0 Important Safety Information
0.1 Hazards caused by materials and substances
1 Hazardous substances may escape from the filter, condensate or the
oil. Take suitable precautions (e. g. gloves, goggles or gas mask).
Observe all safety regulations.
2 When toxic gases or vapors are pumped, an exhaust line must be
fitted in accordance with the safety regulations relating to protection
against poisonous vapors.
3 Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts are
contaminated.
Adhere to the relevant regulations and take the necessary precautions
when handling contaminated parts; For example wear gloves, face
protection or breathing protection.
If there exists a potential hazard, the filter or the separator must be
decontaminated before starting with any maintenance work.
The filter pot may be as hot as 90 °C.
There is the danger of receiving burns.
Wear suitable protective clothing.
For professional decontamination we recommend our service.
4 The equipment must be packed in such a way, that it will not be dam-
aged during shipping and so that any contaminants are not released
from the package.
5 When disposing of used oil and spent filter and filter elements, please
observe the relevant environmental protection regulations.
6 The ARS can be operated with perfluoropolyether (PFPE) as lubricant.
When handling PFPE you should observe the following:
During thermal decomposition at temperatures over 290 °C toxic and
corrosive gases are released. When handling PFPE keep it away from
open fires. Do not smoke with PFPE on your fingers.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
do the necessary work in clean and dry rooms;
after having removed the pump from its packaging, start it up as
quickly as possible;
as cleaning agents solvents based on hydrofluorether compounds may
be used..
0.2 Risk of damaging the device
1 The filter element should be changed regularly, depending on the oper-
ating conditions.
Clogged filters will increase the pump’s temperature.
2 Only original filter elements guarantee the function of the pressure relief
valve.

1 Description
1.1 Design and Function
The ARS is part of the TRIVAC SYSTEM. It is an exhaust filter with oil feed-
back controlled by a float-actuated valve. It is connected to the exhaust port
of a TRIVAC B/BCS pump.
Connection of the ARS does not affect the easy modification of the pump
inlet port (vertical or horizontal installation) or the functioning of the pump’s
anti-suckback valve.
Oil mist and aerosols are trapped by the filter element, while volatile and aro-
matic substances pass through.
The oil trapped in the ARS housing is allowed to collect. When it exceeds a
certain level, the built-in float valve opens and releases the inlet aperture.
The oil is drawn out of the collector of the ARS and returned to the lubricat-
ing circuit via the feedback pipe (2/12) and the adapter (2/6) beneath the inlet
port (2/9), because when the pump is running the pressure in the collector is
higher than that beneath the inlet port. The float then drops and closes the
exhaust aperture. The oil level now gradually rising again leads to the forego-
ing procedure being repeated.
Impurities and cracking products of the oil may clog the filter elements during
operation, thus causing an overpressure in the pump.
To prevent the pressure from exceeding a specific value (approx. 1.5 bar, 7
psig), a pressure relief valve is incorporated in each exhaust filter element.
If the filter becomes clogged, the built-in pressure relief valve opens and the
filter is bypassed, thus avoiding damage caused by overpressures.
The ARS has a differential pressure indicator (2/3) to allow easy checking of
the condition of the filter elements (green: filter OK; red: change filter) .
All ARS parts that come into contact with the pumped medium are surface-
protected.
1.2 Supplied Equipment
The ARS exhaust filter with oil feedback is supplied complete with a pump
inlet adapter, connection piping with banjo bolts and all required O-ring gas-
kets as well as long fastening screws for the pump inlet port.
The ARS is pre-cleaned so that it can be used with either mineral oil (e.g.
LVO 100) or perfluoropolyether (PFPE, e.g. LVO 400).
For shipping it is sealed airtight in foil, together with silica gel.

2 Transport and Storing
The equipment must be packed in such a way, that it will not be damaged
during shipping and so that any contaminants are not released.
3 Installation
Before installing disconnect all electrical connections. You must reliably
prevent the pump from running up.
The ARS is freed of any oil and grease so that it can be used with either min-
eral oil or perfluoropolyether (PFPE). It is shipped in an airtight bag to prevent
corrosion.
Touch the interior of the ARS only with clean gloves or tools.
Work in rooms that are as clean and dry as possible.
Do not open the packaging of the ARS until immediately before use; after
opening, install the ARS as quickly as possible and start up the pump.
When using PFPE, employ only Freon®1)-113 or Frigen®2)-113 as cleaning
agent.
Since mineral oil and PFPE emulsify on coming into contact with one
another, the ARS has to be completely cleaned and equipped with new
gaskets and filter elements when changing the type of oil. It is recommend-
ed to let Leybold do this work.
Observe Safety Information 0.1.5.
If a CFS and ARS are both connected to a TRIVAC B pump, it is advisable to
replace the pump’s rubber feet with antivibration elements. The TRIVAC BCS
already has antivibration elements.

Connect the ARS to the pump’s exhaust port using the centering and clamp-
ing ring (2/4).
Loosen the lock nut (2/2) on the support bolt of the filter housing and adjust
the bolt by hand so that it rests firmly against the pump housing, thus sup-
porting the housing of the exhaust filter. Tighten the lock nut.
The surfaces of the connecting flanges must be parallel to each other and
not at an angle!
Mount the feedback pipe (2/12) with two banjo bolts (2/11) each having two
O-rings (2/10). The feedback pipe with screwed elbow joints fits precisely
and has been checked for vacuum tightness.
The quality of the couplings can be checked by measuring the pump‘s ulti-
mate pressure. The latter must not be higher with installed feedback pipe
than without.
Also fill in at (3/10) the remaining amount of oil specified in the Technical
Data.
Even when connecting the ARS, an exhaust line in accordance with safety
regulations is indispensable if toxic or other hazardous gases or vapours
are pumped.

Operation and Maintenance

4 Operation and Maintenance
By connecting the ARS, the pump‘s oil consumption becomes negligible.
This does not affect the service life of the oil. It thus remains necessary to
check the condition of the oil and change it.
PFPE does not have to be changed under normal operating conditions.
Since the ARS has a lower operating temperature than that of the pump,
condensate may gather in the ARS when pumping vapours.
Feedback of condensate (e.g. water) into the pump causes a deterioration in
the oil quality.
Please consult us in cases of doubt.
Whenever changing the pump‘s oil, change the oil in the ARS as well.
To do so, remove the oil drain plug (3/2) after the pump has been shut down
and drain the used oil into a suitable container.
Reinsert the oil-drain plug (check the gasket and replace it, if necessary).
Also fill the remaining amount of fresh oil specified in the Technical Data into
the pump at (3/10).
4.1 Replacing the Filter Elements
The filter element(s) (3/5) has/have to be replaced from time to time, depend-
ing on their conditions of use and the pump’s operating mode.
The dirtier the operating conditions and the hotter the pump gets, the more
often they have to be replaced.
The filter elements have to be replaced when the differential pressure indica-
tor (3/8) moves from green to red.
Under normal operating conditions, the filter becomes clogged by cracking
products of the oil (not PFPE). A clogged oil filter is thus a sign of a deteriora-
tion of oil quality. Whenever replacing the filter elements, the oil and any
chemical filters should also be changed.
(Description below for ARS 40-65; ARS 16-25 similar, but only one filter ele-
ment).
Tools needed

Operation and Maintenance
10 GA01297_002_A1 - 11/2014 - © Oerlikon Leybold Vacuum
Hazardous substances may escape from the filter and the oil. Take suitable
precautions (e.g. gloves, goggles or gas mask).
Observe all safety regulations.
Drain the oil (3/2) and reinsert the oil-drain plug.
Support the filter housing by placing, say, two wooden strips (3/1) under-
neath.
Remove the 4 screws (3/9) and put down the filter housing.
Loosen the small-flange connections to the pump’s exhaust port and exhaust
line and remove the lid (3/7).
Loosen 2 nuts (3/3) on the base (3/4) and remove the base.
Replace the used filter elements with new ones. Make sure that the vulcan-
ised on seal of the filter elements is seated in the centering groove in the
housing cover.
When disposing of used oil and spent filter elements, please observe the rel-
evant environmental protection regulations.
Fasten the base again with the aid of the nuts, making sure that the filter ele-
ments fit properly into the apertures in the base and the lid.
Fill oil into the filter housing (for quantity, see Technical Data).
