Ceiling diffuser: purpose, types and installation

An important part of the ventilation system of the room is the ceiling diffuser. This device serves to eliminate air from the rooms. Without it, the room will not be comfortable. If the ventilation system is hidden, the diffuser is considered to be the only part that will be visible. Therefore, it is necessary to choose a suitable device, because it should not only cope with its functions, but also be suitable for the design of the room.

Definition

Ceiling diffuser is a ventilation grill on which the ventilation duct ends . Why does it have such a name? This is due to the fact that the device not only eliminates the exhaust air, but also carries out an influx of fresh air.

Work principles

Diffusers for the house must have a shape that evenly distributes the air throughout the room. This is necessary for a comfortable environment. This is provided by:

• The shape of the holes: if there are many of them, this is ideal for uniform mixing of air.
• The use of a static pressure chamber: it serves to protect against direct air penetration.

The camera is used as a buffer, with its help clean air comes into the room at a low speed. Thanks to this people are protected from drafts, dust and other troubles. In classical apartments, there is hardly anywhere to be found a ceiling diffuser. This is due to the fact that in apartment buildings there is exhaust ventilation. Because of this, you can use the traditional grid under the ceiling.

Alternatives

Is it possible to not use diffusers for the house when the supply air duct is under the ceiling? This is possible, but only with two nuances:

• Provision of only supply ventilation. Excessive pressure is used to eliminate dirty air. This system is used in offices and commercial premises.
• It is necessary to mount suspended ceilings.

The air is pumped above the suspended ceiling. The volume under it is static pressure. In the room, it penetrates through perforations in the ceiling panels. This system affects the false ceiling. It should be cassette, rack or with metal parts. You can and do not use perforated panels and slats: to harmonize types and colors.

Materials

These parts are of different types. First of all, they are divided according to the material. The most popular are the ceiling plastic diffusers. There are polyethylene and polyvinylchloride, which have a cheap cost. They are durable, which is necessary for pumping and pumping air. A docking of parts is simple because of the plasticity of the material.

There are aluminum and steel products that are commonly used in production. Powerful fans can damage not very strong air ducts. Especially since ventilation usually works in a gassy atmosphere, as well as where there are acid fumes and heavy dust.

Ceiling diffuser can have a decorative part. Usually it is made of wood. Slot diffusers change the escape of the air outlet. They will look great in any style. A narrow crack on the ceiling will not be very noticeable.

The form

Diffusers are of the following forms:

• Round: effectively mix the air thanks to swirls. This is provided by a complex shape, a grid and blades.
• Square: they function like round ones. The room will have a decorative grille, and the static pressure chamber is hidden behind it.

Both devices are suitable for indoor use. They will be provided with the correct supply of fresh air into the room. In many rooms a standard instrument is used - a ceiling diffuser (600x600 mm).

Installation

The installation variant is determined by the type of ceiling. This is also affected by the shape of the diffuser. Round devices cut into plasterboard or mounted in a stretch ceiling.

Slot diffusers are attached to a reinforced concrete surface. They fit perfectly into any design. In its simplest form, it looks like a slot in the duct, closed by a grille. The square diffuser is placed in a cassette ceiling. Thanks to the dismountable ceiling design, you can access the duct to perform cleaning and maintenance.

Installation work involves the following:

• It is necessary to mark the place of installation.
• Then mark the fastening and its frame.
• You need to learn the installation method. The design parameters are marked.
• Bulgarians and all around the wall is being lowered.
• A diffuser is inserted, after which a mark is made.
• Holes are made by a perforator.
• Fastening is carried out by screws or bolts.

Ceiling diffusers are almost invisible, so they are installed in different places. When installing, it is important to ensure that the product fits into the ceiling, and then the surface will look harmonious.

Cost

The ceiling diffuser, the price of which is quite affordable, can be purchased in conventional building stores or via the Internet. The cost of the products starts from 100 rubles. For this price, you can buy small devices with a diameter of 40-60 cm.

The type of device does not greatly affect the cost. But the popular brand, especially if the product is manufactured by a European company, adds a price 2-3 times. At the same time there is no difference in the distribution of air.

The diffuser is necessary for every room, because it is required to ensure the release of unnecessary air, as well as the arrival of clean air. With the device, the atmosphere in the room will be very comfortable.
