The best air ducts for ventilation in 2020

In order to maintain an optimal microclimate in a residential or public space, it is important to install the correct ventilation system. One of the main elements is the air duct, which is a ventilation duct that provides continuous air flow in one direction.

The editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best air ducts for ventilation in 2020.

Varieties

Air can move by various means, for example:

• Natural ventilation requires mounting holes or slots to allow fresh air to flow into the room. The use of windows is also allowed, for this you only need to open the window. In this case, the spent elements leave through the ventilation shafts.
• When the temperature is high outside, there is no effectiveness from the previous method. Then forced ventilation is used. The inflow of air masses is carried out by a fan that is installed in a convenient place.
• There is also a more perfect system: supply and exhaust. In this case, two air ducts are mounted, one is responsible for the intake of air, and the other is necessary for its removal.

They try to create an individual ventilation system in each building or room. Therefore, various air ducts are used, which differ from each other in some technical parameters.

Installation method

There are two types:

• Internal ducts, also called ventilation shafts;
• External. They are installed on buildings.

What material are they made of?

Today there are at least 4 popular materials available that define the field of application. In addition, each has a different price and durability. So most manufacturers produce models from the following materials:

• Galvanized steel. This option has good corrosion protection and is not susceptible to certain chemicals. Highly resistant to moisture. Therefore, it is suitable for installation in bathrooms, saunas, swimming pools, etc.
• Stainless steel. The product is able to withstand temperatures up to 500 degrees. Therefore, the main area of ​​use is manufacturing enterprises, for example, a stainless steel air duct is actively used in metallurgy.
• Polymer products are lightweight and have a low cost. They are practical to use, as they tolerate humid climates and alkaline environments without any problems. However, they should be used carefully, as they are unable to function at high temperatures, which is why they begin to melt. Mechanical damage can also damage the model.
• Metal-plastic. This option is a combination of metal and polymer devices. Their beautiful appearance allows them to be installed under any modern interior. Technical characteristics are no worse than galvanized steel. However, there is also a drawback - the high cost.

Sectional shape

Models are mainly sold that have a round or rectangular shape. These are the most requested options and are suitable for every occasion. Some manufacturers abandon this solution and produce elliptical air ducts, which increases efficiency.

Round air ducts are characterized by low cost, as they are easier to manufacture. In addition, this design guarantees fast air flow movement, while the noise level is minimal. Installation will take a minimum of time, and the external design is beautiful and aesthetic.

Rectangular models are distinguished by the fact that they are easy to install in any room. Even if an unusual design is used, installation does not take much effort and cost. The only drawbacks of this element are its high weight and high price. Therefore, this option is not suitable for everyone.

Differences in manufacturing technology

There are only three versions for sale:

• Straight seam. Such a structure is made of a solid metal sheet, while its length should not be less than 1.25 meters. The ends are connected by welding. The rectangular shape is characterized by the presence of an additional seam, which gives rigidity, is located on the bend.
• There is another option - spiral welded. They are made from a long overlapping metal strip that is welded together.
• Spiral-wound. In this case, a strip made of galvanized steel is used. Its width should not be less than 13 cm.

By hardness

This point should be given special attention. There are 3 varieties in total:

• Flexible. Simple products that are made of steel wire and the walls are made of foil. The main advantage of this option is simple installation and transportation. The product can be easily connected with other products, making it easy to operate. The corrugated pipe can be installed at any angle, as it bends and unbends easily. Of the shortcomings, poor sound insulation, as well as low strength characteristics, are mainly noted. In some cases, air can be trapped inside this element.
• Semi-rigid models are produced from steel or aluminum strips, the connection is made using a spiral seam. This product has good flexibility and good durability. However, such an element can be stretched only once. Therefore, this work must be done responsibly.
• Tough. These are excellent models that are made with the user's requirements in mind. They have high strength rates and good noise insulation. However, they are distinguished by their high cost and complex installation.

Optimal pipe size for duct

To calculate the required volume, you will need the help of a specialist or you should be guided by the recommendations that are present in SNiP 41-01-2003. This will allow you not to make a mistake in the calculations and buy a suitable option. In addition, the recommendations also indicate the maximum air speed: for residential premises - 1 m / s with natural ventilation, 3-5 m / s if forced ventilation is used.

Finding the right size is not difficult, as modern enterprises produce hundreds of different models. Therefore, you can easily select an air duct not only for residential premises, but also for construction sites or public buildings.

• The limiting size of a round product is up to 2 meters;
• Rectangular structures are available in the range from 10 cm to 3.2 m.

How to clean the duct?

The ventilation system will do its job well only when it is correctly installed and assembled. But we should also not forget about timely maintenance, as at times garbage can get there. It is not necessary to dismantle the device for cleaning.

• Mechanical method. This option is suitable for rigid structures, since vacuum pumps are used here, which can damage soft walls.In addition, hydromechanical tools are often used, which thoroughly remove any contamination.
• The chemical method is designed to remove traces of grease that often accumulate in kitchens and food service areas. However, only suitable formulations should be used so that the components do not corrode the outside and inside of the duct.

In addition to constant cleaning, pipes should be disinfected, since pathogenic bacteria and sometimes parasites are constantly formed inside. If they get into food, due to improper use or untimely cleaning, then the person will be poisoned. Disinfection should be carried out using powders or liquids based on hydrogen peroxide.

If a person does not have special means with which to clean the sewer, it is better to call the appropriate service. Workers always have effective devices that will clean the air duct in a short time, while doing it efficiently.
