S&P TD SILENT series: Silent In-Line Circular Duct Fan
Capacity table and technical specifications of every model in the S&P TD SILENT series.
The S&P TD SILENT series consists of mixed-flow in-line fans that connect directly to circular ducts. The silencer in the casing keeps noise low, and the motor has overload protection. They are used for ventilating bathrooms, toilets, offices and kitchens.
Models from Ø100 to Ø160 mm have plastic casings; Ø250 and Ø315 mm models have metal casings. Speed is set with an REB series speed controller or, on 3V models, with the INTER 4P step switch.
