Exhaust air vent without ventilation

The ventilation system in a modern home is a necessary element, the quality of which affects the level of comfort in the kitchen. The most common cleaning device is a kitchen hood with exhaust air outside the room. But what to do if the design with the air vent for some reason is impossible? In this case, help exhaust without removal to the ventilation.

Principle of operation

The peculiarity of this device is that, thanks to a system of multistage filters, the air becomes indoor clean, without impurities, odors, grease and soot. An exhaust hood for a kitchen without an air duct is needed if the cooking surface is far from the ventilation channel, there is no possibility to stretch the pipes,general cleaning system is not functioning or it is impossible to install the structure due to high ceilings.

In general, according to the principle of operation of the kitchen hood, there are two types: with air exhaust (flow) and without duct (recycling).

In the first case, the circuit for removing the polluted air is constructed in such a way that it is directed along ventilation duct into the air duct outside the room. If functioning properly, the productive design provides air exchange. If mistakes in placement or configuration are made, the device will not cope with its task.

Constructions such as recycling hoods for the kitchen without exhaust air to the outside. This class of equipment uses recirculation in its electrical circuit: a motor drives a fan that drives away polluted air, a mixture of food residues after two filter (fat and coal), returning it in a purified form. This type of design does not require air to enter the room. To operate the equipment, it is enough to turn on the power plug.

Since both cleaning systems have their advantages, there are also hybrid models. Combined models support both functions. However, in this case, the installation will be difficult.

Important! Combined operation mode is not recommended to be combined with gas equipment, as there may be a return thrust in the air vent, and there may be a risk of carbon monoxide poisoning by users of equipment.

Below we consider what are the types of hoods for the kitchen without an air duct.

The main types of cleaning systems without duct

Due to the fact that the hood is equipped with a complex of filters, the device is also called filtration. Purification systems are two-tier.

1. The first level models include acrylic cleaners. The main component is acrylic filter - designed for single use. After some time (3-6 months) it needs to be replaced. The first level cleaners include and metal filters. They are more beneficial in terms of operation - just wash with water in a soapy solution.
2. By the second level cleaners include coal filters. Due to the absorbing properties of coal, filtration systems clean the air perfectly. Disadvantages circulation hood for the kitchen without an air duct, it is considered that the carbon filter is only available in a one-time version, so the user needs to regularly change this important component. There are many common misconceptions about hoods with carbon filters - read about them in our article.

According to the shape of the body electric hoods are:

1. Horizontal. The flat design is positioned so that the hob is parallel.
2. Vertical. This type of filtering system is used in spacious rooms. In this case, the structural elements are located vertically with respect to the plate.
3. Inclined. This type of device is not often found in the filtration variant. Inclined hood over the stove work silently, perfectly save space, having an effective performance.

Inclined hood

By type of installation:

1. Embedded. They are masked inside kitchen cabinets.
2. Suspended. They are mounted on the wall, the design may contain a hinged panel to expand the zone of capture of the dome.
3. Island. If the stove is located at some distance from the walls, use such ventilation equipment.

Advantages and disadvantages

The main advantages include:

• multi-stage filtration of polluted air masses, after which the air returns purified;
• hood without duct does not emit strong noise, vibration;
• appropriate use of space for other communications due to the preservation of free space;
• reduction of financial costs for the installation and installation of the air outlet;
• compact version of the device will fit perfectly into small room;
• the filtration device allows you to save the temperature in the kitchen - there are no open windows, windows and doors;
• the device allows you to save electricity;
• possibility of air purification with additional ionization;
• eliminates the need for maintenance of the ventilation system.

However, along with clear advantages, drawbacks to the kitchen without an air duct also have disadvantages. The main disadvantages of this device include:

• regular replacement of filters;
• high cost of equipment.

Also, many users note that the filtration system does not always cope with the purification of exhaust air.Only owners of an expensive membrane device with carbon filters were positive.

Selection of filtration hood

When choosing a circulation technique, pay attention to the following important points.

1. Dimensions of construction. The cleaning appliance must not be smaller than the size of the hob or hob. Ideally, the dome is more than 10 cm.
2. Performance or power. If this criterion is higher, then the hood will clean more air in 1 hour (normally the air changes 12 times). To determine this indicator, multiply the area of ​​the room by height and by 12. With an area of ​​12 squares, the height of the kitchen is about 3 m, the required capacity is 12 x 3 x 12 = 432 cubic meters / hour. This figure is the minimum performance of the device, it is recommended to increase it by at least 30%.
3. Opportunity backlight for ease of use hob.
4. Which one filter used in cleaning equipment.
5. Possibility of change speeds air pulling.
6. Additional functions (built-in timer, electronic display, instrument status indicator, and others).

Hood with light

Extraction without ventilation communication support. A common air purification channel in a house does not always cope with its tasks. This is one of the important criteria that manufacturers take into account when developing a filtration system. Modern kitchen appliances should not only be attractive in appearance, functional, compact, but also not lose in the basic performance indicators of traditional appliances. This fact confirms the tendency to opt for an exhaust hood for the kitchen without diverting to the ventilation system, as more high-tech and innovative equipment. However, consider all the subtleties of this system, so that the equipment served for a long time and without failures.
