In-Line Series is a galvanized inline duct fan built for stable, energy-conscious airflow through concealed ventilation routes, complex ductwork and long-distance air delivery.
In-Line Series is designed for duct systems that need compact installation, strong static pressure and reliable long-distance air delivery.
Its galvanized metal body, centrifugal impeller and broad model range make it practical for bathrooms, offices, commercial rooms and larger ducted ventilation projects.
Built for efficient duct ventilation, In-Line Series combines motor efficiency, galvanized construction and strong static pressure.
The body fits ceiling and duct spaces without bulky equipment.
Model range supports small and medium room ventilation.
Published pressure data helps match duct resistance.
Durable casing supports long-term use.
High and low operation helps tune airflow and sound.
Multiple sizes help match common duct diameters.
