I have a Spectrum brand air blast sprayer that still works great. This model is the old version of what is now called Electro Blast and mad e by the same company. The electro static feature does not work on it anymore but sprayer works fine with out it. This tis the 400 gallon with stainless tank.These sprayers have duck bill type nozzles so they do not plug up as easy as other sprayers. I am going a different route now and dont need this sprayer anymore. I have an extra belt and electric silenoid valve as a backup. This needs about 60h.p at the pto to run it. Some of the clear poly hose to the nozzles need replaced and maybe the other main feed hoses could use replaced also. Please call or text. Thanks
