In one word, Amazing!
In one sentence, the Preval Sprayer is a professional grade spray system that is for countless applications, disposable, recyclable, easy to clean and where no compressor is needed.
How Preval Sprayer operates is simple, efficient and compelling. Because of the Sprayers patented venturri vaccum process, liquid or paint product is pulled from a removable, refillable Product Container. The pressure comes from the top part called the “Power Unit”, contained seperately from the “Product Container”. A dip tube runs through the Power Unit and into the Product Container pulling up whatever you are spraying.
When it all started was during World War II, when the first aerosol package arose to atomize droplets of liquid filled insecticide to protect servicemen from maleria. A few years later, Robert Aplanap, founder of the Precision Valve invented and mass produced aerosol valves and dedicated his career to being a world leader in smart, innovative and efficient valve technology.
