Do you doubt the need to clean the exhaust ventilation? The speed of air movement in the ventilation ducts of an apartment building before dryer vent cleaning is less than 0.3 meters per second. After it - 1.5 meters per second. A simple procedure increases the air exchange in the apartment by 5 times!
During operation, particles of fat and dust are deposited on the walls of the ventilation ducts. Over time, the thickness of the dusty layer can reach several centimeters.
Dirt with reverse thrust can be blown into the apartment! There is a need to clean the ventilation. Next, you will learn: how ventilation ducts are cleaned at various facilities, what equipment is needed, what disinfection is and when it is needed.
A dusty network of ventilation ducts is an excellent conductor of fire during a fire. Dry, grease-soaked dust ignites instantly, suffocating poisonous smoke spreads through the air ducts into the apartments.
Allergens, microbes, fungal spores are removed from the premises through the ventilation ducts. They settle on a dust "coat" inside and from there they can spread to neighboring apartments, making the air inhaled by people dangerous.
At the same time, good ventilation provides residents with clean air, regulates humidity, and prevents the development of mold.
duct before and after cleaning
The following signs indicate that ventilation ducts need to be cleaned in an apartment building:
dust and cobwebs collect around the ventilation grill;
dust on the floor accumulates a day after cleaning;
it becomes stuffy in the rooms, especially in the hot season, which was not previously observed.
Cleaning ventilation systems in an apartment is required much more often than city dwellers think. But this procedure can only be carried out by specialists. Residents are only allowed to clean the ventilation in the apartment, it is strictly forbidden to climb into the general house networks!
Cleaning the ventilation in the apartment
any “miracle” can appear from the general house ventilation
You can independently clean the section of the ventilation duct adjacent to the apartment. You will need the simplest equipment for cleaning ventilation:
a long wire with a metal "hedgehog" at the end;
broom or brush on a long handle;
a vacuum cleaner;
respirator, rubber gloves.
Work progress:
Remove the ventilation grill and mesh (if any), wash;
Carefully sweep the dust from the walls of the ventilation duct with a broom;
With a “hedgehog” on a wire, walk up the channel as far as you can, rotate it around the axis, scraping dirt from the walls;
Use a vacuum cleaner to collect dust from the channel.
When you take on this dirty job, be prepared to find disgusting growths of dust and sometimes even insects in the ventilation!
Self-cleaning does not always bring results. Then you need to contact a specialized company.
Companies engaged in professional cleaning of ventilation ducts are equipped with modern equipment for diagnostics and work. All procedures are carried out without disturbing people working or living in the building.
Ventilation Diagnostics
A video camera attached to the ventilation cleaning robot examines every meter of air ducts, detects blockages, blockages and the most dusty places. The ventilation cleaning robot, which is also equipped with a searchlight, travels through the air duct and transmits information to a computer monitor. The degree of contamination is determined and the ventilation system is cleaned.
Before cleaning the ventilation, the robot takes samples from the surfaces of the vein channels. Washouts are examined in the laboratory, where causative agents of tuberculosis, Staphylococcus aureus and mold spores are often found. Staphylococcus is very dangerous for restaurants and cafes, where, if it gets into food, it can cause mass poisoning. Therefore, in addition to cleaning the ventilation system, disinfection will also be necessary.
