Vent diffuser - types and purpose

Cozy and warm home is the key to excellent well-being. And often some little things can make it unusual and unique and unusual. These include diffusers for ventilation systems, although they are not considered primary elements.

If you want to learn more about them and use them properly for their intended purpose, we recommend reading the article to the end.

So what is a diffuser in ventilation? So called air distribution devices designed to supply air into the room and its withdrawal from it. In addition to ventilation systems, it is used in heating and air conditioning.

Classification

In form

The information below will give you the opportunity to understand what you need to pay attention to when choosing diffusers. You will understand them taking into account the expediency of installation, specific features and needs of the ventilation system.

There are two options for models of this device:

• a circle;
• rectangle (square).

Tip: Many designers prefer to use circular diffusers in the interior, which resemble lamp shades, which allows them to be successfully combined in the design of rooms.

Modern market can offer interesting models of round shape:

• fan diffuser, in which the air flow valve is built in and there are special clamps for installation on the ceiling;
• dish-shaped, although designers rarely use them;
• slotted - used in order to achieve the desired direction of the air flow. Due to their shape, it is possible to change its exit angle. Such models are distinguished by compact dimensions of the installation boxes, which makes it possible to make the ventilation openings for the supply and outflow of air almost imperceptible. Installation of slot diffusers is done by hand with the help of brackets, even in confined spaces, for example, behind a suspended ceiling.

Which one to buy depends on taste and design intent. But remember, in creating coziness and comfort there are no trifles.

To destination

Now consider the practical side of the issue, which is much more important. Devices can be:

Extra options:

1. Diffusers can also be unregulated and adjustable. In the latter there are blinds that can change the volume of the air flow and its direction.
2. Make devices from:

• metals (aluminum or steel), which are more reliable, durable and have a long service life. In addition, they are considered to be optimal from the point of view of design, and also have "anti-vandal" characteristics. The price of such diffusers is somewhat higher than plastic;
• plastic - the device does not rot and does not rust. Have a small weight and a large number of color variations.

Air distribution

To create a selected indoor microclimate, it is necessary to get rid of noise and drafts, which most often irritate customers. Just diffusers are a good engineering solution that will help to efficiently distribute the air flow through the building. Devices reduce air velocity during its passage through flexible ducts and, conversely, increase it when air enters the exhaust duct.

In addition, you will have the opportunity to exercise control over these processes. This will help to add comfort to the room in which the exhaust ventilation pipe is located.

Most often, swirl diffusers are installed on the ceiling or on the wall, which are a decorative panel of a rectangular or round shape, sealed along the contour with a special gasket. If it is ventilation, there is an air guide ring and impeller on its back side, the latter is not provided for exhaust.

The front panel of the diffuser is attached with screws to the cross member of the wiring box. Installation of the device occurs through the holes on the flange or brackets. The front panel of a conventional ceiling diffuser is a frame in the center of which a profiled plate is placed.

Today, the industry offers different models that allow directing the supply or exhaust air in four directions, and not just in one. There are also special models of diffusers designed for work in rooms with high humidity and in aggressive environments. For example, the instruction allows them to be used in swimming pools or production workshops.

Tip: the correct installation of diffusers allows you to get good ventilation with minimal temperature change, which is especially important when saving heat in the room.

Conclusion

With the help of diffusers, it is possible to provide not only the direction and volume of air flow, but also its outflow. In this case, there is a correct distribution of air masses throughout the building or a specific room, with minimal heat loss.

The industry offers models made of different materials and different colors, so when choosing, you should pay attention to the technical characteristics of the devices.
