Extract without vent to ventilation: photos, reviews

Ventilation systems differ in a variety of characteristics, including technical characteristics, design features and optional filling. At the same time, the main factor determining the effectiveness of such systems is the scheme for the extraction of exhaust air, and in some cases for the inflow. The most powerful and efficient design can not properly provide air exchange, if initially there were miscalculations in the configuration of its placement. A rather unusual solution for many is the use of a hood without vent to the ventilation, the photo of which is presented below. However, it is in terms of efficiency that this option may be best under certain operating conditions of the system.

Features of the no-return configuration

Although the lack of direct access of the ventilation shaft to the street air seems unusual, this principle of operation is very common. To understand it, one should answer the question about how the hoods are called without ventilation for ventilation in the language of specialists? They are called recirculators - a common class of equipment, the action of which is based on the intake of exhaust air and its return in a purified form. That is, if a conventional ventilation system updates the air environment due to street flows, in this case the refreshing effect is provided by the operation of the filters installed in the same exhaust.

Combined models

Still, not all the housewives are ready to completely abandon the influx of clean air and complete removal of kitchen fumes. Since both systems have their own unique advantages, some manufacturers are developing hybrid models that support both functions. But here there is one nuance. The fact is that one of the main advantages that hoods have in the kitchen without venting into ventilation is a simplified installation. In the case of combined plants, it will not be possible to do less. On the other hand, the user can rely on the operation of the hood in different modes - both in the recirculation format and as a full air vent. And here it is important to note one more nuance of the operation of the flow hood. This mode of operation is not compatible with gas equipment. In the process of its operation, it is possible to form a return draft in the duct, and then there is a risk of poisoning the tenants.

Installing the hood without venting into ventilation

Advantage in the process of mounting is due to the fact that the internal part of the communication installation is practically absent. From the artist, you only need to install an exhaust system in the ceiling or wall surface and, if necessary, perform the appropriate settings for the operating mode. The installation of an embedded type is more difficult. Users appreciate them for compactness of placement and stylish appearance, but during installation such constructions require additional integration of the hinged box. In addition, the hood without a tap into the ventilation of the built-in type can be adjusted by the air intake area. Popular and a variety of models designed for installation in the countertop. The advantages of such systems include instantaneous collection of waste fumes directly on the working area, and to shortcomings - a reduction in the functional space.

Positive feedback on recirculation hoods

Although users do not always notice the merits of the work of such models in the form of cleaning ability, this factor is the most attractive. The fact is that the filtration system provides multi-stage processing of contaminated masses and the arrival of purified air. That is, in the case of the use of quality equipment, the efficiency of updating the air environment in the kitchen will be ensured. As for the visual advantages, almost all owners emphasize the lack of noise in comparison with traditional systems. Since the hood without venting into the ventilation does not involve interaction with the shafts through which air flows circulate, the absence of vibrations, hum and other noise effects is quite understandable. Already noted and the advantages of installation. From the user's point of view, this means reducing the financial costs of installation, maintaining free space for other communications, and eliminating the need for regular maintenance of the mine.

Negative feedback

Most of the negative feedback refers to the poor performance of filtration systems. The advantage in the form of purification of the exhaust air takes place only in the case of the use of qualitative membrane devices with carbon sorbents. By the way, regular replacement of filters is a separate inconvenience, which users mark. Therefore, the lack of guarantee for high-quality air purification by the technique itself is the main drawback for which the hoods are criticized without venting into ventilation. Reviews also note the high cost of such installations. Again, the implementation of the technical feasibility of cleaning makes the construction more complicated, which leads to higher prices. However, in this segment you can find good budget solutions.

How to choose the best option?

First of all, it is necessary to rely on the needs of the kitchen or other serviced premises in the volumes of air that must replace the waste mass. By the way, recycling models in this plan are easier to choose, since they perform the optimal updating of the environment - the user only needs to determine the time period during which the complete disposal of fumes and odors will occur. The most productive models are designed for installation in public places. For example, a hood without a vent to the ventilation for a cafe can have an umbrella width of 120 cm. In installations for household needs, this parameter is 60-90 cm, which is enough for efficient processing of air in conditions of medium-sized kitchen. Also it is necessary to think over the equipment with electronic systems. In this aspect, recirculation modifications are once again leading, in which the setting of operating parameters over time intervals and remote control are more often provided.

Opinions about manufacturers

Hoods of this type are found in the lines of almost all manufacturers of kitchen appliances and ventilation systems. The most favorable reviews refer to the products of such brands as Siemens, Bosch, Mile and Kaiser. In terms of combining the convenience of management and productivity, German models are the best at all. But they are also the most expensive. If you need a budget option or a model from the middle price segment, then a good solution can be a hood without vent to the ventilation from the company "Electrolux". Models of this brand are highly appreciated by specialists for the combination of functionality and reliability in the process of operation. In the same row, you can put some modifications from the model lines of the brands "Burning" and "Ariston".

Nuances of the exploitation of non-draw extracts

From the point of view of operation, models that do not involve connection to the main ventilation ducts are a bit more troublesome. If traditional systems are largely designed for passive use, then the functional elements of the non-mobile devices face the user, who must replace the filters and maintain the operability of other components of the system. In addition, the hood without vent to the ventilation can provide for not only the renewal of the indoor air, but also the introduction of useful elements into the outgoing streams. For example, it can be a purification combined with processing by means of ionization. Such opportunities should also be envisaged during the acquisition of filters.

Conclusion

Simplification of communication support is one of the principles that many modern manufacturers are guided by. An ordinary user tries to minimize the amount of equipment in the house, so household appliances become more compact, multifunctional and at the same time does not lose to traditional analogues in terms of productivity. A confirmation of this trend was the spread of the hood without vent to ventilation as a more modern and technological system. The user of such equipment can expect to get rid of the need to lay special mines, which saves money. On the other hand, manufacturers of recirculating equipment offer customers a concept in which a standard and efficient scheme for air removal to the street is replaced by machinery. That is, the air quality assurance falls entirely on the filtration system. In this approach, there are not only advantages, but also disadvantages, which are often manifested in cheap models of kitchen hoods.
