Circular ducts and fittings
Circular ductwork are an important element of every ventilation system. Discover the offer of top quality products from Alnor!
Round duct system for ventilation - our offer
Ventilation ductwork is a system for the extraction and distribution of fresh air in industrial, single-family and multi-family buildings.
The ventilation system includes, among others, spiro pipes, pressed and segmented bends, tees, reductions, nipples, plugs and stubs - pressed and segmented - in diameters from 80 to 1600 mm.
Typical ventilation is made of galvanised sheet, and when the fittings are additionally equipped with a gasket, they meet tightness class D according to the PN-EN 12237:2005 standard. Making ventilation elements of acid-resistant or aluminium sheet allows them to be used in areas with significantly increased humidity or where ventilation pipes come into contact with chemical agents.
Spiro fittings
Circular ventilation fittings are key elements in ventilation systems. Their most important advantage is that they are easy to install and highly airtight, so that air can be distributed efficiently.
The fittings include elbows, tees, reductions or caps. Each of these elements is made of durable materials that ensure long-lasting and trouble-free operation of the system. Standard fittings are manufactured from galvanised sheet, but we also offer acid-resistant sheet and aluminium versions on request.
Thanks to their design, fittings fit perfectly with spiro pipes to form a comprehensive round duct system. Such a solution is ideal for use in industrial, single-family and multi-family buildings, ensuring effective ventilation in all conditions.
Gasketed fittings
Gasketed circular ventilation fittings are a reliable solution for ventilation systems where high tightness is required. Gaskets placed at the joints guarantee minimum air loss and prevent dirt from entering the system.
Our ventilation fittings equipped with gaskets meet the requirements of air tightness class D according to EN 12237:2005. They are therefore ideal for applications where precise control of the air flow is necessary - such as laboratories, hospitals or industrial plants.
In our range you will find a variety of gasketed fittings - elbows, tees, reductions and plugs, available in diameters from 80 to 1600 mm. All components are made of the highest quality materials, so they are resistant to damage and serve their function for a very long time.
Ventilation bends
Ventilation bends are an indispensable element in ventilation systems, allowing the direction of air flow in ducts to be changed. Our products are characterised by high quality workmanship and excellent tightness, which affects the efficiency of the entire system.
Ventilation bends are available in a variety of angles which allows for flexible adaptation of the ventilation system to the specific needs of the building. Made of galvanised sheet, and also available in acid-resistant sheet and aluminium versions, Alnor products are resistant to corrosion and mechanical damage.
We offer pressed and segmented elbows, which are easy to install and work perfectly with other elements of the circular duct system. Thanks to their precise workmanship and the use of modern technologies, our elbows ensure minimal pressure losses and quiet operation of the ventilation system.
By choosing ventilation elbows from Alnor, you can be sure that you are receiving a product that meets the highest standards of quality and durability, ensuring long-lasting and reliable operation of the ventilation system.
