The TD Series (TD-MIXVENT and TD-SILENT) fans are the top selling product in the S&P product line across the globe, but these inline mixed fans are not your typical exhaust fans. Designed as fans for general residential ventilation, the TD series of fans are the ideal solution for bathroom and kitchen range hood exhaust. The unique design of the TD Series provides the user with an easy to install, simple to maintain, quiet, yet effective ventilation fan. All models include a “removable body” feature that enables the motor-impeller assembly to be completely removed or replaced without the need to interfere with the attached ducting. Unlike traditional ceiling mounted bathroom fans the TD fan is mounted in the duct work away from the inlet resulting in virtually silent ventilation. S&P TD-MIXVENT & TD-SILENT series of in-line duct fans have been specially designed to maximize the airflow performance with minimal noise levels within the smallest and most compact of housing sizes. This makes the TD-MIXVENT & TD-SILENT series the ultimate solution for small to medium sized ventilation installations which require a high airflow to pressure ratio and occupy only the minimum space possible. The TD fan is capable of running continuously at a low speed which is unheard of with a traditional ceiling mounted bathroom fan. The entire TD line is ENERGY STAR® Qualified and the performance is HVI Certified. All this combined makes the TD fan the ideal solution to help meet ASHRAE 62.2, California Title 24 and CALGreen ventilation requirements. S&P offers multiple low cost solutions to meet continuous ventilation codes when using a TD fan in for bathroom exhaust. If that isn’t enough S&P’s TD fans come with a 5-year warranty, making a fan you can truly fit and forget.
