Path of the LIFA Cleaning Concept
Consulting and guidance of customers
Inspection of need for cleaning
”Parallel” photos of Visual scale, robot aided video camera, comb and sampling method
Selection of cleaning devices:
Brushing and/ air-jetting machine, brushes+accessories, negative air
machine, disinfection devices etc
Verification of the cleanliness, photos of visual scale, camera, etc,
perhaps not the same as in the first phase
The first Work document
a photo of

Documentation of the cleanliness,
Added to the building documents for
future use
The second Work document

Nozzles included in the price for CombiCleaner
15 + 40, AirJet Combi 20 and Special Cleaner 25
Multi:1) disinfectant and liquid spraying (round-small ducts)
2) air-jetting nozzle (high volume)
Accessory nozzles
Foam nozzleY-nozzle (for big
rectangular ducts)
Ball nozzle (for small +
soft surface/flexible ducts
-
Brushes – 2 connection types
1) M12 screw connection (old type), for driller shafts, SC20
Soft – hard/stiff – combination=rect ducts – special vs.
2) Brush adapter connection for brushes with nylon center
-
Comparison of old vs. new type brushes inside duct
Disk in the center of the brush greatly enhances the speed of vacuum air flow

Sprayers for application of coatings and
disinfectantsFOR AIR DUCTS/PIPES

for all LIFA machines
-
Cleaning agents, disinfectants, coatings
The ULV-technology = Ultra Low Volume is useful for quick disinfecting in the buildings and in ventilation systems.
There are two basic methods:
- Dry Fogging with by using Patriot PulsJet Fogger.
- Damp mist by using MacroMist aerosol aggregat.
These agents are peroxides.
For ductwork we are using the "wet aerosol method". The chemical used must be approved by local authorities for HVAC use (formaldehyde and chlorine based chemicals is an absolute no-no), also be aware that some chemicals corrode the duct or kill the the galvanasation.

GREASE CLEANING CONCEPT
-
Grease Cleaning Concept
• suitable for all types of grease, soft or hard-burned and both round and rectangular up to 1,2m in size
• unique capability of one machine capable of doing brushing, spraying chemicals and adsorbent granules all at the same time.
• Lifa machines are the only ones powerful and durable enough to be able to rotate a brush in a grease duct is also a decisive factor.
-
Grease Cleaning Concept
Different methods and techniques• Brushing (grease brush, cloth)
• Spreading of chemicals and brushing
• Spreading of oil adsorbent granules and brushing + air-jetting ALL AT THE SAME TIME
combined in one equipment package:• Effective for all types of grease
• In all sizes/shapes of ducts
• Machines can be used in other work also
-
Grease set equipment
SPREADING SIDE
Lifa brushing machine: unique
capability of brushing and air-
jetting/spraying liquids at the
same time
Lifa Granule Sprayer: can be
attached to CombiCleaner 40,
Special Cleaner 25 Multi (also
Hydmaster but then AirJet Combi
20 is needed too)
SUCTION SIDE
Lifa HepaClean machine: unique
filter options + combination
capability with superior vacuum
power
Lifa Preseparator Unit:
functionality and money
savings in less filter change
needs; attached to HC 2500,
HC 4000, AC 7000
-
Spreading side: Granule sprayer + Lifa brushing
machine
Special Cleaner 25 CombiCleaner 40 + 15 - pneumatic
Can be attached to
Hydmaster 40 also Granule Sprayer
-
Spreading side:
Granule + chemical spraying
• Hard grease that
doesn’t come off with
brushing need to be
softened with grease
detergent, foam best
• Liquidy grease is
adsorbed into oil
adsorbent granule,
then air-jetted and
brushed out into
preseparator
-
Nozzles for spraying chemicals and air-jetting
• BASIC SET (incl. In
machines): left ”liquid with
back pressure valve”; right is
”high volume air”
• ”foam nozzle”
• Y-nozzle small or big with
bending arms: for air-jetting in
rectangular ducts
-
Spreading side: brushes for grease cleaning
• Grease chopper 2 adjustable sizes: with Hydmaster and CC40/15 only, limited use
• Tynex brush: abrasive ”metal-sand-paper-like”; bristles bend = ”digs” into corners rectangular ducts
• Metal razor brush:100-400 mm Very sharp ends cuts both solid+sticky grease off. NEEDS TO BE EXACTLY OR SMALLER THAN DUCT !
• Grease brush with nylon center (hard duct brush): stiff 1,0 mm nylon bristles very hard, little bending = must be exactly or smaller than size of duct
• Grease brush M12: most ”aggressive” brush; 2,5 mm nylon bristles very stiff, no bending = must be exactly size of duc
-
Suction side: Preseparator (cyclone / gravitational
filter unit + Lifa negative air machine
Air flow is simply controlled
by damper: in minimum when
spreading granules, max when
brushing and/or air-jetting
Removes all heavy and greasy dirt
before normal filters into a waste bag
• easily removed and disposed
• savings in normal filters
-
Filter options
Prefilter box enables to use 2 different filters at the sametime, any combination: • EU4 (G4) bag filter or filter
mat• EU7 (F7) bag filter
• Lifa Fp7 particle and odourbag filter
• Hepa filter / gas filter
