Positive Pressurization Unit

Positive Pressurization Unit (PPU)

The PPU is self-contained, air scrubbing systems designed to provide pressurized and/or recirculated air, free of corrosive gases. It is ideal for removing air contaminants from controlled environments containing sensitive computer electronics and electrical equipment.


  • Vertical or horizontal air flow
  • Robust design with small footprint Plenum with dampers to introduce outside air
  • Recirculation to maintain continued positive pressure
  • Speed control
