Pipe 250 SPIRO galvanized 3m INVEST (0.45mm) RZOC250INVEST

Robust galvanized spiro duct for ventilation systems

Spiro galvanized duct with a diameter of 250 mm and a length of 3 meters, manufactured by KRZYS-POL, is a reliable element of ventilation installations. Made of galvanized sheet metal with a thickness of 0.45 mm, it ensures durability and corrosion resistance. It is designed for the construction of ventilation ducts in gravity and mechanical systems.

The duct has a "B" mark, which is required for products of this type after June 30, 2019, and a KOT certificate, confirming its quality and compliance with standards. This guarantees that you are investing in a proven and safe product.

Application and structural features

Spiro ducts are characterized by rigidity due to external reinforcements, which translates into the stability of the entire ventilation system. They are widely used in both residential and industrial buildings, in ventilation, heat recovery and air conditioning installations. The ability to connect with a wide range of accessories – anemostats, elbows, tees or dampers – makes it easy to tailor to individual project needs.

It is worth remembering that due to the limitations related to the dimensions of courier shipments, ducts with a length of 3 meters may be shipped in two sections of 1.5 meters each. In the case of personal collection or own transport, delivery of the duct in one piece is possible. To connect two ducts, it is necessary to purchase a coupling – also available in the offer.

Safety and compliance with standards

The product meets all required safety standards and has the necessary certificates. The galvanized surface provides protection against corrosion, which extends the life of the duct and minimizes operating costs. By choosing this Spiro duct, you are investing in a durable and reliable solution for your ventilation system.
