Cooker hoods with ventilation connection: overview, principle of operation, prices. Connecting a cooker hood to ventilation

Cooker hoods with and without ventilation connections play in the kitchen not only the role of venting vapors and aromas for environmental safety purposes. They also prevent surface damage. Various fumes, fuel combustion products and residual grease in the air gradually accumulate on walls, work surfaces, ceiling and floor. Due to this effect, they begin to fade, deteriorate from fat and other deposits. Using the hood, these processes can be minimized, which will save your finances and extend the life of your kitchen equipment.

Types of flow hoods

Models and varieties of the devices in question differ in size, design, price, principle of operation. Cooker hoods with ventilation connections are used to maximize the removal of air from the space above the working kitchen surface and its subsequent deactivation into ventilation through the duct.

The considered units are divided into two types:

1. Passive models. The design does not include the installation of an electric motor. The entire working process is due to the draft of the ventilation duct system.
2. Active kitchen hoods with ventilation connections function thanks to the additional connection of electric motors, which are located inside the dome. Motors provide powerful airflow, exciting soot, soot, droplets of fat.

Arrangement

Any type of flow exhaust design is mounted directly above the stove. The unit is connected to the ventilation wells by special ducts. It can be a tin box or a metal corrugation. To avoid unwanted noise, air ducts are equipped with soundproofing material. They will not ruin the aesthetic appearance if you mask the device behind suspended ceilings.

On the neck of the main device, the air ducts are fixed with clamps. In addition to the elements considered, hoods include the following components:

• Coarse filter. It protects the devices themselves from deposits of fat and soot.
• Thin filter. Serves to remove odor. Consists, as a rule, of coal elements.

Timely replacement and cleaning of filters will not only increase the efficiency of the hood, but also extend the life of the unit itself.

Hood without duct

Such a device operates recirculating and does not require connection to ventilation ducts. Air is sucked into the filter unit with a fan, where it is cleaned of odors, burning, excess moisture and fat. The efficiency of the device depends on its power and filtering system. Cooker hoods without ventilation are equipped with two main filtering units.

The first system is used to eliminate fat in the air, and also provides rough cleaning. These elements are made of aluminum or acrylic. The first option is more effective because it lasts longer and is easy to clean.

The next system fights odors, excess moisture, and burning residues. The main element is a carbon filter. It requires regular replacement (approximately once a quarter).

Types of cooker hoods without ventilation

All the devices under consideration work on a single principle, but differ in the type of installation, namely:

1. The classic version in the form of a flat umbrella. Has no special design sophistication. It has established itself as a good cooker hood for small kitchens.
2. Hanging model. It is installed above the stove, the air flow is released from the front part, which makes it possible to mount lockers on it.
3. The built-in version. Allows you to hide the fixture inside the furniture. The device is compact and high power.
4. Cooker hoods without connection to ventilation with telescopic equipment. These varieties can be advanced closer to the work surface if necessary.

The units under consideration perform various functional tasks, depending on where they will be mounted (in the middle, in the corner or in a separate way).

Advantages and disadvantages of hoods without air ducts

Kitchen and any other equipment have their disadvantages and advantages. An exhaust device without connecting to a ventilation system has several advantages:

• Elementary installation that does not require the use of additional fittings and connecting hoses. Installing the device yourself is not difficult.
• Profitability. Considering that even kitchen hoods (60) with connection to ventilation use an order of magnitude more energy, this modification can rightly be called economically viable.
• The cost of the design in question is lower than a similar system with an air duct.

The disadvantage of such units is the need for regular replacement of filter elements. This will have to be done at least once a quarter. Cooker hoods without connecting to ventilation, the prices of which start from 5 thousand rubles, will become a reliable assistant in your kitchen.

How to connect a hood without a duct?

Devices operating in recirculation mode are easier to install than cooker hoods with ventilation. This is due to the fact that they do not require interaction with the ventilation shaft. The main thing in these devices is to change regularly filtering elements.

First you need to make sure that there is power supply near the installation site of the hood . Before mounting the unit, mark the attachment points, drill holes, install dowels or screws for subsequent fixing of the device. The next step will be to mount the hood on the wall, connect it to a power outlet and test it.

Mounting the unit with an air duct

By and large, connecting a cooker hood to ventilation will not be a special problem. The main thing is that all connections are tight and securely locked. When performing work, the following recommendations should be considered:

• The connection should not completely block the ventilation channel, so that when the device is turned off, natural air draft is carried out.
• The normal operation of the unit will ensure the passage of air flow without additional interference.
• The length of the duct and the number of curls should be minimized.
• Choosing between the corrugated and smooth surface of the pipes, it should be borne in mind that the first option bends well, but delays the flow.
• At bends, the duct should have smooth transitions.
• Additional air flow after ventilation or constant supply from the street will make the hood more efficient.
• It is forbidden to mount the device with access to the smoke channel of the gas column.

The way how to connect the hood to the ventilation yourself, is not particularly difficult, subject to certain nuances and technological subtleties.

Conclusion

Having studied the features of the device, the principle of operation, the nuances of operation and installation, we can conclude that the hood must certainly be present in the kitchen. The choice of modification depends on the size of the room, the intensity of the work process, financial capabilities and personal preferences.

Connecting the hood to ventilation, the principle of which is based on the suction of the air flow with its subsequent transportation to the ventilation shafts, is more complicated and requires certain calculations. For example, excessively long ducts will look unaesthetically and reduce the efficiency of the device itself. Subject to certain points, installation work is very simple and understandable.

The option without an air duct is much easier to install, and its price is lower. However, there are some peculiarities. Regular replacement of filter elements will be required, otherwise the efficiency of the hood will be noticeably reduced. Devices without interaction with ventilation have several types of fastening, which allows you to choose them for any size and interior of the room.
