2.2 Safety instructions
All safety instructions in this document are based on the results of the risk assessment. Where applica-
ble, all life cycle phases of the product were taken into account.
Risks during installation
CAUTION
Risk of poisoning from toxic process gases escaping in the event of overpressure
There is risk of exhaust gases and vapors escaping freely into the open air, if the interior pressure
exceeds the permissible value of the SAS. In processes involving toxic media, there is a risk of injury
and danger to life from poisoning by escaping gas.
►Install an exhaust duct in such a way that no overpressure develops in the line.
►Install the exhaust line without additional shut-off units.
Safety
6/30

Risks during maintenance
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
CAUTION
Health hazard from increased dust emission
Cleaning with compressed air causes increased dust emission. There is risk of injuring your respira-
tory organs.
►Clean the dust separator outdoors, if possible.
►Wear a respiratory mask.

3 Product description
3.1 Function
The dust separator protects the vacuum pump from dust particles from the process. Mounted on the
intake side of the vacuum pump, it separates dust particles from the pumped gas flow. The filter insert is
made of polyester. The media flows through it from the outside to the inside. Alternatively, a filter insert
made of paper is available.
In the case of oil-free vacuum pumps, mounting the dust separator on the exhaust protects the environ-
ment by filtering dust and particles from the pumped gas flow.

4 Storage
We recommend
Pfeiffer Vacuum recommends storing the products in their original transport packaging.
The filter inserts can absorb moisture, which can negatively influence the filtering effect and service life.
Store SAS
1. Store the SAS only in dry, dust-free rooms, within the specified ambient conditions.
2. In rooms with humid or aggressive atmospheres: Hermetically seal the SAS together with a drying
agent in a plastic bag.

6 Operation
NOTICE
Damage to dust separator due to excess temperature
The max. permissible gas inlet temperature for the SAS is 104 °C. Higher temperatures cause dam-
age to the filter insert and the seals.
►Operate the dust separator only when the seals are in proper condition.
►Observe the max. permissible inlet temperature.
Check differential pressure of the SAS
●If the differential pressure exceeds the initial value by 25 – 40 hPa, ensure that a re-
placement filter insert is available.
●Clean or replace the filter insert at the latest when the differential pressure exceeds the
initial value by 40 – 50 hPa.
Notes on before and during operation, for use on vacuum side
1. Regularly check the condition of all seals.
–The seals always have to lie evenly on the end cover.
2. Regularly check the differential pressure of the SAS.
–Measure and note the pressure loss at the beginning of the evacuation phase with a clean
filter insert.
3. Compare the pressure loss with the values that occur during operation.
4. Clean or replace the filter insert at the latest when the differential pressure exceeds the initial val-
ue by 40 – 50 hPa.
Notes on before and during operation, for use on exhaust side
1. Regularly check the condition of all seals.
–The seals always have to lie evenly on the end cover.
2. Regularly check the filter insert for soiling.
–When the through-flow matches the specified direction, the cover acts as safety valve.

7 Maintenance
7.1 Remove filter insert
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
NOTICE
Damage to the vacuum pump due to damaged filter inserts
Using unsuitable aids and cleaning agents for disassembly and cleaning can potentially result in
damage to the filter inserts. Unfiltered particles enter the vacuum pump and cause damage.
►Never use sharp-edged, metallic tools.
►Observe the specified cleaning procedure.
►Use approved cleaning agents only to clean filter inserts.
NOTICE
Damage to sealing surfaces from unsuitable tools
The use of unsuitable tools for removal or insertion of sealing rings damages the sealing surfaces,
causing vacuum pump leakage.
►Never use sharp, metallic tools (e.g. tweezers).
►Only remove sealing rings with an O-ring picker.
Signs that indicate saturation of the filter insert:
●Pressure loss exceeds the initial value by 40 – 50 hPa
●Vacuum pump does not achieve the initial throughput
Prerequisites
●Vacuum pump switched off
●Vacuum line or exhaust line vented to atmospheric pressure
●SAS has cooled sufficiently to be touched
