Description
PUREBERG FWW cyclone separators have been developed for high efficient removal of bulk liquids from
compressed air(1) and vacuum systems. Inside the housing there is an insert with vanes that creates
controlled rotation of the air. As a result of centrifugal action liquids (water, oil) and large particles are
forced to the housing wall, slowed down and accumulated at the bottom of separator housing as
condensate. The turbulent free zone in the lower part of the filter housing prevents condensate from
being picked up and “carried over” into the airstream.
To discharge condensate from the FWW cyclone separator it is essential to install automatic or
electronic condensate drain.

CORRECTION FACTORS
To calculate the correct capacity of a given cyclone based on actual operating conditions, multiply the nominal flow capacity
by the appropriate correction factor(s).
CORRECTED CAPACITY = NOMINAL FLOW CAPACITY x COP

There is Technical datasheet available. For additional technical specification, contact manufacturer.
Safety instructions
The relevant safety at work and accident prevention regulations, plus operating instructions, shall apply
for operating the cyclone. The cyclone has been constructed in accordance with the generally
recognized rules of engineering. It complies with the requirements of directive PED 2014/68/EU
concerning pressure equipment.
Ensure that installation complies with local laws for operation and routine testing of pressure
equipment at the place of installation.
Operator/user of the cyclone should make himself familiar with the function, installation and start-up of
the unit. All the safety information is always intended to ensure your personal safety.
Do not exceed max. operating pressure or operating temperature range (see data label).
The permissible working temperatures and pressures for ad-on parts and separator elements are
given under Technical data for those ad-ons. Maximum temperature and pressure for assembled
system is the lowest of any individual part.
It is necessary to ensure that the unit is equipped with the corresponding safety and test devices
to prevent the permissible operating parameters from being exceeded.
Separator has been designed for a primarily static pressure. Rapid changes of pressure are not
allowed.
Ensure that the separator is not subject to vibrations that could cause fatigue fractures.
Separator is not to be subjected to mechanical stresses.
The medium used may not have any corrosive components that could attack the materials of the
separator in a way that is not permitted. Do not use the separator in hazardous areas with
potentially explosive atmospheres.
All installation and maintenance work on the separator may only be carried out by trained and
experienced specialists.
It is forbidden to carry out any kind of work on the separator and piping, including welding and
constructional changes, etc.
A pressure gauge, which shows the operational pressure, must be installed in the unit,
respectively in the pipeline.
Depressurize the system before carrying out the installation work. The unit must be installed
vertically in the piping.
Ensure that separator is installed without any stresses.
Use original spare parts only.
Use the device for appropriate purpose only.

Appropriate use
FWW series cyclone separators are designed for high efficient removal of bulk liquids from
compressed air and vacuum systems. This appliance must be used only for the purpose for
which it was specifically designed. All other uses are to be considered incorrect and will void
warranty.
Specifically:
cyclone can only be used for “GROUPE 2” fluids (PED 2014/68/EU).
cyclone can not be used for explosive, toxic, flammable, corrosive and “GROUPE 1” fluids (PED
2014/68/EU).
Warning: internal corrosion can seriously reduce the safety of installation: check it during changing the
cartridge.
The manufacturer will under no circumstances be responsible for any damage resulting from improper,
incorrect or unreasonable use.
Use genuine spare parts only. Any damage or malfunction caused by the use of ungenuine parts is not
covered by Warranty or Product Liability.

Installation
Transportation of cyclone is carried on a pallet, fixed with soft rope wrapped around jacket to prevent
slippage. Cyclone can be hand over to market and operation only in case, if it is properly installed and
used for intended purpose. Installation must not be dangerous for health and safety of people. There
must be enough space for undisturbed inspection and maintenance.
Cyclone must ensure safety and reliably operation. Cyclone must be protected against injuries and non-
authorized substitution. Operating pressure must correspond to design pressure. Cyclone must be
connected to pipeline with controlled pressure, which cannot exceed values of the max. working
(operating) pressure.
Cyclone must have all necessary technical documentation. It must be regularly checked and maintained
in accordance with technical and state regulations. Instructions for handling in the case of emergency
must hang on the visible place near the vessel. In case of explosion, operating process must be stopped
immediately.

Maintenance
To prevent air leakage and malfunction replace housing O-ring if necessary. For replacement
contact manufacturer.
Damaged components are to be replaced by new ones. If a marked degree of damage is found,
the entire cyclone is to be replaced.
Cyclone has been designed for a life of 10 years in normal operating environment. After 10 years
periodical checks of cyclone integrity are strongly recommended for safe operation.
Carry out a check for leaks once the maintenance work has been finished.
Warranty exclusion
The guarantee shall be void if:
The operating instructions were not followed with respect to initial commissioning and
maintenance.
The unit was not operated properly and appropriately.
The unit was operated when it was clearly defective.
Non-original spare parts or replacement parts were used.
The unit was not operated within the permissible technical parameters.
Unauthorised constructional changes were made to the unit or if parts of the unit that may not
be opened were dismantled.
