ Hi-Flo Gen 4 is easy!
