Detailed description of goods
An inspection of purity of ventilating channels is usually carried out by sampling and carrying out checks by sensors via control hatches, entrance and output air valves. Usually it is not possible to examine the ventilating channel on all its length, and quality check of cleaning is carried out only via control hatches.
The Lifa Air company created advanced technologies of control over a condition of system of ventilation. Lifa Air developed the remote operated systems equipped with video cameras by means of which it is possible to find out need of cleaning of these or those sites and also to estimate quality of the carried-out works.
40 polluting substances get to the room through ventilating system. Distances between filters quite often too big, and the polluted air can not get to these filters. Irrespective of existence of filters in ventilating system some polluting substances in the form of small particles will get from external air and will accumulate on an internal surface of the ventilating equipment or will get to the room. And there is more to come. The polluting substances can accumulate during production, transportation, storage and installation of the ventilating equipment, reducing thereby quality of the arriving air. The new ventilating equipment contains an oil raid. The equipment transported and stored unpacked may contain the polluting substances from external air and the soil. In an installation time of the ventilating equipment in it cement dust or metal shaving can accumulate.
As fertile field for microbes the dirt collecting in the ventilating equipment, on walls of ventilating channels, on the elements various heating, cooling, moistening and air-giving can serve.
Quality of air indoors often suffers because of violation of norms of operation, and also, design errors. It is possible to find in ventilating channels which were never cleaned anything, beginning from construction debris and finishing with skeletons and excrement of animals. The air ducts polluted by organic waste can turn into a nursery of various diseases which extend on ventilating system of all building.
