At Alnor, we take care of every smallest detail in a complex ventilation system. One of the most important elements in this type of installation are rectangular ventilation ducts.
Rectangular ventilation ducts are available in low-pressure and medium-pressure versions, as well as a version for smoke extraction systems. Our range also includes ducts insulated with mineral wool in the middle of the cross-section, which gives them high acoustic and thermal properties. In the case of thermal insulation on the outside of the duct, it is possible to cover it with any aluminium, galvanised or acid-resistant sheet metal.
In situations where there are large cross sections in the installations, additional straight or cross reinforcements are made depending on the size of the duct and the anticipated pressure in the installation.
Rectangular ventilation ducts are very popular due to their versatility and efficiency. The most common dimensions of these ducts range from 200 mm to 1000 mm in width and from 100 mm to 500 mm in height. This makes them easily adaptable to a variety of ventilation systems in both small and large buildings.
The standard dimensions of the rectangular ducts ensure optimum airflow, which translates into the efficiency of the entire ventilation system. Alnor offers the possibility to tailor the dimensions of rectangular ventilation ducts to meet individual customer needs. Thanks to a flexible approach and modern production technologies, it is possible to manufacture ducts with non-standard dimensions, which allows for a perfect fit to specific installation conditions.
Rectangular ventilation ducts are widely used in various types of buildings and ventilation systems. They are particularly recommended for installations in industrial, commercial and residential buildings where efficient air distribution is required. Thanks to their design, rectangular ventilation ducts enable optimum use of space, which is extremely important in areas with limited installation space.
In industry, rectangular ventilation ducts are often used to extract pollutants, dust and fumes, thus ensuring a healthy and safe working environment. In commercial buildings such as shopping centres, office buildings or hotels, rectangular ventilation ducts are used to ensure adequate air circulation, which contributes to the comfort of the occupants.
In residential buildings, rectangular ventilation ducts are mainly used in mechanical ventilation systems, which ensure effective removal of moisture and pollutants from rooms. Steel ventilation ducts, available in the Alnor offer, are characterised by high strength and resistance to corrosion, which guarantees their long life and reliability.
When selecting rectangular ventilation ducts, it is worth paying attention to several key aspects that will ensure the optimal functioning of the ventilation system. First of all, the dimensions of the rectangular ventilation ducts that will best suit the requirements of the installation should be accurately determined. These dimensions should be adapted to the volume of air flowing and to the space in which the ducts will be installed.
Another important element is the material from which the rectangular ventilation ducts are made . Steel ventilation ducts are characterised by high strength and corrosion resistance, making them durable and reliable for long-term use. It is also important that the ducts have adequate seals to prevent leaks and provide effective sound insulation.
When choosing rectangular ducts, it is also important to pay attention to their compliance with quality standards and certificates. Products meeting the highest standards guarantee safe and efficient operation of the ventilation system. Alnor offers rectangular ventilation ducts of various specifications, which are fully compliant with the applicable standards, thus ensuring their high quality.
