Typical Applications
Typical applications for the filtration unit include:
•Filtering the fluid in a hydraulic reservoir periodically as a supplement to continuous filtration
by system filters.
•Cleaning up your hydraulic system before restarting the system following component failure.
•Providing clean fluid when re-filling and adding fluid to the system reservoir.
•Reclaiming contaminated fluid.
•Pre-filling and cleaning up hydraulic systems on new or re-built machinery and equipment.
•Off-line contamination of hydraulic systems.
•Emptying waste fluid quickly.
Health, Safety & Environmental Considerations
•This equipment should only be used for its intended purpose by competent and authorised
persons, inappropriate use could cause serious injury or death.
•Prolonged contact with oil can cause damage to the skin. Appropriate PPE (personal
protective equipment) should be worn when operating the unit e.g. protective gloves, safety
glasses, safety shoes etc. Always observe local health and safety requirements.
•The unit should only be used on a flat, even surface and be attended at all times.
•Do not operate switches with wet hands.
•The unit must always be disconnected from the air supply before carrying out any routine
maintenance or repairs.
•Air and fluid hoses should be checked for any signs of damage before starting the unit.
•Ensure a spill kit is available in case of any accidental spills.
•Used filters must be disposed of in accordance with local environmental requirements.

Basic Description
The SFC-3000 portable filtration unit is a compact, self-contained filtration system, equipped with
high efficiency, high capacity filter elements capable of removing particulate contaminants and/or
water quickly, conveniently and economically. It is designed for on-site preventative maintenance
and is fitted with two standpipes and hoses for efficient fluid transfer. The suction standpipe is fitted
with a strainer to trap any large contaminants and protect the pump.
Best Efficiency
When used for recirculation filtration (as opposed to transfer filtration) position the ends of both the
inlet and outlet standpipe as far apart as possible inside the reservoir in order to ensure proper
recirculation and cleaning.
Cycle the hydraulic system thoroughly in order to flush the contaminated fluid from the lines and
system components so that all the system fluid will be filtered through the unit.
Operate the filtration cart until the total volume of the system fluid passes through the filtration cart.
For recirculation filtration, cycle the reservoir fluid through the filter cart six to eight times to ensure
the total system fluid is filtered completely.
Precautionary Measures
•The filtration unit is designed for hydraulic and lubrication oils only.
•It is not to be used for highly volatile fluids, such as gasoline, paint thinners etc.
CAUTION - DO NOT USE THE UNIT WITH THE FOLLOWING FLUIDS:
Fluids not to be used
Related dangers

Fire / Explosion
Inflammable liquids with PM <55°C

Flow Direction
Starting & Stopping
With the need valve fully closed connect the unit to a suitable air supply via the 8mm tube fitting.
Connect the suction and delivery hoses to the system/lances.
Gradually open the needle valve to regulate air flow, where the pump will start to operate.

Filtration
The unit is equipped with two filter housings which can be fitted with a range of media for removing
particulate and water contamination. If using only particle filters, it’s best to stage the filtration, i.e. a
5µm first followed by a 3µm. If a water filter is being used alongside a particulate filter it’s best to fit
the particulate filter first to protect the water absorbing filter from blocking prematurely.
To change a filter element:
1) Make sure the air supply is disconnected from the unit.
2) Open the drain port and collect the oil/fuel into a suitable waste container.
3) Remove the v-band clamp and filter bowl, along with the old filter element.
4) Fit the new element to the filter head and replace the bowl and v-band clamp. The v-band
clamp should only need to be tightened by hand.
5) Close off the drain valve before running the system.
Differential Pressure Gauge
The unit comes with differential pressure gauges that gives an indication of the filter condition via a
green, yellow and red visual indication.

Hoses & Lances
The unit is supplied with two 1" lances,
a suction lance with strainer to protect
the pump and a discharge lance. Each
lance is 1000mm long.
When not in use it is advisable to plug
the hoses and cap off the lances to
prevent ingress of dust or other
contaminants.
Lances should be cleaned prior to
inserting in the tank/barrel being
cleaned.
Suction Strainer
The suction strainer will periodically need cleaning by unscrewing the cap, removing the mesh
strainer and cleaning this out with a fluid suited for the units intended purpose e.g. hydraulic oil.

Appendix A –Achieving ISO Cleanliness Codes
Filtertechnik has a wide range of elements available to effectively achieve the required cleanliness
level for the intended system. Maintaining the fluid at the required cleanliness level is a cost-
effective way of extending the service life of system components. The tables below can be used to
determine the required micron rating of the filter to achieve the desired cleanliness code,
understand the ISO 4406 contamination scale, conversion between the various cleanliness standards
and understanding how the ISO 4406 scale relates to the NAS contamination scale.
