Dirt can be blown into the apartment during reverse draft! The need to clean the ventilation is brewing. Next, you will learn: how ventilation ducts are cleaned at various facilities, what equipment is needed, what disinfection is and when it is needed.
The need to clean the ventilation
A dusty network of ventilation ducts is an excellent conductor of fire during a fire. Dry, greasy dust ignites instantly, suffocating poisonous smoke spreads through the air ducts into apartments.
Allergens, microbes, fungal spores are removed from the premises through ventilation ducts. They settle on a dusty "fur coat" inside and from there 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 mold growth.
The following signs indicate that ventilation ducts need cleaning in an apartment building:
dust, cobwebs collect around the ventilation grill;
dust accumulates on the floor a day after cleaning;
the rooms become stuffy, especially in the hot season, which was not previously observed.
Cleaning of 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 common house networks!
Cleaning ventilation in the apartment
You can independently clean the section of the ventilation duct adjacent to the apartment. You will need the simplest equipment for cleaning ventilation:
long wire with a metal "hedgehog" at the end;
broom or brush with a long handle;
vacuum cleaner;
respirator, rubber gloves.
Work progress:
Remove the ventilation grill and mesh (if any), wash;
Carefully sweep away 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 its axis, scraping dirt off the walls;
Vacuum the dust from the canal.
When taking on this dirty job, be prepared to find disgusting build-ups of dust and sometimes even insects in the ventilation! Self-cleaning does not always bring results. Then you need to contact a specialized company Air Duct Cleaning New York
Professional ventilation cleaning
Companies involved in professional cleaning of ventilation ducts are equipped with modern equipment for diagnostics and work. All procedures are carried out without the disturbance of people working or living in the building.
Ventilation diagnostics
A video camera attached to a ventilation cleaning robot examines every meter of air ducts, detects blockages, blockages and the most dusty places. A ventilation cleaning robot, equipped with a spotlight, travels through the 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 ventilation ducts. The washings are tested in the laboratory, where the causative agents of tuberculosis, Staphylococcus aureus and mold spores are often found. Staphylococcus aureus is very dangerous for restaurants and cafes, where, once ingested, it can cause massive poisoning. Therefore, in addition to cleaning the ventilation system, disinfection will also be necessary.
Complex cleaning of large ventilation systems includes:
cleaning of ventilation shafts and chambers;
cleaning the blades of the supply and exhaust fans;
cleaning of air ducts of especially large diameters;
removing dirt from the walls of small diameter ventilation ducts;
replacement of filters.
There are two ways to professionally clean the ventilation system:
mechanical;
chemical.
Industrial methods allow you to clean even dense fat deposits from the walls of air ducts and disinfect surfaces.
Preventive cleanings are essential to maintain the operating condition of mechanical exhaust ventilation systems. In some cases, it is necessary to disassemble the air ducts for better cleaning of individual areas or install hatches.
If the ventilation is equipped with inspection windows and openings, CIP cleaning is possible.
Types of ventilation cleaning equipment:
electromechanical installations;
high pressure vacuum installations;
industrial vacuum cleaners;
installations with turbines and pneumatic drive for brushes;
equipment for processing ventilation ducts with chemical reagents;
filtration installations.
In the mechanical method of cleaning ventilation ducts, industrial vacuum cleaners, compressed air installations, and cleaning mechanisms are used.
The ventilation network is divided into sections, from one end of the section a filtration unit works, from the other there is a cleaning mechanism. It is a rigid brush mounted on a flexible shaft. The shaft length can be up to 30 m.
Cleaning ventilation ducts
Ventilation systems of large enterprises usually consist of large-diameter air ducts located at a height, so cleaning work presents certain difficulties. In some cases, cleaning is carried out with conventional brush mechanisms with enlarged brushes. Sometimes people in protective suits and masks with special vacuum cleaners descend directly into the canal. In some cases, scaffolding is erected to penetrate the air ducts, and hatches are made in their walls.
The chemical method is based on the effect of substances on dust and mud deposits in the walls of air ducts. Reagents dissolve fat, soot, soot. It uses professional cleaning agents that are not available in retail.
Cleaning ventilation from fat in a restaurant
Restaurant ventilation is a grease and dust accumulator, which more than others requires periodic cleaning. The procedure is carried out by specialized firms. The ventilation in restaurants is cleaned of grease during off hours.
Oil droplets and dust particles accumulate on the inner walls of ventilation ducts, exhaust hoods, reducing the pipe clearance. The operation of the exhaust system deteriorates, the load on the fans increases. The air removed from the restaurant kitchen is most often of high temperature, so the mud and grease quickly solidifies, creating a hard layer of hard-to-remove "glaze" on the walls. An environment is formed for the development of harmful microbes, mold and fungus, which are unacceptable in catering facilities.
Cleaning the ventilation in the restaurant from the accumulated fat is carried out only with professional cleaning solutions. They are applied to the inner walls of the ventilation ducts with a spray gun and washed off under pressure. Hoods and hoods are cleaned with steam generators. Sometimes this is not enough and the hoods are treated with cleaning agents. Thick deposits of hardened fat are cleaned off with stiff brushes, metal channels are pre-frozen.
The whole process of cleaning the ventilation of the catering unit in the video:
The frequency of cleaning the ventilation ducts depends on the intensity of the hot shop. With a normal load, once every 3 months is enough, with an increased load - once every 30 days. Scheduled inspections of the sanitary condition of ventilation are carried out every 6 months. Grease traps are installed so that less fat gets into the ventilation. They do not completely solve the problem, but they reduce the area of pollution and allow you to clean the ventilation ducts less often.
Disinfection of ventilation
During cleaning of the ventilation system, the fan blades, grilles, hatches are disinfected. Disinfection is necessary if laboratory tests carried out before cleaning the ventilation reveal harmful microorganisms in the system. System disinfection is not required for routine ventilation cleanings.
For antimicrobial treatments, a single agent or complex can be used. The choice depends on the characteristics of the ventilation. The disinfectant is sprayed with a soft tube device. A suitable nozzle is put on the end of the tube, allowing the disinfectant to penetrate into the farthest cracks. In some cases, it is necessary to wipe the treated surface.
After disinfection, an act is drawn up, the quality of work is checked visually, and a laboratory analysis of washes from surfaces is done.
Ventilation cleaning equipment
Ventilation cleaning equipment includes three main components:
ventilation brushing machine;
filtering installation;
vacuum unit.
When choosing equipment, it is very important to decide which objects ventilation needs to be cleaned:
ventilation channels of apartment buildings (including garbage chute shafts) and private country houses;
catering enterprises (restaurants, bars, bakeries, cafes);
large public buildings (shopping centers, healthcare facilities, office buildings);
industrial enterprises.
Depending on this, the power and equipment configuration are selected.
Brush machines for cleaning ventilation are usually equipped with shafts of 25 - 40 meters. Pneumatic machines clean ventilation with air ducts 100 - 1200 mm in diameter. Some varieties can be supplemented with disinfection attachments.
Flexible shafts will help to get to hard-to-reach places: valves, grids, branches of the main channels, branch pipes. They are necessary for cleaning ventilation ducts in apartment buildings.
Vacuum units - the quality of the exhaust ventilation cleaning depends on their power. When working with large air ducts, the most powerful units are needed.
In addition to the above equipment from China for cleaning ventilation, it is necessary to purchase another set of brushes. There are 4 degrees of hardness of ventilation brushes: abrasive, hard, extra and standard. You will need inserts, access hatches, disinfection kits and a centering device.
The best equipment is presented by European manufacturers. But it is quite expensive. The electrical part is sensitive to power surges. Therefore, many people opt for ventilation cleaning equipment from China. It is cheaper, although the quality of the technology is often unsatisfactory. When buying Chinese ventilation cleaning equipment, you should stop at large manufacturers offering world-class equipment.
The times when we swept with a broom have sunk into the distant past. However, many of us are familiar with weak vacuum cleaners, which do not make cleaning very easy. Choosing the right vacuum cleaner is not easy. What to look for when buying? We will tell you in today's article - https://kstech.com.ua/
Dust collector type in the vacuum cleaner
There are 3 types of dust collector:
Bags . The main advantage of vacuum cleaners with bags is their low price. In the future, of course, you will have to spend money on replacing consumables, but initially they are cheaper. However, changing bags is not very convenient. In addition, if this is not done in time, bacteria will appear inside, and this is already dangerous to health. If you want to save money in the future, get a vacuum cleaner with textile bags. They can be used many times by simply washing them off from time to time.
Containers. Vacuum cleaners with containers belong to the middle price category. They are slightly more expensive than most bagged vacuum cleaners, but are easier to handle and safer for your health. They have a fairly high level of filtration. The main disadvantage of such models is the high noise level arising from the resonance of the container.
Aquafilter. Vacuum cleaners with an aquafilter are the most expensive, but at the same time the safest and most effective. They not only do an excellent job of filtering the air, but also humidify it. In order to remove the dust accumulated after the repair, you just need to pour out the dirty water from a special container. But in addition to the high price, models with an aquafilter have one more drawback - large dimensions. That is why vacuum cleaners with an aquafilter are not recommended for small apartments.
Vacuum cleaner suction power for apartment
Most often, manufacturers indicate the power on the packaging, which determines only the quality of energy consumption and the noise level. The quality of cleaning is determined by a completely different parameter - the noise level. As impressive as the power is, the main thing is that the suction power is at least 260 W. Otherwise, the cleaning will be too shallow. If you don't have a Persian cat or Persian rugs, a vacuum cleaner with a suction power of 300 W will suffice.
Filtration
Once in the hose, the air then passes through the filters and returns to the room. If the filters are of high quality, no more than 0.5% of dust gets back, this is with a filtration degree of HEPA 12 - it is the most common. If there is more dust, allergens are sprayed into the air. Such dust is more dangerous than dust lying in the corners. Good vacuum cleaner models are equipped with multiple filters or a HEPA filter that traps the smallest particles. But the best result is given by vacuum cleaners with a water filter - it provides air purification up to almost 100%.
Which vacuum cleaner to choose depending on the type of cleaning
Modern vacuum cleaners perform both dry and wet cleaning. Detergents perform better cleaning, but they are more expensive and larger than usual. Perhaps they are not suitable for small apartments. In any case, they will take up too much space there. But if the slightest excess of dust leads you or your loved ones to an asthma attack, it is still better to purchase a washing vacuum cleaner.
Vacuum cleaner brushes and attachments
Good brushes increase cleaning efficiency. It's good when the kit includes:
carpet brush;
brush for smooth surfaces;
narrow crevice nozzle for cleaning in corners.
If there is a pet in the house, the kit should also include a turbo brush, which perfectly cleans hair and coat.
Cord length
Of course, if your apartment is small, this parameter is not important. But the owners of cottages need cords of 8 m or more, because it is not always possible to plug the vacuum cleaner into an outlet.
Manufacturer
Premium manufacturers have proven themselves the most on the market: Karcher, Miele, Dyson. Quite good and more affordable. For example Electrolux. If you want to save money, consider vacuum cleaners brands Scarlett, Vitek, Samsung. In any case, pay attention to the fact that the manufacturer is known. After all, you purchase equipment for more than one year, and in the event of a breakdown, it is important that there is where to go and that the parts are available.

As a creative outlet, Nintendo's Animal Crossing: New Horizons has offered its players the opportunity to make some rather incredible things inspired by video games. Sometimes the work is an immense spectacle, like when one player recreated chunks of Pokemon Gold and Silver using custom design tiles, but other times the work shines just as brightly as a simple concept executed well.
Earlier today a player who goes by valor_le_loulou on Reddit uploaded a gif to the r/AnimalCrossing subreddit comprised of a series of stop motion pictures which create the effect of them playing beloved puzzler Tetris — though it's more of a brief proof of concept rather than a full-fledged game. Using the pathing unlocked alongside terraforming through a 3-star island rating, valor_le_loulou creates Tetris blocks (or Tetriminos for hardcore fans) from different colors that fall into place on a board made of fencing, and smoothly disappear as they create a full line.
What makes the gif really impressive, beyond how smooth it looks in its finished state, is how long the process clearly must have taken to get things just right. Villagers walking in the background and clouds floating by suggest a huge stretch of time goes by during the production, and as another New Horizons player points out there's even a yellow balloon caught on a frame. When asked about it, valor_le_loulou said they hesitated at first but couldn't resist shooting it down for long. If you need Buy Animal Crossing New Horizons Iron Nuggets, you can visit our site 5mmo.com.
The potential for what players can create in New Horizons thanks to its terraforming and outdoor decorating mechanics seem nearly limitless. While many have opted to recreate other video game locales or references on their deserted islands, others have made versions of real-world places like Disney's Magic Kingdom to great effect.
That creative potential, alongside the social aspects of the Nintendo Switch title (particularly relevant during an ongoing global pandemic), has made Animal Crossing: New Horizons immensely popular. During its recent fiscal year earnings call, Nintendo announced that the game has sold 13.41 million units since release, with some notable players like New York Congressional Representative Alexandria Ocasio-Cortez.
