Round casing made of galvanised sheet steel in single walled/double walled design with thermal and acoustic insulation. A 4-spoke calliper with 12 measuring points ensures a measurement accuracy of ±2%. The Barcol-Air damper flap (double layer with SBR seal in-between) is mounted in low-friction nylon bearings. Shaft material: aluminium.
Round casing made of PPS. Differential pressure is measured by an orifice plate and averaged by 2 x 4 measuring points. The Barcol-Air damper flap has a double layer made of PPS plastic with an SBR seal in-between. Shaft material: V4A.
