Fan for exhaust: exhaust ventilation in the kitchen

Kitchen exhaust fans to help get the job done air ducts and ventilation in the room more efficient. Rather than arrange uncontrollable draft, opening the doors and windows in the kitchen, it is best to choose the appropriate technique for forced ventilation. Especially because of its relatively low cost.

The importance of good ventilation

In the kitchen, in addition not very pleasant smell and the air can be filled with gas products of combustion and excess moisture. As a result, the walls are covered with patina or suffer from a drop-down condensate.

At impossibility of the regular airing the only way to maintain a healthy atmosphere in the room is the kitchen installation of the fan for exhaust.

However, the performance of such equipment should be carefully selected. Fan power shortage will not allow to maintain standards of ventilation, and too much of its stock will lead to a negative pressure air and noticeable drafts. Performance exhaust should match the size of the kitchen, otherwise it will be a waste of money.

types of fans

canal

This ventilation is mounted directly in the ductwork. This setting is hidden from the eyes of a simple bill bars, but it works very effectively. On the other hand, the channel fan is not suitable for each mine.

Wall

It is much easier to find appropriate wall structures for standard circular and rectangular openings. Bathroom waterproof models are available, as well as systems equipped with moisture sensors. But the kitchen fans to exhaust enough to have automatic, self-controlled power. This will allow the rational use of electricity and prolong the life of equipment.

Window

Now rarely used windows model. But if you are going to replace the old kitchen window at the modern windows, you can order the production of the frame, taking into account the fan unit built, or embed it directly into the glass. The unit will draw exhaust air from indoors to outdoors, but without a check valve in the winter it becomes a source of severe drafts.

basic design

Domestic fan with flap overlapping the reverse flow of air from a common shaft, perfect for high-rise multi-family. This design does not allow the exhaust air from the lower apartments enter into your kitchen, when the system is turned off.

exhaust fans in the kitchen It can be divided into three types:

1. The kitchen is traditionally mounted axial (axial) fan. They are quite compact, easy to install, and their power is enough for home use.
2. Centrifugal (radial) are used only in the production due to its slimmer design.
3. Flow fan for hoods. Their main applications - large kitchen large cafes and restaurants where many furnaces running at the same time.

selection rules

Performance

According to the construction and sanitary norms and exhaust system in a separate kitchen should provide 10, and combined with living quarters - 12 times the replacement of the entire volume of air. That is more than cubic capacity of the room is 10-12 times. Add to this 30% of the performance reserve, and you will get the required power of the fan for drawing it in your kitchen.

Low-power models can be taken only in the case if you just need a little help of the existing ventilation. On the contrary, in poor traction in the shaft in the calculation of the required capacity will have to lay the air renewal rate at 15.

Noise level

In terms of noise is best to set the fan which does not cross the threshold of 35 dB - is little more than a whisper human (30 dB).

Engine power from such equipment must not exceed 36 watts. The kitchen, which is part of the living area apartments, it is appropriate to put a low-speed fan that produces virtually no noise.

terms of Use

Since the kitchen air is heated strongly enough, the fan should be adapted for operation in hot environments. Especially if it is installed above the stove. For normal operation it manufacturers cover the working surfaces of their units with heat-resistant films and structures. Without them, the fan, of course, not oplavitsya but can exude an unpleasant smell of burnt plastic.

Additional functions

Some models of modern fans for drawing simple not name. Manufacturers in the pursuit of customer equip them with a wide variety of additional options:

• filter mesh-grease;
• human presence sensors;
• humidity controllers;
• programmable timers.

Do you need these features in a simple fan - up to you, but any additions to the cost of electrical equipment and reduces the life of trouble-free operation.

Mounting

installing exhaust Fan Kitchen engaged master installers of electrical equipment. But a low-power device is quite able to install and own, if you know some of the nuances:

• To extractor working as efficiently as possible, the air inlet should be as high as possible on the ceiling.
• To combine a round axial fan housing with a rectangular opening in the duct will have to buy an adapter if it is not attached to the unit.
• Equipment powering is more convenient from the nearest point of light, hiding the current wire in a plastic trough.

The rest of the procedure for the wall mounted fan is quite simple:

1. Ensure the correct operation of the ventilation duct.
2. The nozzle insert hole.
3. Set the air holes of the fan mechanism and lock it with a special glue or anchors.
4. Connect the unit to the power cord and check the operation.
5. Pass the cable into the groove of the mounting bar, and the mechanism of close decorative lattice.

The overall performance of any extraction technology will improve significantly if the frame to establish a compact kitchen window air inlet. In place of the removed exhaust air fan will immediately arrive fresh stream from the street.
