6.3 Accumulations of air in the filter cup
Depending on the filter insert and the suction vacuum of the facility, the air
separated from the oil may be retained by the filter insert to a major or minor
degree.
An air cushion may form upstream of the filter sieve; this air cushion is visible
in the filter cup. The size of the air cushion depends on the flow rate and the
suction pressure in the filter, i.e. more air particles may be pulled through the
sieve at a great throughput compared to a slow flow rate (lower oil consump-
tion by burner). When a vacuum is generated during operation of the burner,
this causes the oil level to decrease in the filter cup outside of the filter sieve.
The inside of the filter sieve is completely filled with filtered oil so that mal-
functions cannot occur. The irregular pore structure of the standard sintered
plastic filter insert with a spatial effect causes excellent permeability of the air.
