A comprehensive solution for the cleaning of LIFA ventilation systems.
The solution includes:
criteria of purity
visual assessment methods
plan of treatment works
aqir lines after cleaning
optimal choice of cleaning method
control system of cleaning quality
The system of remote monitoring, by means of which you can find out the need to clean one or another area, as well as assess the quality of the cleaning.
Checking the purity of the ventilation ducts is usually carried out by taking samples and carrying out checks by sensors through control hatches, inlet and outlet air valves. Usually, the ventilation duct can not be inspected along its entire length, and the quality control is checked only through control hatches.
Lifa Air Company has developed advanced technologies for controlling the state of the ventilation system. Lifa Air has developed remote controlled systems equipped with video cameras, which help you find out the need to clean up these or other sites, as well as assess the quality of the work performed.
40% of pollutants enter the premises through the ventilation system. The distance between the filters is often very high, and contaminated air may not get into these filters. Regardless of the presence of filters in the ventilation system, some pollutants in the form of small particles penetrate from the outside air and settle on the inner surface of the ventilation equipment or will enter the room. And that’s not all. Pollutants can accumulate during the manufacture, transport, storage and installation of ventilation equipment, thus reducing the quality of the air supplied. The new ventilation equipment contains an oil spill. Equipment that is transported and stored unpackaged may contain contaminants from the outside air and soil. When installing ventilation equipment it can accumulate cement dust or metal chips.
Favorable soil for microbes can serve as dirt accumulated in ventilation equipment, on the walls of ventilation ducts, on various heating, cooling, moisturizing and air supplying elements.
The air quality inside the premises often suffers from a violation of operating standards, as well as design errors. In ventilation ducts that have never been cleaned, you can find everything from construction debris to skeletons and animal excrements. Airways polluted with organic waste can turn into a nursery of various diseases that spread through the ventilation system of the entire building.
Rules for cleaning ventilation ducts
So far in Finland ventilation systems have been cleaned on a voluntary basis. The standards for the maintenance of ventilation systems were designed to provide fire safety. Dust and grease accumulated in exhaust ducts are considered as fire hazardous, and their removal is officially controlled.
According to the rules of the Ministry of Internal Affairs of Finland ventilation equipment must prochyschatysya at least once a year, in compliance with fire safety in these types of buildings:
buildings for industrial food production
industrial buildings in which air ducts accumulate a large amount of flammable material
buildings where flammable liquids are produced or used
The state of the ventilation equipment must be checked not later than every 5 years:
in medical, correctional and social institutions
places of residence and food (hotels, restaurants, etc.)
(With regard to Moscow, given that the environmental environment is worse, the frequency of purification is reduced by about twice)
The Finnish Society for the control of the air (Indoor Air Society) indoors defined the classes of its purification for ventilation systems. Two classes, 1 st and 2 nd, are used for new ventilation systems. 1st grade means a higher level for residential and industrial premises, the 2nd class meets the officially admissible requirements.
The average dust concentration in the ventilation system before the first “start” should be no more than 1.0g / m2 in class 1 and no more than 2.5 g / m2 in class 2.
Tidal air ducts should be cleaned at least once every five years, if the dust concentration exceeds 2.0 g / m2 for the 1st class and 5.0 g / m2 for the 2nd class.
