When arranging any room, it is necessary to take care of the quality control of the microclimate. First of all, this refers to humidity and freshness of air, especially in those rooms, the operating conditions of which are quite complex. Effectively cope with the problem will help the installation of a channel fan, about the types and advantages of the use of which you will learn from this article.

Channel Fans - Principle of Device and Functioning

The distinctive constructive solution of channel fans lies in the fact that they are equipped with air conditioning of this type. It is when it is functioning that high-quality air treatment is carried out:

• heat;
• filtration;
• cooling;
• regulation of air supply speed;
• processing and rapid removal of recycled air masses.

A fan is installed in the wall, and the grille is mounted on the surface. It immediately located the line of air ducts. Through them, air falls into the filtration system from the room. There, in a special mixing chamber, it is well cleaned and the distributors are fed back.

Important! Review the video in which the principle of functioning the channel fan is clearly shown to personally make effective.

For the manufacture of the housing of this equipment, a multi-layer canvas are used:

• become;
• plastic;
• combinations of these materials.

All parts are connected by point welding and bolts.

Important! The high performance characteristics of channel fans determine their stable popularity for installation not only in residential buildings, but even in industrial production and large outlets.

Advantages of channel fans

Channel fans have a number of indisputable advantages compared to Babeless - this is:

• higher feed efficiency;
• compact dimensions;
• multifunctionality is the possibility and cooling, and air heating;
• high accuracy balancing;
• long period of operation;
• a small noise level during operation;
• the possibility of uninterrupted operation of the system even in the conditions of an unfavorable environment;
• fast and high-quality cooling system due to special engine protection;
• ease and installation speed;
• the possibility of more rational use of the building volume when laying the air duct line.
  
  

  Important! Channel fans are permissible to install even in space over suspended ceilings, which expands the possibilities of interior design, and the aesthetics of any room is far from the last criterion at arranging their own home, office or outlet. With all the advantages of this equipment, the price of channel fans is not very different from devices for other systems.

                                                                                                       

Types of channel fans

All channel fans presented in the market with modern producers are divided into 4 main categories on the principle of air supply form and structural features of the case - this is:

1. Channel round fan. Such equipment is used to arrange air duct systems with a circular corresponding cross section. It is allowed in this case and the use of a flexible air duct, which brings its advantages when designing and installing a chain.
   

   Important! Additional advantages of these systems are that they are beneficial to manufacture - the technology is the simplest of the existing, and the resistance in the finished form, when the entire line is functioning, is minor.                                                                                                                                                                                                                    

2. Rectangular fan. Applied to picking profile rectangular ducts. The installation of such devices allows the most efficiently and practically to use even a small sub-flow space. Suitable parameters and characteristics are selected based on the source data on the indoors itself, in which the installation is planned.
3. Square fan. This option is less popular, as compared with round, and even rectangular fans, square has a sufficiently large resistance inside the system. In addition, they occupy a lot more space.
4. Centrifugal system with a noise absorbing case. These systems are characterized by the highest efficiency. The soundproofing case guarantees the lowest possible noise background even with high feed rate and air processing. Install such fans in the supply, exhaust and combined systems. An additional advantage in their compactness is if the space is required, but high-quality adjustment of the microclimate in a short time, centrifugal fans will suit the most. For installation, almost any place indoors is suitable, and quick disconnect clamps use to connect to the surface of the walls. The feed rate and modes change is regulated by an electronic high-precision system, so practically do not require additional human participation in the process of functioning.
   
   

   Important! All types of channel fans are used for processing and moving air masses without abrasive and solid particles, as well as explosion-proof gases. The recommended temperature regime has a wide range: -30C - + 40C.

In addition to these 4 types, classify this type of equipment on the principle of system operation on:

• axial, diagonal and radial channel fans;
• with lowered forward either back blades;
• with single and 2-third-sided suction.
  

  Important! Before you give preference to any option and buy a channel fan, specify not only the cost of the equipment. A thorough preliminary analysis of the premises, the whole building, the formulation of technical requirements and the selection of a system suitable for all criteria will be required.

Applying channel fans

As already mentioned, the channel fans are literally universal in use. They are installed:

• in the shops;
• in private homes and cottages;
• at train stations and at airports;
• on shopping and industrial facilities;
• in the premises of warehouses and domestic purposes;
• in offices;
• in restaurants and scale dotters.

Criteria for selecting a channel fan

When buying a channel fan, it is sufficient to clarify such characteristics:

• percentage of efficiency;
• air flow;
• full pressure indicator;
• power of the channel fan;
• rotation frequency;
• cross section and duct profile;
• the level of the noise published.

How to determine the required fan performance?

Perform the calculation of the desired performance on the basis of such data:

• length and width of the room;
• the desired air replacement frequency indoors.
  

  Important! To get the required result, multiply these 3 indicators. Also consider the recommended building standards in the process of choosing the equipment. For example, a channel fan with characteristics at 95-100 m3 / hour is suitable for a part-up bathroom in a residential building.

How to find out a comfortable noise level?

Solve the problem of selecting a channel fan in terms of the noise level is fairly easy:

• if the system is purchased for installation in an apartment or a private house - the optimal solution is 25-30 dB;
• for industrial, commercial and other public places, the indicator may be much higher, since the crowd's natural noise background will be present.
  

  Important! Consider the fact that in complete silence, the sound of 35 dB is already loading a large load on the psyche of man. That is why when buying a fan, proceed from the conditions of future operation of the equipment.

How to check the safety of the fan?

To eliminate the fast output of the system and the emergence of non-repairing breakdowns, be sure to consider the recommended appointment and the design features of the fan. For example:

• special channel fans for the bathroom are resistant to penetration inside the moisture device;
• industrial fans are highly productive and resistant to any aggressive impact;
• mechanisms in a protected case are not only much less emitted noise, but also guarantee high resistance to mechanical influence.
