LIFA CONCEPT consists of: • criteria for cleaning and results • methods for visual Ventilation Hygiene evaluation of cleanliness • plans for cleaning • advanced cleaning machines and techniques Packages • quality assurance systems and training materials Accesories, brushes Cleaning Machines Vacuum machines Cameras etc. 1 Lifa Air presentation 2018

Path of the LIFA Cleaning Concept Consulting and guidance of customers The first Work document Inspection of need for cleaning ”Parallel” photos of Visual scale, robot aided video camera, comb and sampling method a photo of dirty duct 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, The second Work document perhaps not the same as in the first phase a photo of clean duct document for Documentation of the cleanliness, authorities if Added to the building documents for needed future use Lifa Air Oy Ltd. • Vellamonkatu 30 B, 00550 Helsinki, Finland • Tel: +358 9 394 858

Video inspection equipment - DuctControl Manual: drop cam + glass fibre rod on reel, for small ducts - DuctControl Mini: remote controlled driveable camera robot, for ducts 16-70cm - DuctControl Cleaning Robot: compressor powering the brush motor, for ducts 20-70cm in height -New 2011: back camera included in both DC Mini and DC Cleaaning Robot

ACCESSORIES HYDMASTER AND COMBI CLEANER 40 3-brush-gear: for low (100- Y-gear for rectangular ducts 200mm) height but very wide >300mm in height – rotating 2 brushes at the same time (400-1000mm) ducts

Brushing machines, robots 8 kg, 18cm height 22 kg, Up to 70cm 35cm height Width 25cm, Up to 1,2m Cable length Cable length 30m 30m

CENTERING DEVICES Pneumatic centralizer for CombiCleaner 40, inflating+deflating remotely from switch Mechanical one for Hy40, SC25, CC15

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 Y-nozzle (for big Ball nozzle (for small + Foam nozzle soft surface/flexible ducts rectangular 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 New type Old type Disk in the center of the brush greatly enhances the speed of vacuum air flow

Sprayers for application of coatings and disinfectants FOR AIR DUCTS/PIPES Dry-fogging unit for open spaces Spray bottle 5l (manual) – ULV spray unit for all LIFA machines (electric)

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.

Personal safety, respirators, overalls etc

GREASE CLEANING CONCEPT

Grease Cleaning Concept • s uitable 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 SUCTION SIDE Lifa HepaClean machine: unique Lifa brushing machine: unique filter options + combination capability of brushing and air- capability with superior vacuum jetting/spraying liquids at the power same time Lifa Preseparator Unit: Lifa Granule Sprayer: can be functionality and money attached to CombiCleaner 40, savings in less filter change Special Cleaner 25 Multi (also needs; attached to HC 2500, Hydmaster but then AirJet Combi HC 4000, AC 7000 20 is needed too)

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
