VK 150 is a 6-inch inline centrifugal duct fan from Vents‑US’s VK Series, built for long duct runs and high static pressure systems. It uses a backward‑curved centrifugal impeller and a sealed external‑rotor AC motor (120 V, 60 Hz) inside a UV‑resistant, 5VA‑rated plastic housing. Free‑air performance is up to 317 CFM, roughly 539 m³/h, through 6-inch (150 mm) ducts. The unit comes pre‑wired with an included mounting bracket, supports installation at any angle, and features thermal overload protection and long‑life bearings for continuous operation. At 0.2 in. w.g. static pressure, airflow is rated about 290 CFM. Typical uses include utility rooms, equipment cooling, and grow spaces requiring a 6-inch in‑line booster with dependable, low‑maintenance operation.
