Specific remarks
P filter
The P grade filter can be used in installations where high oil or dust loads are expected.
In critical applications it is recommended to install a grade G (for oil) or a grade S (for dust) or a
grade C (for oil) or a grade D (for dust) filter downstream the P filter to improve the air quality.
G filter
No specific remarks.
C filter
The filter must be mounted as close as possible to the point of use of the air
It is recommended to install a grade G filter upstream the C filter. If not, the load on the C filter
element may become too high and will reduce its lifetime.
