Disks and Fixture Inside: Stainless Steel 304 BA (EN 1.4301 - L20), respectively, in thicknesses of 0.5 mm and 1.5 mm.

Welding: longitudinal TIG process for the fusion of adjoining pieces, without filler.

Belling: cold moulding, done with a mould and counter mould hydraulic expansion system ensuring calibrated joints with a tolerance of +/- 2mm.

Accessories: triple lip silicone gasket to ensure the joint is sealed; locking band to secure the joint and ensure the continuity of the system.

Evacuation of the products of combustion generated by wood-burning, multi-fuel, natural gas and diesel appliances.

Operation: dry (D) or wet (W).

Pressures: Positive (P1 = 200 Pa), Negative (N1 = 40 Pa).

Operating temperatures: ≤ 200 ° C with silicone gasket and P1 = 200 Pa; ≤ 600°c without silicone gasket and N1= 40 Pa.
