How Does a Kitchen Chimney Work?

Basic modes of operation Ask an expert a question content How the Chimney works – species dependence. To begin with, let’s look at the main types of devices. When you start your choice, you need to consider Chimneys work modes – just about complex Depending on the air circulation, the devices are divided into Extract mode – pros and cons The virtues of Chimneys with withdrawal Weaknesses of exhaust systems with a diversion into ventilation Recycling mode – pros and cons Benefits of circulating Chimneys The drawbacks of recycling devices: How kitchen Chimneys work The development of technology allows you to create maximum comfort in the room, installing several devices. One of the most useful – kitchen Chimney. It allows to eliminate odours, reduces the number of deposits on furniture and walls of fat and other sediments, and cleans the air. The variety of devices on the market can stupor users and choose the optimal option. Therefore, it is important to understand the questions – how does the Chimney work? The main modes of operation of different types of systems will also be discussed further. Whether one device is enough or, additional ventilation is needed.


How the Chimney Works 

It seemed that it could be easier than choosing a device placed above the cooking surface to capture steam and protect against odours. Perhaps earlier, when the choice was small, the buying process took little time. Today, the market is represented by many units that differ: type of work, installation principle, modes of operation, number of motors, power, appearance and other parameters. When you start choosing the optimal Chimney, you need to understand the details, which we will do in this article.

To begin with, let’s look at the main types of devices

  • Corner – allows you to save space in small rooms.
  • Decorative or design – perform not only practical but also aesthetic functions.
  • The fireplace looks like a chimney.
  • Dome – classic, the most common and popular model.
  • Monoblock – all the elements are located in the same block, filters, motor, and control system.
  • Slope – does not take up much space, provides a free approach to the cooking surface. Looks stylish and attractive.
  • Island – a new incidence in interior fashion. Attached to the ceiling, located far from the walls. It is fastened on cables or hard rods.
  • Flat – can be located as an independent element or fastened to the cupboard’s bottom above the cooking surface. Relatively thin, easily integrated into most styles.
  • Fully built – the main part of the device is located in furniture (most often a closet); in full view is only the work surface and control panel. Wall – this type includes a lot of models, which are attached to the wall with one side.
  • T-shaped – resembles the inverted letter “T”, has a flat lower part with filters and vertical – with a motor and a wing.
  • Telescopic – such devices are embedded in furniture (cabinet or countertop), ceiling or other surfaces. To start the operation, put forward a working panel. Then it is cleaned again. Almost invisible between operational moments. As with air conditioners, not only external parameters but also technical aspects are important for kitchen units.


When you start your choice, you need to consider

When you start your choice, you need to consider

Power – affects the speed of cleaning the air in the room. The best option is that all the air in the room is treated within 5 minutes. If the parameters are insufficient, the smells will spread outside the kitchen. And if excess will be the unreasonably high noise level. The middle ground is important. To calculate the optimal capacity, it is desirable to multiply the room’s volume by 10-12.

Dimensions – the work surface should not be smaller than the cooking. Otherwise, the effect will be insufficient. Some of the fat and soot settles on the adjacent furniture.

The number and types of work items – filters: absolutely all devices are equipped with rough cleaning filters – this is the first, mandatory stage of air processing. It is often aluminium plates with small holes for catching fat, soot and other large particles. The filter of fine cleaning catches small parts, eliminates odours and other invisible elements to the eye. There may be a few of them. They are made of polypropylene, compressed coconut charcoal fibres and other modern materials.

The diameter of the connection to the ventilation shaft. The minimum size of the hole on the Chimney is 100 mm. The larger the power of the unit, the larger the hole is usually. Experts also recommend having the nearest Chimney to the ventilation shaft. The minimum length of the pipeline helps to maintain the power parameters. Conversely, a long bend with a “drain” reduces efficiency.


Chimneys work modes – just about the complex.

Every day there are more and more different interior solutions. When improving the kitchen, furniture is installed along the walls and mounted in the room’s centre. This has led to a significant expansion of device performance. After all, air purification and water treatment have a huge impact on the quality and duration of life of the room’s inhabitants. Today we can distinguish two principles of kitchen Chimneys, presented in our catalogue and from different manufacturers.

Depending on the air circulation, the devices are divided into:

  • Recycling (circulation) – after the air is collected from the room, it passes through a double cleaning system, then returns to the room.
  • Diversion (withdrawal) of air – outside the room: through a hole in the wall to the street; through a home-wide ventilation system.

The second option is considered the most effective, but it is not always available for implementation. For example, if you have a cooking surface located on an island, and there is no way to lay a pipe to ventilation, you will be suitable recycling models. Modern technology has made it possible to give Chimneys several functions (modes):

  • Built-in sensors and gas analyzers allow the device to turn on without human involvement when steam, soot, smoke is detected. Also, devices can have the function of automatic power adjustment.
  • The built-in timer allows you to program the disconnection of the unit, save energy and time.
  • Most models have several speeds of operation; the user can independently choose the power optimal for the current moment through electronic or mechanical control.
  • The presence of illumination, which makes the cooking process more pleasant and convenient.


Extract mode – pros and cons

Devices with the withdrawal of “spent” air from the premises are considered more effective. They do not require the organization of additional ventilation in the form of air household recoverers, ventilators, various fans.

The virtues of Chimneys with withdrawal

  • High-quality air exchange.
  • A variety of models, ease of integration into the interior.
  • A wide range of capacity.
  • The different price range of units.
  • The work of the unit is based on the output of air outwards. Only a rough cleaning filter, which is reusable, easy to care for and clean, is used.

Weaknesses of exhaust systems with a diversion into the ventilation

  • The need to install a duct.
  • The choice of the installation site of the system directly depends on the location of the vent.
  • The longer the pipeline, the higher the loss of power. The same applies to the number of bends of the retractable pipe.
  • It is advisable to provide a reverse valve to prevent air and odours from entering the mine.
  • Designing the system, installing the device and fixing it is desirable to trust professionals. This will minimize power loss. The list of services, terms of delivery and price can be found on the website or phone.


Recycling mode – pros and cons,

Unfortunately, not all rooms have the possibility of air removal. There are several reasons for this:

  • The cooking surface is located far from the ventilation shaft;
  • There is no house ventilation at all;
  • The cooking surface is located on the island, and there is no way to lay the pipeline;
  • The model you like does not provide for air removal.

Benefits of circulating Chimneys

  • The ability to install at any point of the room – there is no attachment to ventilation.
  • Keeping the temperature indoors, as there is no influx from the outside. Threads are reversed within a confined space.
  • No reverse thrust.
  • Many models are telescopic and can “hide”, freeing up space.
  • The cost of commissioning is somewhat lower, as there is no need to lay the pipeline.
  • Multifunction.

The drawbacks of recycling devices:

  • The need to regularly change fine-cleaning filters. As a rule, they are disposable; their resource is limited.
  • It would help if you considered airing to ensure fresh air flow.
  • The older the model, the harder it is to find filters to replace.


How kitchen Chimneys work

  • Regardless of the type of device, the basic principles of operation are identical:
  • Air absorption is done through the motor with the wing.
  • The threads then pass through the first coarse cleaning filter. On its surface settles fat, soaps and large particles.
  • The next step is a thin clean-up. Paper, acrylic and coal filters are used for this purpose. In inflow systems, these filters may not exist, or they can be removed by the users themselves, as the first level of air treatment is sufficient to be released into the ventilation system.
  • In recycling devices, air through channels located on the sides enters back into the room. While at the diversion, it moves to the ventilation shaft.

No matter what type of kitchen Chimney device you choose, it is important to install and connect properly. The quality of the work depends on the work of the system and its productivity. Also do not forget about service. Change the filters promptly and clean up the system. You can order the full range of services from our experts.
