Cleaning of ventilation systems

Few things have such an impact on human health and performance as the quality of the surrounding air. Polluted air is constant headaches, drowsiness, fatigue, bad mood, allergic reactions and a high probability of various diseases. In order to purify the air in buildings, ventilation systems are installed, which are especially relevant in shopping and business centers, catering establishments and factories.

The ventilation system gradually gets dirty, and even regular replacement of filters does not prevent the appearance of dust and debris on the surface of the air ducts, which are an ideal breeding ground for bacteria, mold, corrosion of mechanical parts, etc. As the layer of dirt in the ventilation ducts increases, the force of the air flow will decrease, and subsequently a complete blockage of the ventilation system is possible, especially this should be avoided in rooms where systems with fans are installed. The accumulation of dust on work surfaces leads to a decrease in productivity, and then to overheating and equipment failure. Moreover, there is a risk of fires in contaminated ventilation ducts.

The capacity of this segment of the service market is quite large, since there are thousands of buildings in large cities in which it is necessary to regularly clean the ventilation. The competition is still small, the repetition of orders is very likely. With an extensive customer base, the company can easily serve its region.

The starting capital for opening a company that cleans ventilation systems ranges from 600 thousand rubles to 1 million 800 thousand. It all depends on which enterprises you plan to serve. Equipment sets vary in power and performance, but all consist of brush equipment, vacuum equipment and a filter unit.

The cheapest set of equipment for cleaning ventilation systems costs about 300 thousand rubles. Vehicles will be needed to transport people and equipment. Renting an office is not necessary, as equipment can be stored at home or in a garage, and meetings with clients usually take place on their premises.

At the initial stage, it takes a lot of effort and money to advertise the service, since not everyone is aware of how dangerous it is to neglect ventilation cleaning. As practice shows, the successful start of an enterprise can only be ensured by the active work of a sales manager. Advertisements are not enough, the best way is to reach out to building managers, supply managers, etc. The company will not interfere with its own website, which will contain information about the importance of the services provided and place price lists.

The cost of services is from 150 to 900 rubles per linear meter of the ventilation duct. Fluctuations in price are due to varying degrees of difficulty of access, the height of the canals, the degree of pollution, and the need for additional work. The very work of cleaning the ventilation is simple, most of the resources are spent on preparing and connecting the equipment. During the working day, you can clean 100-150 meters of ventilation.

The first stage of work is a demonstration to the client of the degree of contamination of ventilation, which is carried out using video equipment mounted on robots. As a rule, after this procedure, contracts for the maintenance of ventilation are concluded, since usually people do not even suspect what they actually breathe. In order to attract customers, you can offer free diagnostics of the degree of contamination of ventilation. The ventilation inspection robot is a four-wheeled device weighing 10-12 kilograms and measuring approximately 450x150x350 mm, equipped with a long cable. Such a device is used to inspect horizontal ventilation; to inspect vertical sections, similar devices of lower weight and without wheels are used.

To carry out the actual cleaning, first of all, the openings, channels and valves of the ventilation system are blocked. Then, a filter-ventilation unit (vacuum machine) and a ventilation cleaning unit with a flexible shaft are used. The mobile filter-ventilation unit is attached to the air duct using a corrugated sleeve and creates a high negative pressure in the ventilation duct, due to which the air passes through the unit’s filters, in which fungal spores, bacteria, viruses, dust particles, quartz, asbestos, sawdust and other harmful particles settle. human substance. Filters for the unit are selected based on the characteristics of the facility on which the work is performed.

The flexible shaft ventilation cleaning unit consists of a trolley, a drive, a drum, a flexible shaft with a length of 20 to 40 meters and a cleaning brush. Such a unit works in tandem with a vacuum installation. Cleaning machines can be equipped with an electric, mechanical, pneumatic or hydraulic drive.

After the work is completed, the ventilation system is again inspected using a video robot.

To clean the ventilation ducts in industrial enterprises and food production, special equipment is required, since the usual one may not be able to cope with a large amount of fat deposited on the walls of the air ducts. The specialized complex includes a brush machine with unique nozzles for active foam supply and a built-in video inspection system, a vane compressor capable of operating indefinitely for a long time, a foam generator with a constant temperature regime. Such equipment successfully cleans ventilation in slaughterhouses, sausage shops, barbecue shops, etc. Two people are enough to service the units. The cost of cleaning ventilation from grease is about three times higher than regular cleaning from dust.

Some manufacturers of equipment for cleaning ventilation systems that promote their products on the Russian market offer their customers the development of business plans and full information support on technical and marketing issues. According to them, the payback of such a business is a rhetorical question.
