Preval 368 Power Unit, 70 psi Pressure

The Preval sprayer is an aerosol-based spray system that allows the user to mix up any paint, chemical or solution and turn it in to sprayable material through Preval's patented venturi vacuum process. This process draws the medium from the attached reservoir and delivers a professional-grade finish on virtually any surface without mixing the propellant and medium together. This results in an unadulterated finish with no color change.
