Safety instructions
The relevant safety at work and accident prevention regulations, plus operating instructions,
shall apply for operating the filter. The filter has been constructed in accordance with the
generally recognized rules of engineering. It complies with the requirements of directive
2014/68/EUconcerning 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 filter 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
filter 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.
Filter has been designed for a primarily static pressure. Rapid changes of
pressure are not allowed.
Ensure that the filter is not subject to vibrations that could cause fatigue
fractures.
Filter is not to be subjected to mechanical stresses.
The medium used may not have any corrosive components that could attack
the materials of the filter in a way that is not permitted. Do not use the filter
in hazardous areas with potentially explosive atmospheres.
All installation and maintenance work on the filter may only be carried out by
trained and experienced specialists.
It is forbidden to carry out any kind of work on the filter 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 filter is installed without any stresses.
Use original spare parts only.
Use the device for appropriate purpose only.

Appropriate use
AFs series filters are designed for high efficient removal of solid particles, water,
oil aerosols, hydrocarbons, odour and vapours from compressed air systems. This
appliance must be used only for the purpose for which it was specifically designed.
All other uses are to be considered incorrect.
Specifically:
Filter is not intended for human breathing without proper additional equipment.
Filter can only be used for “GROUPE 2” fluids (PED 2014/68/EU).
Filter 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
Operations should be performed only by qualified personnel. Never operate with installation
under pressure. The user is responsible to ensure that the filter will never operate at
pressure exceeding the nominal values. Eventual over-pressure could be dangerous and
hazardous to the operator and the equipment.
Models AFs 0056 to AFs 0706
The filter assembly and installation procedures are as follows:
•If provided, install the pressure drop indicator or the Differential Pressure Gauge
(optional) on the filter head.
•Connect the filter head to the compressed air piping and check that the airflow
corresponds to the direction of the arrow positioned on the filter head cap.
•Clean accurately the piping and the filter head outlets, remove any shaving, slaver or
scrap from tooling.

AFs - Installation and operating manual

•Lubricate the O-ring and the sealing surfaces of the filter head and cartridge, use
multipurpose grease (SILICONE FREE).
•Fit the filter cartridge on the filter head simply by pressing, tightness is ensured by
one o-ring.
•Fit the filter bowl and tight it accurately.
•Filters must always be installed in a vertical position with sufficient space around. The
minimum distance (D in the technical data table) has to be assured under the filter
bowl, which is necessary for filter cartridge changing.
•Stick the adhesive label showing the month and year for the next filtering element
change (max. one year) on the filter bowl.
•Slowly pressurize the installation and check it for air leakage.
Models AFs 0946 to AFs 2406
The filter assembly and installation procedures are as follows:
•If provided, install the pressure drop indicator or the Differential Pressure Gauge
(optional) on the filter head.
•Connect the filter head to the compressed air piping and check that the airflow
corresponds to the direction of the arrow positioned on the filter head cap.
•Clean accurately the piping and the filter head outlets, remove any shaving, slaver or
scrap from tooling.
•Lubricate the O-ring and the sealing surfaces of the filter head and cartridge. Use
multi-purpose grease (SILICONE FREE).
•Fit the filter cartridge on the filter head centering the filter bottom hole with the
screwed rod. Tight the hexagonal nut and fix the element.
•Fit the filter bowl and tight it accurately.
•Filters must always be installed in a vertical position with sufficient space around. The
minimum distance (D in the technical data table) has to be assured under the filter
bowl, which is necessary for filter cartridge changing.
•Stick the adhesive label showing the month and year for the next filtering element
change (max. one year) on the filter bowl.
•Slowly pressurize the installation and check for air leakage.

Starting up
•Check that the operating data (pressure, temperature and flow-rate) do not exceed
values on the specification plate.
•Close the on-off valve (V1) downstream of the filter, slowly open the on-off valve (V2)
upstream to the filter, and let the air flow from the manual or automatic drain valve
for a few minutes; close the drain valve and slowly open the on-off valve (V1) down-
line from the filter.
Operation
•Ensure trouble-free operation of condensate drain. Check At least once a week if
condensate drain operates regularly.
•If installed, regularly check pressure drop indicator to ensure filter element is not
saturated and pressure drop is within acceptable limits.
If a filter grade A is installed, check the good efficiency of the pre-filters, otherwise the
presence of any oil and water aerosols make the absorption power of the filter void.

Maintenance
Filter elements are subject to wear. In order to maintain system efficiency, optimal
performance and best air quality, these rules of proper maintenance should be followed:
Ms and Ss filter grades at least once per year or when pressure drop reaches
350mbar.
The housing O-ring can be damaged during filter element change. 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 filter is to be replaced.
Filter has been designed for a life of 10 years in normal operating environment. After 10
years periodical checks of filter 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.
