Accessories for flue gas extraction and ventilation

The solution

What does it involve?

Our flue gas ducts are designed to operate at low flue gas temperatures, making them ideal for condensing boilers. Constructed using a male-female socket system and EPDM gaskets, they are all tested and certified to H1 pressure resistance (5,000 Pa).

Groppalli boasts the widest range of diameters on the Italian market, covering both single-wall and coaxial systems: Ø 50, 60, 80, 100, 110, 125, 160, 200, 250, 300 and the coaxial sizes 60/100, 80/125 and 100/150.
