The choice of corrugated tubes for hoods

The ventilation system is needed not only in industrial buildings, but also in ordinary houses and apartments. Hood unit in the kitchen, it ensures removal of burning and strong smells so that they do not settle on the walls and ceiling. Such a necessary ventilation system should not be neglected by any housewife who cares about the health of her family. To work hood, it must be connected to the vent. The best air vent today is a corrugated pipe for exhaust. It bends in all directions, without forming sharp turns, so it is convenient to use it even in the most inaccessible places.

Benefits of using

The air vent can be either corrugated or smooth. Despite the fact that in terms of physics,a smooth surface is better to facilitate the smooth passage of air through the pipe than corrugated, the latter uses a wider application. Especially it concerns aluminum pipes. Their undeniable advantages over other species are:

• low weight;
• flexibility;
• heat resistance;
• corrosion resistance;
• sufficient length;
• resistance to aggressive media;
• ease of installation.

But the main advantage of aluminum corrugated pipes lies in their ability to run in any trajectory without sharp bends. With their installation the owner can handle by myself, because he does not have to install a complex system of fittings on the corrugation to bring it to the outlet.

Aluminum pipes have only one limitation: due to insufficient heat resistance they are not recommended to be installed on boilers, furnaces in which solid fuel is burned. Metal can not withstand very high temperatures.

Useful tips for choosing

Very often a corrugated pipe for a hood comes with it in a set. That is, it will not be necessary to look for a corrugation that matches the diameter later. But such a standard set is not suitable in every case.Not everyone has the same arrangement of ventilation holes relative to gas or electric stoves. Therefore, it is best to fit the exhaust pipe separately, after the installation location has been determined.

In order not to be mistaken with the choice of pipe, read carefully the instruction manual for the hood. It should contain information about the diameter of the outlet and the corresponding diameter of the pipe.

You should not worry if there is a square output instead of a round one on the hood: there are special adapters that will help you securely connect the corrugation to it.

Try to choose a pipe that is suitable for diameter to the exhaust hole, as too narrow a corrugation can significantly reduce the efficiency of the system due to the difficult passage of air. On the contrary, a too wide air vent will not affect the efficiency of the device, but only make the structure heavier. After all, the efficiency of the exhaust system depends only on its pipes (this applies to exhaust hoods with ventilation).

Do not forget that before hood installation the outlet must be grated with check valve. Thanks to the many small holes in it, natural ventilation of the room will take place, and an exhaust system can be installed in a special hole in the center. A check valve on the grille will be needed in order to include normal ventilation at the end of the hood.

Device mounting

It is important not only to choose the corrugation, but also to install it so that the efficiency of the system does not fall. This means that you need to try to position the pipe at the shortest possible distance from the vent hole without sharp bends, the presence of which will weaken the thrust by 10%.

Even if the ventilation window is located in the opposite end of the kitchen from the hood, you can stretch the corrugation under hinged ceiling. Experts also advise before choose a hood, make sure there is no return thrust from the outlet. To do this, conduct a small test: attach a sheet of paper to it, if it sticks and hangs itself, then it makes sense to install an exhaust system.

Before installing the corrugation for the hood must be stretched to its full length. Otherwise, the air can make noise inside, touching the curvature.

Follow the special instructions in the instructions for the correct positioning of the hood. If you have gas stoveoptimal the distance between the hood and the burner must be at least 75 cm. For electric hob and hobs are allowed a smaller distance, about 60 cm.

Thus, to choose and install the usual corrugation for the hood will not be difficult, this task is under the power of any man.
