The constant exchange of "old" air from the rooms in the home with fresh outside prevents the occurrence of many allergies and allows easier breathing. This ensures faster sleep and promotes deeper sleep. For this purpose you need modern and technological ventilation, and the metal and flat rectangular air ducts of Chernev Clima will provide the best conditions for implementation and durability of the installation. Let's see what they are made of and what is their application, their advantages and disadvantages, how does Chernev Clima outperform its competitors?

What are they made of

Among the rectangular air ducts offered by Chernev Clima, you will mainly find models made of galvanized sheet metal and stainless steel. The first are significantly lighter than the other. Both types are preferred in case of aggressive working conditions, such as at high or low temperatures, water and humidity. They are also used in case of probability of mechanical loads and the need for resistance to aggressive environments. Depending on the conditions, the rectangular air ducts can have different sheet metal thicknesses, which helps to adapt them.

Rectangular air ducts made of galvanized sheet metal are suitable for work in non-aggressive environments, but with high levels of humidity and ambient temperatures up to a maximum of 80°C. Stainless steel models are used in case of need to work in aggressive conditions, such as high temperatures and the effects of destructive reagents. Their sizes and parameters can be different, and the limits are almost unlimited, as it is necessary to submit an application with the necessary parameters.

The connection of the individual rectangular air ducts is done through special flanges or without them. In the latter case, additional metal brackets are used. In the production of galvanized sheet models, the zinc layer is applied by cold or hot method. The first is based on the application of zinc powder on the surface, and then polymerization is performed, where the powder melts. In the hot version, the products are melted in molten zinc, the temperature of which reaches 500°C.

Application

Most often, rectangular air ducts are used in residential buildings, supermarkets, public institutions, industrial enterprises and many others.

The types made of galvanized sheet metal are quite preferred, as they have good aesthetics and allow fitting into the modern interior. They are cheaper and lighter, providing faster and more efficient installation when building a ventilation system. Rectangular air ducts are also used as an aspirator, removing excess odors from the room to the outside. They are used in the construction of smoke and air conditioning systems in residential buildings, health care facilities, shopping and entertainment centers, educational institutions, etc.

Advantages

The reasons for the increased demand for metal rectangular air ducts are:

  • Maximum pressure density to the plane of the surrounding structures (wall, ceiling, etc.);
  • Increased compactness and aesthetics of the design - allows easy and quick hiding of pipes in ceiling or floor niches, behind wall structures, in cabinets, etc .;
  • Simplicity in installation activities, due to the systems for quick assembly, using special fittings and other additional elements;
  • Increased resistance to transverse loads, torsional and tensile forces. This is due to the right angle of the planes of the profile, allowing the pipes with longitudinal seams to withstand heavy loads;
  • High level of practicality - the shape and flat side surfaces allow easy and quick attachment of additional parts and fasteners;
  • Increased durability and longevity - an average of 15 years or more;
  • Anticorrosive properties - no corrosion and rust on the surface, even when working in high humidity.

Disadvantages

Metal rectangular air ducts are significantly more expensive than plastic, for example. They are more difficult to install due to their increased weight. They increase the difficulty of cleaning, precisely because of the presence of internal corners in which dirt accumulates the most. The use of metal rectangular air ducts, ventilation and air conditioning pipes can lead to increased noise during operation, as turbulent areas are formed. The prices of these products are significantly higher and require a larger initial investment.

Among the major disadvantages of rectangular ducts is the larger space they occupy in the room, compared to, for example, their round counterparts. This is especially true when the installation is external and the room is limited in size, where the goal is maximum optimization of space and practicality in use.
