Air ducts

Air ducts are channels through which air moves between ventilation equipment and the serviced premises. It is through them that supply air is delivered to the required zones, and exhaust or polluted air is vented outside. Without a high-quality duct network, even a powerful fan will not ensure uniform air distribution throughout the building.

The efficiency of the entire system depends not only on the equipment's performance but also on how correctly the ventilation pipes are selected: their cross-section, material, and routing configuration directly affect the flow velocity and pressure loss level.

Where air ducts are used

The main areas of application are residential buildings, office centers, production workshops, warehouses, and catering establishments. In each of these cases, different requirements are imposed on the network: in domestic settings, priority is given to quiet operation and aesthetic appearance, whereas in production, resistance to loads and chemical inertness of the material are more important.

Ventilation air ducts are selected taking into account the type of facility: more resistant materials are used for rooms with high humidity or aggressive environments, while standard solutions are sufficient for ordinary office spaces. Often, the duct network is combined with industrial fans, forming a unified air supply and exhaust system.

Types of air ducts

Ventilation exhaust pipes differ in cross-sectional shape, flexibility, and installation method. Each type has its own advantages depending on the configuration of the ventilation network that needs to be organized in a specific room.

Round air ducts

They have a structural advantage in the form of minimal aerodynamic resistance, which ensures high airflow efficiency with lower energy consumption. Areas of application include both residential and industrial facilities with straight routing sections.

Rectangular air ducts

Used where space is limited and a round cross-section cannot be conveniently placed. An installation feature is the ability to fit tightly against walls and ceilings, saving the useful height of the room.

Flexible air ducts

The installation advantage is the speed of setup and the ability to bypass obstacles without additional fittings. They are actively used in complex system configurations where the route has several turns over a short distance.

Insulated and uninsulated air ducts

The difference between them is the presence of a thermal insulation or sound-absorbing layer. Insulation is needed where the duct passes through unheated zones or near residential premises to reduce the noise level from the airflow.

Air duct manufacturing materials

Ventilation air ducts are made from various materials, and each of them affects the durability of the system and the air exchange in the room in its own way.

• galvanized steel;
• stainless steel;
• aluminum;
• plastic (PVC).

Galvanized steel is the most common option due to the combination of a low price and corrosion resistance under normal operating conditions. Galvanized ducts are well suited for most civil and some industrial facilities where there is no direct contact with aggressive substances – for a more accurate selection of the cross-section, it is worth focusing on the required ventilation duct for a specific system load.

Stainless steel is used where there is high humidity or contact with chemically active environments – food production, laboratories, and specific sections of industrial workshops. Aluminum ducts are valued for their lightweight construction and ease of installation on complex routes where low element weight is important.

PVC plastic air ducts are characterized by corrosion resistance, affordable price, and ease of connecting individual sections. For high-quality installation of such a network, appropriate fittings will be required – tees, elbows, and adapters, which ensure the tightness of connections at turns and branches of the route.

Why you should buy air ducts specifically from Ventilation Service

The choice of air ducts affects the operation of the entire ventilation system, so it is worth contacting a supplier who offers not only products but also project support.

• wide assortment of round, rectangular, and flexible air ducts;
• assistance in selecting the cross-section and material for a specific facility;
• professional consultations on insulation and fittings;
• high-quality equipment from verified manufacturers;
• warranty on all products;
• delivery across Ukraine;
• possibility of comprehensive ventilation system equipment along with fans and additional equipment.

This approach allows selecting air ducts that meet real operating conditions, rather than just the cheapest option available in stock.
