The oil indicator can be ordered as an accessory.
Either the oil indicator or a differential pressure gauge can be screwed onto the adapter.
An adapter
[1]
with the oil indicator can be screwed onto the filter head
[A]
to measure and evaluate the quality of
the compressed gas. For measurement, a partial flow
[C]
of the compressed gas flow at outlet
[B]
is routed through a
channel towards the testing tube
[5]
and then discharged into the environment.
The oil indicator has a built-in pressure reducer
[2]
which reduces the operating pressure required for measurement
down to 7.0 bar(g). For the measurement, the needle valve
[3]
must be fully open. Then a defined partial compressed gas
flow of 2- 3 l/min at 7.0 bar(g) passes through the testing tube
[5]
.
The oil contained in the compressed gas results in a progressively red discolouration of the testing tube from bottom to
top
[5]
. If the testing tube has completely changed its colour, it must be replaced. For further information, please refer to
the installation and operating instructions enclosed with the oil indicator.
