LIFA Special Cleaner 20 /
25 Multi brushing machine
Congratulations on your new LIFA Special
Cleaner 20 or 25 Multi brushing machine!
LIFA SC20 / SC25 Multi is an electrically
operated brushing machine for ventilation
ducts. These brushing machines are de-
signed for the cleaning of small and me-
dium sized, round and rectangular shaped
air ventilation ducts. The length
of the cleaning shaft is 20 meters (66 ft.,
SC20) or 25 meters (82 ft., SC25 Multi),
so it can be used in cleaning up to 35 m
(115 ft., SC20) or 46 m (151 ft., SC25 Multi)
of ventilation duct when accessed in one
duct access door to both directions.
The speciality of LIFA SC20 is its small size
and user friendliness, especially in tight and
cramped places. Due to its small size, it can
also be packed and transported very easily.
The speciality of LIFA SC25 Multi is its wide
range of different sized nozzles which can
be used to spray air, liquids and foam.
Professional’s rst choice for small (SC20:
Ø100–400 (4–16”)) and medium sized
(SC25 Multi: Ø250–800 mm (10–31,5”))
ducts. In addition, LIFA SC25 Multi can
also be used in grease duct cleaning up
to 60 cm duct diameter or duct height.
LIFA SC20 is not suitable for grease duct
cleaning.
• Operation radius 18 meters (60 ft., SC20)
or 23 meters (75 ft., SC25 Multi).
• Rotating speed can be adjusted from
225–570 rpm with a frequency converter.
• Mechanically directed rotating direction
to clockwise and counter clockwise.
• The brushed off debris is removed by
sucking it to a negative air vacuum, such
as a LIFA HepaClean 1100, 2500, 4000 or
LIFA AirClean 3500 negative air machine
unit (accessory).
The mechanical centering device for the brush is available as accessory for the LIFA Special
Cleaner brushing machine. The centering device helps to push the brush in the duct and
centers the brush in the duct so that the brush can reach all parts of the duct. The use of the
centering device is recommended especially in large and rectangular ducts.

The following safety directions must be carefully observed in order to avoid
injury to personnel or damage to the environment or to the LIFA Special Cleaner
brushing machine itself. Following these instructions will ensure the safe and
uninterrupted use of the machine.
Safety Precautions
• The equipment must not be positioned or use in places where there
is a risk of explosion or hazardous substances.
• The equipment must not get wet and it has to be protected from
moisture, vibration and wind.
• Foreign objects must not be inserted or tted into the equipment.
• The machine cannot be covered during the use.
• The user must ensure that the appliance is adjusted for the task and
that the statutory requirements are met.
1. Avoid contamination of the
environment
The machine must be kept as clean
as possible. The shaft must be
cleaned before pushing it back to
the machine. The brushes and the
shell of the cleaning shaft must be
cleaned after the work has been
completed, before transporting the
machine to another location.
2. General safety
The power must be turned off and
the power cable unplugged when
the machine is not being used. It is
forbidden to make any modications
to the brushing machine or the
accessories (for example brushes).
3. Operator safety
The person/persons performing the work must
use personal protective equipment: ltered
mouth mask, helmet, earmuffs, goggles, overall,
protection shoes and other necessary protective
equipment that the task at hand requires.
LIFA Special Cleaner brushing machines have a
strong rotating force. Clothes or hair can easily
get caught in the brush and cause damage or
accidents. The brush must always be placed
in the ventilation duct before switching on
the machine. The machine cannot be used
when the brush is outside the ventilation duct.
Because of the great rotating force, the LIFA
Special Cleaner is recommended to be used by
two persons. One person directs the shaft into
the duct while the other person feeds/draws
4
LIFA Special Cleaner 20 / 25 Multi

• LIFA Special Cleaner brushing machine
is connected to a single phase (1~)
current, 230 VAC (or 120 VAC),
50/60 Hz.
• Protective switch for motor is equipped
with a low voltage protection which
prevents the switching on if the voltage
is too low or if there is no voltage.
• Only authorised electrician may do
the repairs or installations of the
electrical components. In addition,
electrician must be authorised by the
manufacturer; otherwise the warranty
expires.
7. Noise level
The noise level of LIFA Special Cleaner is
low (70 dB) and it is not dependant of the
operating environment.
8. Transportation and operating position
During the transportation, the machine
must be tied rmly in order to prevent
any damage to the machine or people.
Before use make sure that all the compo-
nents are in place and that the machine
functions well. The machine must be
transported, used and stored in an up-
right position. The machine must be
positioned far enough from walls and
other obstacles and placed rmly and
straight. Ensure a free rotation of the
brush.
Ensure that the power supply is
reliably earthed.
Connect the device only to
grounded socket!!
the shaft and controls the rotating of the
brush.
4. Workplace conditions / overload
Make sure that the lightning, air condition-
ing, latter and trestles are sufcient. If the
brush generates static electricity or sparks
in the duct do not use these types of
brushes in the duct if there is any amma-
ble liquids, gases, dust or other sensitive
substances nearby. Use antistatic brushes
and safety ground by following the special
instructions in difcult conditions.
The permitted working temperature is
5–50 °C (41–20 °F). The gearing warms up
a bit when the machine is being used. If
the motor overheats or free rotation of the
brush has been prevented, the overheat
protection of the frequency converter
will be switched on automatically. When
the right working temperature has been
reached the motor will start working again.
The current must be switched off when it is
not being used.
5. The cleaning shaft
Check the condition of the cleaning
shaft before every use. Be careful not to
damage the shaft. If the shaft has been
damaged take immediate contact to your
local distributor. Minor scratches on the
shaft surface can be xed by coating it
again with a heat shrinkable tube. During
storage and transportation, the cleaned
shaft must always be reeled into the drum.
6. Electrical connection
• Ensure that the voltage supply and the
current responds to the information
stated in the CE-plate and the
information in the instructions.

Operating Principles
a)
c)
b)
d)
Before beginning the work, check the ductwork with a) LIFA Duct Control (accessory)
equipment and choose the suitable b) brushes and nozzles based on the size and
construction of the duct as well as the composition of the removable dirt.
• Before beginning the work, check
the ductwork channel network with
LIFA Duct Control (accessory) camera
inspection equipment. There may be
air volume controllers, noise silencers,
re dampers etc. that can be damaged
during the work.
• In large rectangular ducts, there might
be supporter poles inside the duct.
Use extra care, when dealing with
ducts equipped with supporters. When
cleaning large rectangular or round
ducts the use of LIFA centering device
(accessory) is highly recommended.
• Place the machine in a rm position.
• Choose a right sized brush (depending
on the size of the duct). Make sure
that the brush isn’t too small or big for
the duct that is going to be cleaned.

LIFA Special Cleaner 20 / 25 Multi

GREASE DUCTS: LIFA Special Cleaner 25 Multi may be used for grease duct cleanings.
Please ask us more about our grease removal concept!
brushes are meant for cleaning the
grease ducts. The combination brushes
are meant to use only in grease duct
cleaning.
• LIFA SC25 Multi: If the purpose is to
spray coating or disinfectant into the
duct at same time, place an air hose
with compressed air or low-pressure air
sprayer into the machine depending on
the purpose of use. Choose a correct
nozzle (check the accessory list).
• Make sure that the working area
is cleared and there are no extra
personnel.
• Ensure that all the employees
performing the work have adequate
protective equipment.
• Make sure that there is enough low
negative pressure in the channel
network and that LIFA HepaClean or
LIFA AirClean negative pressure unit
(NPU) is installed correctly. The brushed
off debris is removed by sucking it to
the NPU.
• Connect the machine into an electrical
network.
• It is recommended to connect an
additional grounding wire between the
brushing machine and air duct.
• Place the brush inside the ventilation
duct that is going to be cleaned.
• When the operator who is feeding the
shaft into the duct gives a permission to
start the machine, the machine can be
started.
• When the shaft is being fed to the duct
sharp angles and screws etc. that can
damage the shaft must be beware of.
• Adjust the rotating speed of the brush.
Note that when cleaning “soft” ducts
(with insulation inside) the rotating
speed should be much lower than in
normal ducts. Too high a rotation speed
may damage the ductboard surface.
• The brush must be rotated to clockwise
and counter clockwise evenly (50/50).
Use both rotating directions to achieve
the best cleaning result. In rectangular
ducts, it may be required to clean one
side rst (with rotating the brush in one
direction only) and after that another
side.
• Feed the shaft evenly into the duct
without excessive force. The use of
excessive force may harm the duct,
machine or brush and inuence on the
cleaning result. Always insert the shaft
gently and smoothly into the ductwork,
to prevent the brush from ‘jumping’ and
leaving unclean spots into the duct.
• It is also advised to use the-one-and-
only specially designed centering
device and/or shaft holder by LIFA in
big ducts and/or when full rotation
speed is being used.

Service and Maintanance
Before any maintenance work the machine has to be
plugged off from the mains!
The following maintenance and upkeep work must be done in regular basis
depending on the purpose of which the machine is being used. This enables
a trouble-free use.
General Cleanliness
Keep the machine as free from dirt and dust as possible. Dirt and grease
may cause a failure in the electrical equipments. The use of running water is
forbidden.
Cleaning of the frequency converter
Unplug the machine from the electrical network. The frequency converter
maintains its voltage for a long time after it has been unplugged from the
electrical network. When the voltage has permanently dropped the protective
casing can be removed safely. Blow compressed air gently into the frequency
converter between the slots that enables the accumulated dust to come
out. If there is dirt accumulated on the surface of the frequency changer it
can be wiped off with a damp cloth. When the protective casing is open it is
recommended to check the tightness of the binding screws. After that the
protective casing can be closed.
When the machine is in daily professional use it should be delivered to its
rst regular maintenance to the manufacturer or to repair shop that has been
authorized by the manufacturer after six months from the rst commissioning
date (approximately 100 hours). The warranty expires if the machine has not
been delivered to its rst maintenance on time.

LIFA Special Cleaner 20 / 25 Multi

Electric motor
The outside of the electric motor can be cleaned with a damp cloth. The inside of the
motor is recommended to be cleaned with compressed air. This is done by blowing
the compressed air to the air inlet of the motor.
Electrical connections
ONLY an authorized electrician can do the electrical connections and other electrical
installations. However, it is good to visually ensure that the connections are tight and
the wirings are in order.
Cleaning shaft
The cleaning shaft must be cleaned every time after use. The dirt and grease that has
collected to the plastic surface can be removed with a mild grease removal detergent
that is meant for plastic surfaces. Some lubricant (synthetic Vaseline, lubricating oil
etc.) must be put between the turnbuckle and the outer bearing in the brush adapter
regularly.
Liquid nozzles (only LIFA SC25 Multi): After use, the nozzles and the hoses should
be rinsed with water so they will not get blocked and there will be no residues of old
detergents. Corrosive detergents and solvent substances may eat into the hose.
After rinsing the hose should be run clean with compressed air.
NOTE!
Possible repairs must be carried out by the manufacturer or a servicer authorized
by Lifa Air Oy Ltd. Third party repairs will void the warranty.
