Pipe 125 SPIRO galvanized 3m INVEST (0.45mm) RZOC125INVEST

Galvanized ventilation duct – a solid solution for your installation

SPIRO duct with a diameter of 125 mm and a length of 3 meters is an element of a ventilation system, designed for use in both residential and industrial buildings. Made of high-quality galvanized sheet metal, it provides durability and corrosion resistance. This is crucial in ventilation systems where moisture and other environmental factors can negatively affect the lifespan of the components.

This duct is used in mechanical and gravity ventilation systems, as well as in heat recovery installations. Its rigid construction guarantees stability and ease of assembly. Thanks to this, both installers and end-users can count on trouble-free use for a long time.

Characteristic features and application

The duct is manufactured by KRZYS-POL and has the "B" mark, which is required for this type of product after June 30, 2019. It also has a KOT certificate, which confirms its compliance with applicable standards. Made of hot-dip galvanized sheet metal (class Z 200–275), it is characterized by high tightness and durability. It is worth noting that ducts with a diameter below 250 mm do not have reinforcing embossing, but maintain adequate rigidity thanks to the precise production process of SPIRO INTERNATIONAL SA.

This duct is ideal for:

• Building ventilation ducts in mechanical ventilation systems
• Creating supply and exhaust air installations
• Assembly of heat recovery systems
• Applications in residential, commercial and industrial buildings
• Connecting with other elements of the ventilation system – fittings, elbows, reductions, etc.

Product advantages in practice

• Corrosion resistance: Galvanized sheet metal provides long-lasting protection against the effects of moisture and other atmospheric factors. This translates into lower costs associated with replacing installation elements in the future.
• Tightness: Precise workmanship guarantees minimal air losses, which affects the efficiency of the entire ventilation system.
• Compliance with standards: Having the "B" mark and KOT certificate proves that the product meets all required safety and quality standards.
• Ease of installation: Rigid construction makes it easier for installers and reduces the time required to install the system.
• Leakage class D: Certification confirms the high quality of workmanship and reliability of the product in professional HVAC installations.
• Weight: 4.8 kg – facilitates the transport and assembly of individual sections of the pipe.
