The Purafil Positive Pressurization Unit (PPU) is a self-contained, air cleaning system, designed to provide pressurization air, free of corrosive gases. The PPU is recommended for controlled environments containing sensitive computer electronics and electrical equipment. Designed to stand alone, it can also be used in conjunction with Purafil’s Corrosive-Air System when recirculation is also required. Key application areas for the PPU are computer rooms, control rooms, motor control centers, and electrical equipment rooms in industrial environments, such as pulp and paper mills, petrochemical plants, refineries, steel mills, laboratories, and other process industries.
