In-Line Series
The In-Line Series 2 Ways is built for places where air has to travel far and stay steady — long ducts, complex layouts, or big ventilation systems that can’t afford weak airflow.
At its heart is a high‑efficiency motor paired with an aerodynamically balanced impeller, giving it a mix of power and stability that feels effortless. It moves air with strength but doesn’t waste electricity doing it, so it keeps running costs nice and low.
The body is all metal, made from galvanized steel that’s tough enough to handle vibration, humidity, and time. The shell doesn’t warp or rust easily, even when the fan is working around the clock. You get that quiet confidence of knowing it’s built to keep going — not for months, but for years.
It’s also flexible to work with. The line includes different sizes and configurations, so you can run one fan on its own or combine it with others when you need extra reach through a bigger duct network. It fits neatly into new installs or upgrades without fuss.
And here’s the real strength: long‑distance air delivery. It holds static pressure well, pushing airflow cleanly through bends and long duct runs — perfect for workshops, industrial halls, or any large‑scale projects where airflow matters.
No fancy gimmicks — just solid, reliable engineering that keeps the air moving exactly where it needs to go.
