1.1 Design and Function
Exhaust Filters
In the exhaust filters oil mist and aerosols are trapped,
whereas easily volatile substances and aromatics pass
through the filter.
The gas discharged by the vacuum pump flows through
the filter element where smallest oil drops and dirt parti-
cels contained in the gas are trapped. The separated oil
drops are collected in the exhaust filter.
In the exhaust filter AF 40-65 two filter elements are
arranged in parallel.
Filter elements may get clogged in the long run due to
crack products in the oil, and this may cause overpres-
sure to build up in the pump. In order to make sure that
the pressure will not exceed an admissible value
(approx. 1.5 bar) a pressure relief valve is provided on
the exhaust filter.
If the filterelement should have become clogged,the buil-
tin pressure relief valve opens so that the oil mist expel-
led by the pump is conducted into the open air. In this
way any damage which might be caused by overpressu-
re is safely excluded.
An exhaust line fulfilling the safety require-
ments concerned is imperative if poisonous
gases or vapours are filtered.
Observe the applicable safety regulations
for the media which are pumped.
Condensate Traps
Condensate traps mounted into the intake line protect
the pump from condensates which might result from the
pumped vapors and gases.
Condensate traps mounted into the exhaust line protect
against backflow of liquids which might condense in the
outlet line.
Condensate traps can be fitted optionally on the intake
and/or exhaust side of a TRIVAC pump.
