Make your ducting and venting run efficiently and smoothly with S & P duct fan accessories. The TD Series Connection Kit is made for TD series bathroom fans and kitchen fans and has a twin base connection. Attach two lengths of ducting with the TD Series Circular Connector. Designed for TD series bathroom and kitchen fans, the connector is available to fit 5", 6", 8" and 10" ducting. The TD and CAR Backdraft Dampers prevent air leakage in your inline fan setup. The Adjustable Air Inlet Valve is available in metal or plastic and has an adjustable central valve to regulate air flow. The Louvered Shutter Wall Cap is made of strong, UV-stabilized plastic material to ensure years of use. Lower fan noise by 50% with the Inline Duct Silencer. Made from galvanized steel, the silencers feature rubber seals on the inlet and outlet. The Connector Clamps have an insulated rubber duct seal that keeps your ducting secure. Made of galvanized steel, the Roof Cap features a damper flap closure to allow air to be discharged properly and a bird screen to keep the vent unobstructed. The Fan Controls are available in a variety of styles including slide type, push button timer, rotary type, delay timer and spring-wound timer to accommodate any setting. The Dryer Booster Pressure Switch uses its premium air pressure sensor to identify when the dryer is in operation. The timer module keeps the fan on for ten-minute intervals when the dryer is in use. The High Current Switch activates the booster fan when the dryer is running and prevents false activations. Keep your duct fan free of lint with the Dryer Lint Trap. Made of metal, the lint trap has a side door for easy lint removal. The filtration box is designed for environments with excessive dust and can be used with S&P PV and TD series fans.
