Product catalog summary
Description: The TRZT is a circular air-tight volume control damper made of galvanized steel, classified as air-tight class 4 according to EN1751. It features a steel blade axis mounted on bronze or nylon bushes, depending on the diameter, and a silicon sealing gasket on the blade. It can be operated manually or with an electric motor, suitable for use in air-conditioning, ventilation systems, air handling units, and various industrial applications. The maximum working temperature is 70°C.
Dimensions: Available diameters (Dn) range from 100 mm to 710 mm.
Construction: The damper is constructed with a galvanized sheet steel case and blade, with bushings made of bronze or nylon.
Other Versions: - TRZT F: Flanged execution.
- TRXT: Stainless steel execution (AISI 304).
- TRZT MOT: Suitable for electric motor operation.
Accessories: - T1, T2, T3: Manual lateral control with stop.
- T7: Motor for electric drive 5 Nm.
- T8: Motor for electric drive 10 Nm.
Performance: The damper's performance is illustrated in graphs showing pressure drop (ΔP) against air velocity (v) and volumetric air leakage, indicating its efficiency in maintaining air-tightness.
Specifications: The damper is specified with various dimensions for different diameters, including thickness, axle diameter, and length. Manual control options (T1, T2, T3) and motor options (T7, T8) are specified for different diameter ranges.
