Four Cleaning Methods For The Ac Ducts Cleaning

Method # 1 - Mechanical Cleaning

The effective method of purification, most often used to serve vertical channels. It is carried out due to the physical scraper of deposits from the walls of the air ducts.

Convenient to remove uncomplicated pollution:

dust;

cobwebs;

small stones;

Birds and rodent life products.

In fact, the purification procedure can be carried out both fully manual and automated method. The method is dry, since it does not provide for the use of detergents and any other chemistry.

However, this method is not enough to neutralize fat deposits, since the accumulations of this pollutant are very difficult to remove from the surfaces of the channel. Another disadvantage of the method is that it is extremely inconvenient to apply in ventilation systems with a complex configuration, abundance of bends and branching.

For mechanical cleansing, both simple and sufficiently complex devices are used:

The cable with a metal brush well removes deposits from surfaces. To increase efficiency, the design can be supplemented with an electrical drive, due to which the removal of the sector occurs intensively.

The combined device with brushes and a vacuum cleaner makes it possible to simultaneously and take a flare, and absorb its particles, so that they do not apply to Ventkanal.

If the mechanical cleansing occurs without using a vacuum cleaner, the scaled garbage can be removed naturally in which the air flow carries pollution with them.

When cleaning vertical channels in residential buildings with the help of hers and weights on the garbage, the garbage can fall into a special mine pocket either to settle in the opening at the entrance to the apartment. In the latter case, it must be collected to avoid the spread of dirt in housing. Therefore, the use of an additional vacuum installation remains more efficient, which is separately connected to the air duct and sucks all the dirt.

Method # 2 - Chemical cleaning foam

The method is effective for the neutralization of a fat tank, which is poorly amenable to mechanical effects. The method is most in demand in public catering establishments, in which complex ducts of kitchen hoods are most susceptible to the constant sedimentation of fat particles.

In the process of purification inside the air duct, a special composition is sprayed, which splits fat. The flare is stratified and turns away from the surface, after which its particles are carried away by the air masses or sucks with a vacuum cleaner.

A rather aggressive alkaline compounds are used as detergents. Some of them besides purifying and disinfectant properties. The concentration of the reagent is selecting a specialist, pushing out of the degree of contamination of the system.

If the foam does not kill microbes, additionally in the process of purification, the ducts are disinfected. The choice of disinfector also remains behind the employee of the company. To maximize the efficiency of the pathogen destruction procedure, it is desirable to make samples of pollution to determine the varieties of microorganisms inhabiting air ducts.

Method # 3 - Combined Purification Method

The method involves the use of mechanical devices + special cleaning foam. A similar tandem allows you to achieve good results in the presence of various types of pollution.

The procedure can be both fully manual and automated, in which vacuum devices are used to extract dirt residues.

Method # 4 - Cryogenic Blasting

In essence, this relatively new method is a kind of chemical cleansing. However, Blasting deserves separate attention due to its effectiveness and gentle action. The process involves the so-called dry ice, which is optimal to clean the walls with the properties.

Installation delivers dry ice into the air duct. The substance, in contact with the walls of Ventkanal, almost instantly begins evaporation, in the process of which microvalets are produced. Thanks to them, the contamination raid is separated from the walls, but the surface of the mine itself does not damage. Dry ice during decay is converted into carbon dioxide, which leaves the channel with a stream of fresh air.

Cleaning, safety and environmental friendliness make a cryogenic blasting with an optimal choice for use in residential and catering establishments.
