4.4.1
General comments and use
Filters of the series AF (or optional series HAF) are suitable for filtering solids out of
compressed air and other neutral, compressed gases. This new filtration concept is
characterized by high flows at low differential pressure.
4.4.2 Function
The soiled medium flows through the filter element, series AF (or optional series
HAF), from the outside to the inside. Solids are filtered out by impact or by the effect
of inertia.
4.4.3 Assembly and installation
Advice

The piping system must be cleaned before assembling filter.

The filter must always be installed vertically.
4.4.4 Maintenance
Advice

The filter element should be replaced when a differential pressure of
> 5-7 PSID has been reached or, at latest, after 6 months of operation.
4.4.5 Changing of afterfilter elements
Danger!
The soiled filter elements are changed only when the
housings are DEPRESSURIZED!
Advice

Filter elements should NOT be cleaned with compressed air.
