In numerous large, medium and small enterprises in the agricultural sector, the choice of air duct is an essential part of a well-functioning ventilation system. Properly selected air ducts create channels for the movement of air masses. One by one, clean air enters the premises, and by the other, exhaust air saturated with carbon dioxide and other pollutants is taken in.
In order to answer the question of how to choose an air duct for a particular enterprise, several important factors must be taken into account. For example, duct pipes made from a polymer composite material can be made into an optimal aerodynamic shape. Therefore, they create minimal resistance to air movement. This means that dust and other small particles of dirt are more efficiently removed from production facilities. Also learn more about vent and duct cleaning.
What material to choose an air duct?
Until recently, the most common material for creating ventilation was thin steel sheet material in the form of a circle, square or rectangle. But, with the development of technology, polymer composite material (PCM) has shown much more advantages for its use in agriculture, classical production and in the chemical industry. The main advantages of a fiberglass duct can safely be attributed to:
The material is resistant to significant temperature differences.
The material has a significantly greater corrosion resistance than steel.
The material is much lighter than iron.
From the increased vibration created by fans, cracks and other physical defects do not appear.
On the surface of fiberglass, dust and other factors polluting the air duct are practically not retained.
Now you know how to choose a duct according to the type of material. In order not to face the problem of regular cleaning and partial disassembly of the system in the future.
Square or circle?
Professionals, answering the question of how to choose an air duct, first of all recommend paying attention to the specifics of the room. The round section has its advantages, since it practically does not create additional resistance to the movement of air masses. That is why circular air inlets and exhausts are so popular on livestock farms, where timely ventilation is important to maintain the health of animals and especially birds.
If the ceilings are low and space is very limited, the choice falls on rectangular and square fiberglass ducts. They are more difficult to manufacture and their cost is slightly higher, but their installation allows you to achieve high performance and no piling up of air ducts in the ceiling area.
Important: sealing joints is one of the most important indicators of the quality of air ducts. Fiberglass products are so accurate in relation to each other, therefore, it is not difficult to achieve their high-quality connection. In addition, minimal expansion and contraction under the influence of temperature changes does not violate the tightness during everyday operation.
Regulatory Compliance
If desired, air ducts can be made from almost any material. But, not all of them will meet the standards adopted in the country. Fiberglass products not only meet many certification standards, but are also successfully used almost all over the world. The thickness of the material, reliability of operation, self-cleaning efficiency and other equally important indicators are superior to steel and polymer products. How to choose an air duct for many years to come? A fiberglass product will provide the necessary level of reliability.
Industrial operation
The ventilation system consists of many products. Starting with numerous grilles, and ending with a powerful fan capable of bringing out several tens of cubic meters of air masses in seconds. But the main load is taken by the air duct. If the product is correctly selected for certain operating conditions, it will serve for years at an enterprise or farm, and does not require increased attention from maintenance.
As mentioned above, fiberglass is not inclined to accumulate and retain various pollutants on its surface. The naturally slippery inner surface of the air duct pushes dust and small particles up to the filter or air pump. But, for unscheduled cleaning, or accidental ingress of too large objects in the ventilation system, it is necessary to leave technological hatches.
As practice has shown, the installation of fiberglass air ducts significantly reduces their cost in the process of trouble-free operation. The multilayer material does not deteriorate over time, does not corrode and, if necessary, can be reused. How to choose an air duct that will not need frequent maintenance and repair in the future? Choose a polymer composite, and it will definitely not let you down at the most crucial moment, ensuring reliable operation of ventilation on a farm or in a production workshop.
