The Lifa Ventilation hygiene concept for circular and rectangular air supply and exhaust ducts and HVAC air handling and air conditioning units. Same cleaning and investigation equipment is also used for industrial vent and pipe lines. The concept consists of: criteria for cleaning and cleaning results methods for the visual evaluation of cleanness optimal choice of the cleaning method advanced cleaning equipment and procedures quality assurance systems and education materialvacuum cleaners uk law Dirty supply air duct in a hospitalbest way to clean semi solid wooden floors Air duct after cleaningvacuum cleaner best singapore

Remote controlled video/digital camera system using a built-in mini tractor by which it is possible to survey cleaning needs and record the quality of cleaning afterwards. It is also used to reach the visual inspection to the critical parts of ductwork where access doors can�t be made. Light and small hand controlled version for vertical and very small ducts where the use of robot is not viable.

A low-pressure vacuuming unit that is adaptable to the maintenance opening or air valve site of the ventilation duct. The other valves are then covered. First the branches of the duct are cleaned using a rotary brush. (10�20 ms/s) is needed to carry the loosened dirt into the collecting filter bag of the low pressure vacuum unit. Then the filtered exhaust air is conducted outside the building. A High Efficiency Particulate Air (HEPA) filter is used when there is not a possibility to conduct the air out of the facility. The ventilation system in general Inspections of the cleanliness of ventilation ducts have normally been done by taking samples and making sensory inspections via the inspection hatches and at the incoming or outgoing air valves. The ducts have not normally been inspected throughout their whole length, and post-cleaning quality assurance inspections have

normally been done from the inspection hatches only. Lifa Air Ltd has done, and continues to do, much innovative development work to ensure that cleanliness inspections of the ventilation system are done thoroughly and well. Lifa Air Ltd has developed remote-controlled video camera robots and systems by which it is possible to survey cleaning needs, and check the quality of 40 % of the contaminants in indoor air come with the incoming air via the ventilation system. The distances between filters in these incoming air ducts are often too long, and impure air may flow past them. Regardless of the filters in the ventilation system, some particulate contaminants from the outdoor air will enter the system and accumulate on the inner surfaces of the ventilation equipment or flow with the incoming air into the ventilated spaces themselves. And that's not all. Contaminants may accumulate during the manufacture, transport, storage and installation of the ventilation equipment, and thus lower the quality of the incoming air.

The contaminants originating from equipment manufacture include oil residues in the ducts. transported and stored in unprotected form may collect contaminants from the outdoor air and the ground. During installation, particulate contaminants such as cement dust and metal powder may also accumulate. The dirt that collects in ventilation equipment and on duct walls and in various heat recovery, refrigerating, humidifying and air distribution equipment may act in humid conditions as a fertile The different kinds of indoor air problems derive mainly from a lack of regulations and maintenance, and partly from poor planning. Almost anything can be found in ventilation ducts that have not been cleaned - ranging from building waste to bird carcasses and excrement. Air inlets polluted by organic waste may become colonies of microbiological compounds which spread with the ventilation system throughout the whole building. Examples of various contaminants which are found in ventilation ducts or equipment and in cooling systems.

The particulate contaminants accumulated on the surfaces of ventilation systems, their sources and period Plant parts & insects Inorganic dust from ground The raw materials of sheet metal Sound and heat insulation made of mineral fibre Motors, gears and lubricants of fans Use of ventilation system. Storage, transport and installation of ventilation equipment. Installation of ventilation system. Is our present knowledge enough to identify all the effects of ventilation system contaminants on people's living environment and health? For example, if bird droppings get into the ventilation system, they may contain Histoplasma and Cryptococcus fungi or other excrement-based fungi and bacteria. is the risk to a hospital, if these fungi, when inhaled, lead to infections in patients with immunity Regulations on cleaning ventilation ducts Until now, ventilation systems have been cleaned voluntarily in Finland. ventilation systems have been drawn up to cater for fire safety, and thus they seldom relate to incoming

On the other hand, the dust and grease that accumulate in the exhaust air ducts of buildings have been regarded as a fire risk, and their cleaning is therefore officially regulated. According to the regulations of Finland's Ministry of Internal Affairs, ventilation equipment must be cleaned at least once per year for the sake of fire safety in the following types of premises: Ventilation equipment must be inspected at no longer than 5-year intervals in: places of public accommodation and/or catering (hotels, restaurants, etc.) Finland's Indoor Air Society has defined cleanliness classes for ventilation systems. C1 and C2, are used for new ventilation systems. Class 1 signifies the best possible level that can be installed in work and residential premises, while class 2 is a level that meets the The average concentration of dust in a ventilation system that is fit for sale or distribution may be no more than 1.0 g/m2 in class 1, and no more than 2.5 g/m2 in class 2.
