Every owner wants to create the most modern and comfortable conditions in his kitchen. During cooking, warm air currents create unpleasant atmospheric indicators. To avoid this, you need to install a hood with an air duct in this room. Thus, the outflow of odors will also occur.
The hood has its own design features and constituent elements. Each model has a common task and principle of operation. An important element is the air duct for the hood. He helps the threads get out of the kitchen. According to external data, this is a kind of pipe through which vapors are taken and sent outside.
Masters say that if you do not install an air duct for an exhaust hood in the kitchen, such a system will not be useful. Although there are units on sale that can cope without it. It's just that special powerful filters are placed inside. But today they have not gained popularity, as they often have to change the internal installation.
Functions
In a house or apartment where people live, there are norms according to which it is necessary to organize a suitable microclimate. It is for this reason that it is necessary to create conditions in which ventilation of air flows will occur. And to do this without the necessary units will not work. But this system will not cope with burning and fumes when cooking food. Because in this design, metabolic processes occur naturally.
In the kitchen, the unit should be placed where the streams of unpleasant odors most often accumulate. Many install them over a gas stove. You will have to purchase a unit that has an air duct for exhaust.
What suits the kitchen?
Air injection can occur using several types. They share:
- Fit.
- The material from which they are made.
- According to external indicators.
Therefore, before you go shopping, you should decide for yourself what exactly is required. The intensity of cooking, the peculiarities of the kitchen itself, etc. are taken into account. It should be understood at least in theory that each of the forms carries in itself.
Duct shape
Here there is a bias towards the section. The stores have the following options:
- Rectangular. They can be placed anywhere, even behind furniture. They are sold as separate designs with adapters. Such an addition seamlessly allows you to lay out a passage for air flows in the ventilation shaft. At the same time, the dimensions of the kitchen themselves do not affect the unit. External data is quite acceptable, so do notbe sure to mount the structure behind the cabinets. But the performance is not too high.
- Round shape. In terms of dimensions, they are large in size, so this model will not be appropriate for everyone. Sometimes, in order to connect a part to the main hood, you have to purchase an adapter from a round section. So before buying it is worth considering every moment.
- Oval shape. Here the main advantage is in rounded shapes. Therefore, the decision remains with the owner.
Flat designs are often chosen for their compactness. The design can be carefully removed from the eyes. There are some models in stores:
- 110 by 55 millimeters. This is the minimum load and the ability to remove air flows from a room up to 300 cubic meters per hour.
- 120 by 30 millimeters. Here it is already possible to expel a large amount of air, but not more than 350 cubic meters per hour.
- 206 by 60 millimeters. This is the maximum size. Such structures are already installed in large enterprises, when it is necessary to distill large air flows.
It turns out that you need to choose the right duct for the exhaust. When a decision has been made about what functions the unit should perform, it is worth considering what material it is best suited for.
Materials
To create a good design, you can use a variety of materials. Here's what a kitchen exhaust duct might look like:
- Plastic.
- Aluminum.
- Steel.
Plastic
This material is by far the most common and frequently encountered. The available section is round and rectangular. The first plastic ducts for kitchen hoods make installation quick and easy. But rectangular ones look better externally. Here are the main pros of plastic hood ducts that make reviews stand out:
- The inside is completely smooth, which allows dirt and grease not to linger. It is this unit that will be most useful for every kitchen.
- Plastic doesn't rust - that's a big plus.
- Light weight, so everyone can mount the structure.
- In the assembly of a plastic duct for a kitchen hood, different adapters are used. This means that everyone will be able to assemble a structure of any size.
- The plastic exhaust duct does not create noise during operation. This is a big plus for a high-rise building.
- Low cost.
Cons
It is clear that with any pluses, there are also small minuses. Things to know:
- To assemble the structure, you will need a lot of additional parts and adapters. This increases the cost of the final result.
- React to heat. And when heated, they can release chemical vapors into the air, this is not suitable for people.
Aluminum aggregates
This material is often used, for its reliability. Corrugated pipes are made from it. Reviews say thatsuch designs have their positive aspects:
- The material is universal and is used in many directions. The result is a structure that is light and easy to install.
- Responds calmly to heat.
- Small price.
When there are many pluses, this does not mean that the minuses are completely excluded:
- According to external data, few people are satisfied with such pipes. Therefore, most often they are removed in specially mounted boxes or installed in a cabinet. Such conditions are not suitable for everyone, but otherwise it turns out ugly.
- During physical impact, holes appear. Deformation is often observed. Care must be taken to install.
- Aluminum is considered a heat conducting metal. As a result, condensation forms in the kitchen because of this, and this contributes to the development of mold.
Having such information, a person must decide for himself whether such an air duct is suitable for him or not. Since to create boxes you will need a place in the kitchen, and there is always not enough of it. In addition, do not forget that the condensate must be removed. Otherwise, the formation of mold and fungus is not excluded.
Steel material
The most commonly used galvanized or stainless steel. This material brings more effect. In the kitchen, air ducts are made of galvanized steel. According to statistics, people are less and less acquiring aggregates from such a composition. Although there are enough advantages:
- Big plus in a flat surface. As a result, any air flows pass quickly. Always in the kitchenthere is grease, soot and other contaminants. They don't stay on the walls. At the same time, the air flow rate does not decrease during operation.
- When heated, there is no deformation and destruction. At the same time, nothing harmful is released into the environment.
- This is an inexpensive option for people with average incomes.
At the same time, reviews note the following disadvantages:
- Compared with plastic, the weight of the steel structure will be large, which means that during installation it will be necessary to build high-quality support.
- In order for the sealing to become maximum and reliable, you will have to use additional mixtures. They are applied to each seam.
- When you have to assemble non-standard air ducts, you need to cut pipes, and this is additional equipment during installation.
- Because it is metal, it may make noise when the hood is running.
The service life of such pipes is high, so sometimes, spending a little more time on installation, you can get a reliable design. Some believe that when the steel is boxed, the noise begins to be dampened. This is already a big plus. In any case, the decision is made by a person based on their personal desires and financial capabilities.
These are the main materials from which air ducts for kitchen hoods are made. These models are always on sale. It is clear that before you purchase any of the options, you need to think through the entire design. Because not every kitchen can accommodate a box.
What is the external data of the machine?
It is clear that a hood without an air duct in the kitchen cannot exist. The configuration can be any. One of the popular options is flexible designs. This is a corrugated pipe, aluminum, but today they have already learned how to make such structures from plastic. The big advantage is that they can easily take any shape and go around every corner. If necessary, the structure can stretch or shrink. But when the pipe is not strongly stretched, the air passes slowly. This means that the work in general is not effective. A corrugated pipe is not suitable for an air duct that is more than three meters long. The fact is that due to the design features, each additional meter reduces work efficiency by more than five percent.
Rigid options are made from hard material. Assembly is simplified. The inner surface is smooth, which means that there is no collection of dirt, grease and other deposits. And this is the main plus in the operation of the unit in the kitchen. Therefore, for such an exhaust duct, the price is slightly higher than for a flexible design (265 rubles per meter versus 180). When a person begins to use a rigid structure, the benefits are immediately noticeable. The fact is that a common problem with any hood is clogging. With a rigid duct, clogging is minimal.
How to install?
When the choice is made and the design is purchased, it is worth considering every centimeter to create the right unit. The very first thing is to decide what size the duct will be. In order for the unit to be completed in compliance with all the rules and work to the maximum, you need to follow simplerecommendations:
- An outlet is being made, with a certain size. It is necessary to create such a section, as in the unit itself, in order to completely eliminate large differences. If you select less, then the motor is overloaded. There is noise and the work itself becomes inefficient.
- When the outlet does not match the main section, there are adapters to create the most comfortable conditions.
These are small installation features that should be observed. The installation itself is not as complicated as it might seem at first glance. So everyone can do it themselves. It is only important not to violate the rules and recommendations for installation.
What is worth knowing?
When work is underway to install an exhaust duct, you need to know some of the nuances:
- If possible, make as few turns as possible throughout the structure. Because each such element makes the work less efficient and correct. The hood should have no more than two or three elbows.
- It has already been noted that the hood should be cleaned periodically. Air duct - including (regardless of what it is made of). It is advisable to make it collapsible.
- If the choice is made in favor of a corrugated aluminum pipe, then it can be fixed with an ordinary clamp of the appropriate diameter.
- During installation, it is not recommended to attach the air duct to the ventilation grill tightly. The fact is, if the system is turned off, then there will be no air flow. To suchto avoid, you will have to supplement the design with a grate with small slots and a backdraft valve.
- The valve must match the diameter of the exhaust duct. Otherwise, the work will be disrupted due to the use of an adapter. This should not be forgotten during the purchase process.
- It is believed that a flat exhaust duct is the most accurate and will not spoil the existing interior in the room.
When some installation features are known, it will definitely not be difficult to install the entire structure. But before you create good conditions in the kitchen, you need to know how the structure is hidden from view.
How to hide the design correctly?
In order not to spoil the view in the kitchen, it is better to remove the air duct into the box. There are simple methods for this:
- If there is a suspended ceiling, then all pipes go well there.
- You can create a special box. It can be any color and shape. Sometimes a backlight is built into it, creating a new original element in the interior.
- Sometimes pipes run inside the cabinet.
Conclusion
Creating a kitchen exhaust system is easy. There are many offers on the market, different in price and manufacturers. It remains only to choose the appropriate design, taking into account personal desires.
