Product Details

The Preval Power Unit is the sprayer mechanism of the Preval Spray Gun, a versatile spray applicator for all types of liquids. The Preval Power Units require the refillable container jar to function. Together, the Preval Spray Gun assembly will hold whatever fluid you choose and spray up to 16 oz. of liquid, depending on viscosity. The power units are disposable. When depleted replace with a new power unit. Many of those who use the Preval sprayer have multiple jars to hold different types of fluid like paint, adhesive, primer etc.

The Preval Spray Gun can spray epoxy, gel coat, solvents to clean gunk and grime and more. The Preval sprayer system allows you to keep multiple containers sealed and ready for your next job. This eliminates waste and makes cleanup quick and easy.
