Blunders are often allowed when installing the hood.

Currently almost every kitchen extractor fan is installed, whichremove grease particles, combustion products and high cooking odors.

And everything is good, but only It does not always work effectively hood after installation.

Often, just the opposite.

after installation, hood problems begin, such as the condensation on windows and swelter in the kitchen. On the whole, microclimate in the apartment It is changing for the worse.

Wherein often the problem is not in the hoodAnd in her improperly installed.

there is several blundersthat allowed the installation is particularly common. They are addressed and discussed below.

Often in the kitchen there are only one ventLocated near the ceiling.

Therefore, it thereto during assembly and usually fed duct.

At the same time quite often commit a blunder.

Completely cover the vent duct of the hood.

It is a mistake to believe that through the hood will still occur breathability.

The extracts normally mounted check valveThat closes when switched off and Natural ventilation is disturbed.

In this case, the air in the room is cleared Only when the power exhaust, Due to which the products of combustion and excess water simply do not appear in its entirety.

Just the presence of one of the ventilation duct combined natural ventilation and exhaustion try using special ventilation grille.

But this method of extraction duct assembly is a mistake.

• At first, Pressure is created when the drawing and the air flow is forced through the grate designed for natural ventilation back to the kitchen.
• SecondlyWhen drawing off breathability is still worseBecause the original diameter of the opening for natural ventilation was at least twice that of steel.

I think the question has matured:"How, then, to properly install the hood without deteriorating the natural ventilation?".

It's simple. One air duct should be used for extraction and for natural ventilation, but installing it tee and check valve off-axis.

Then, when you turn on the hood under air pressure check valve is closed andblock the ingress of contaminated air into the kitchen.

BUT when it is turned offOn the contrary, openand air by gravity is easy to go into the vent.
