5.4. Connecting the compressed air supply
The compressed air must be dry and oil-free.
According to ISO 8573-1:2010 the compressed air quality must at least meet: [7:4:4]
➔ Partikle size: <40µm
➔ Pressure dew point: <= +3°C
➔ Oil content: <=5mg/m³
5.4.1. Compressed air supply for the cleaning of the filter cartridges
The filter cartridges of the system are automatically cleaned. Cleaning is carried out pneumatically via a
built-in compressed air tank.
Without compressed air supply the filter cartridges will become dirty very quickly.
● The external compressed air supply must be assured with an approved compressed air hose.
For the connection to the device, the compressed air hose must be equipped with a quick
coupling for an insert sleeve DN 7.2.
The compressed air must be dry and oil-free.
● The operating pressure of the compressed air supply must be a minimum of 3 bars and
maximum of 4 bars.
In case of the pressure being too low, the compressed air tank does not reach
quickly enough the operating pressure for the following cleaning. There is a risk of
material damage when the pressure is too high.
● Connect the compressed air hose to the insert sleeve (see chapter 2.1).
