With the MULTIPASS TEST, the filter element must
show that it’s properly capturing the contaminates as
promised: The separation efficiency and dirt holding
capacity are determined here.
The FLOW MEASUREMENT records important filter
characteristics which are measured by the pressure
increase in the volume flow.
At the PULSATION TEST, the housing and filter heads
are subjected to powerful pressure: This shows how
long the parts can withstand continuous pressure pulsations with low, medium and high pressure.
At the BURST PRESSURE TEST everything goes
to pieces – and that‘s exactly what needs to happen.
The filters must withstand extreme pressure. A burst
pressure test is conducted to make sure that the filter
will continue to last at pressures far greater than the
normal operating pressure. Otherwise, it goes back to
the development workshop.
The COLLAPSE PRESSURE TEST also tests for failure
of the filter as the fluid passes from the outside of filter to
the inside as a result of extreme differential pressure. They
must withstand a pre-defined differential pressure.
During the BUBBLE POINT TEST, the seal of the filter
elements is put to the test. Compressed air is intro
