Exhaust fan for the kitchen: principle of operation, rating of the best, installation

The fumes that occur in the kitchen dur­ing cook­ing, the smell of food, soot, and con­den­sate not only set­tle on fur­ni­ture and kitchen uten­sils, but are also unpleas­ant for breath­ing and unhealthy. There­fore, if you want to make your pres­ence in the kitchen more com­fort­able and harm­less, installing an exhaust fan is essen­tial here.

Purpose and principle of operation of the device

The exhaust fan pro­vides air exchange in the room. It absorbs unpleas­ant and weight­ed air, and emits already puri­fied and fresh.

Each apart­ment has holes in the wall that lead to the house­’s com­mon ven­ti­la­tion duct. But over time, such air vents become clogged, their pow­er weak­ens, so the process of absorp­tion of for­eign par­ti­cles in the air slows down. The exhaust fan improves the air exchange process.

The fan for the kitchen is a com­pact device with blades. The oper­a­tion of the device is car­ried out after con­nect­ing to the mains. Start­ing to rotate active­ly, the blades draw in the “exhaust­ed” air in the kitchen, push it through the device and push it out. The sys­tem of many mod­els of fans pre­vents the return of such air thanks to a spe­cial valve.

Types of exhaust fans for the kitchen

Almost all mod­els of exhaust fans that are on sale have a sim­i­lar con­fig­u­ra­tion, rep­re­sent­ed by a rotor and blades. And yet there are some dif­fer­ences.

Varieties of fans by type of rotor and blades

There are the fol­low­ing types of devices:

• Axi­al or axi­al. The blades with this design are locat­ed around the axis, along its cir­cum­fer­ence they rotate. Such mod­els of fans have the sim­plest device and are most com­mon in hous­es and apart­ments.
• Cen­trifu­gal or radi­al. The dif­fer­ence between such fans is that the blades on the rotor are arranged in a spi­ral. This con­tributes to the cap­ture of air along the tra­jec­to­ry cor­re­spond­ing to the blades, which sig­nif­i­cant­ly increas­es the pow­er of such devices. That is why radi­al exhaust fans are used in indus­tri­al kitchens.
• Diame­tral (the sec­ond name is “Squir­rel Cage”). This type of fan is char­ac­ter­ized by an elon­gat­ed cylin­dri­cal shape, and its walls are long blades bent inward. The process of work lies in the fact that, while rotat­ing, the rotor helps the blades to cap­ture air and push it deep into the ven­ti­la­tion duct. This type of exhaust fan is used for pro­fes­sion­al kitchens.

Varieties of fans at the place of installation

Accord­ing to this cri­te­ri­on, there are:

• Win­dow fans. Such devices are mount­ed direct­ly into a small win­dow slot, which is cut out inde­pen­dent­ly. All fumes from the cook­ing process are vent­ed direct­ly to the out­side.
• Wall. These types of kitchen fans can be installed both on the inside and on the out­side wall (that is, on the wall with a win­dow). In the first case, the weight­ed air will be led to the ven­ti­la­tion shaft, and in the sec­ond case, to the street.
• Ceil­ing. As a rule, such fans are built into a false ceil­ing, since in the space between the ceil­ing plate and the canopy they lead a pas­sage into the ven­ti­la­tion duct.

There is anoth­er type of kitchen fans, which is pre­sent­ed in the form of a chan­de­lier. The work of the blades is car­ried out in a cir­cle, there­by accel­er­at­ing the air. Of course, such fans do not have high pow­er, so it is advis­able to use them in the din­ing room or above the din­ing area. Their use is more focused on the aes­thet­ics of the room.

Instrument selection criteria

A respon­si­ble approach to choos­ing an air-puri­fy­ing device for the kitchen guar­an­tees a com­fort­able stay in the kitchen dur­ing its oper­a­tion. When choos­ing an exhaust fan, you should pay atten­tion to:

Fan power

This para­me­ter is tak­en into account based on the area of ​​u200bu200bthe kitchen. The larg­er the room, the high­er the per­for­mance of the device should be. And vice ver­sa — for a small kitchen, a low fan pow­er will be enough.

In order to accu­rate­ly cal­cu­late the device per­for­mance required for your kitchen, use a spe­cial for­mu­la: the vol­ume of the kitchen (exclud­ing the fur­ni­ture locat­ed in it) is mul­ti­plied by a fac­tor of 10.

Fan design according to installation

In oth­er words, if it is meant to embed an exhaust device into a wall or an exhaust duct in a wall, then you need to pur­chase a mod­el for wall mount­ing. Sim­i­lar­ly: for instal­la­tion on the ceil­ing — a fan for ceil­ing instal­la­tion, for win­dow instal­la­tion — the cor­re­spond­ing mod­el.

noise effect

The oper­a­tion of the fan is accom­pa­nied by the pub­li­ca­tion of char­ac­ter­is­tic nois­es, and this should be tak­en into account. It is rec­om­mend­ed not to take mod­els that emit a sound inten­si­ty of more than 40 deci­bels. Accord­ing­ly, the low­er the noise fig­ure, the less notice­able the exhaust fan will be dur­ing oper­a­tion.

The presence of a check valve

This cri­te­ri­on should be tak­en into account when it comes to choos­ing a wall or win­dow fan. The pres­ence of a valve will help pre­vent the pen­e­tra­tion of for­eign odors from the ven­ti­la­tion duct or the street.

Resistant to high moisture and temperature changes

These cri­te­ria are rel­e­vant for a kitchen fan, since tem­per­a­ture changes and con­den­sa­tion con­stant­ly occur in the kitchen.

Fan dimensions

The pur­chased device must not only fit per­fect­ly into the place of its instal­la­tion, but also close the bor­ders of the old frame from the ven­ti­la­tion duct.

Control type

Accord­ing to this cri­te­ri­on, fans with auto­mat­ic con­trol and mechan­i­cal con­trol are dis­tin­guished.

The first option is the most con­ve­nient. It is equipped with motion sen­sors, tem­per­a­ture and humid­i­ty change sen­sors, and depend­ing on the indi­ca­tors of these para­me­ters, it changes the inten­si­ty of its work or turns off com­plete­ly. Con­trolled with a remote con­trol.

The sec­ond type — turn­ing on / off the fan is car­ried out using the pow­er cord or using a sep­a­rate switch.

Design

The appear­ance of the exhaust fan should fit into the over­all inte­ri­or of the kitchen.

The best models of exhaust fans for the kitchen

Exhaust fans dif­fer in many para­me­ters, includ­ing cost. In the mat­ter of choice, it is of no small impor­tance, besides, among the bud­get options you can find quite wor­thy exhaust fans.

Next, sev­er­al mod­els of pop­u­lar exhaust fans will be pre­sent­ed. Their mer­its are appre­ci­at­ed by many buy­ers whose reviews rec­om­mend them for pur­chase.

Installing a fan in the kitchen: step by step instructions, tips

Instal­la­tion of win­dow and wall fans dif­fer from each oth­er. The first option is eas­i­er to install, regard­less of weath­er con­di­tions and repairs in the apart­ment. But the wall-mount­ed device will have to be com­bined with the gen­er­al alter­ation of the room, as well as pro­vide for a few more nuances.

Mounting a window-type fan

Step by step guide:

1. As a rule, in typ­i­cal apart­ments, the kitchen room is equipped with one win­dow. If there are sev­er­al of them, then you need to build in the fan in what is locat­ed clos­er to the cook­ing zone — to the stove.
2. The height for embed­ding is cho­sen as high as pos­si­ble, but so that at least 20 cm remain to the edge of the win­dow glass.
3. The para­me­ters of the fan are mea­sured (length and width), with­out vio­lat­ing the bound­aries of the cas­ing, and accord­ing to the mea­sure­ments, a con­nec­tor is cut out in the win­dow glass with a glass cut­ter.
4. Rub­ber tabs are installed on the fan cas­ing, which will help to bet­ter fix the device on the win­dow. After that, the fan is placed in the pre­pared slot.
5. A rotor with blades is placed in the cas­ing so that the edges of the lat­ter do not touch the walls.
6. After these manip­u­la­tions, the fan is con­nect­ed to the mains and the cor­rect instal­la­tion is checked. If every­thing works, then pro­ceed to install the pro­tec­tive grille.

Installation of a wall-mounted exhaust fan

The instal­la­tion steps described below are suit­able for installing the fan on both the out­side and the out­side (win­dow) wall. The only dif­fer­ence is that when installing a fan on an out­er wall, it is cov­ered with grilles not only inside the room, but also out­side.

Step by step guide:

1. Before installing the wall-mount­ed kitchen fan, you need to pre­pare the ven­ti­la­tion duct. If nec­es­sary, it is cleaned. If the house has just been com­mis­sioned, this may not be required.
2. Most often, the ven­ti­la­tion duct has an exit to the kitchen in the form of a hole closed with a grate. It needs to be removed. If the hole in the wall is not suit­able for installing a fan, it must be enlarged. To do this, use a ham­mer drill for con­crete.
3. After that, a small piece of pipe is installed in the hole, and then the ven­ti­la­tion device itself.
4. At the end of the instal­la­tion, check the oper­a­tion of the device by con­nect­ing it to the pow­er sup­ply. If every­thing works prop­er­ly, then install a pro­tec­tive sur­face grille.

An exhaust fan for the kitchen is a nec­es­sary device, espe­cial­ly if the kitchen is small and the instal­la­tion of an extrac­tor hood in it is inap­pro­pri­ate or an addi­tion to the installed hood is nec­es­sary. The fan will make your stay in the kitchen more com­fort­able, as it will absorb all the fumes and odors, and release fresh and pleas­ant air.
