The Salema Technology ACU machine has an electric motor with operating control system that drives a special fan and thus moves air. The result is an air displacement/air flow from one side to the other side of the machine in which the airflow is led through a number of filters. This creates a negative pressure on one side and positive pressure on the other side in which the outflowing air is filtered.

Depending on the application, the Salema Technology ACU machine can be used as a negative pressure (underpressure) machine (NPU) or as a positive pressure (overpressure) machine (PPU). In most cases the Salema Technology air cleaning unit is positioned /connected as a NPU to an airtight compartment or other sealed space/workspace, also known as containment. But the device can also be used as a PPU in a HVAC or cleanroom application.
