Sectional view of the room air cleaner
A fan is installed inside the room air cleaner. When the room air cleaner is
switched on, the built-in fan is switched on. The fan creates a negative pressure,
whereby the room air is sucked through the intake openings into the interior of the
room air cleaner.
After entering the room air cleaner, the air flows through the fan and then through
the filter elements of the first and second filter stage. After passing through the filter
elements, the cleaned air exits the room air cleaner at the top.
4.2 Fan
The fan generates the negative pressure required for the air volume flow. The
speed of the fan can be adjusted by a potentiometer. The potentiometer is located
on the front of the room air cleaner, directly next to the on/off switch.

By changing the speed of the fan, the air volume flow and the negative pressure
are influenced. This allows the extracted air volume flow and the number of air cir-
culations per hour to be adapted to the size of the room.
