This Overspray product is also similar to the 3000 Series, but has an added polyester backing which increases the overall efficiency needed for very finely atomized overspray particles. Producing excellent efficiencies, the 3200 Series results in a 50% reduction of overspray up the stack, and the poly backing makes it ideal for coating at any rate of production. It is available in pad or roll form and its recommended use is two in tandem.
