The VK 200 is Vents‑US’s 8‑inch inline centrifugal duct fan in the VK Series. It connects to 200 mm round ducting and uses a backward‑curved impeller driven by a sealed external‑rotor AC motor with thermal protection. The UV‑resistant plastic housing includes an adjustable mounting bracket and a pre‑wired power cord for quick installation in any orientation. Intended for supply or exhaust ventilation, the VK 200 is suited to long duct runs and higher static pressure applications in workshops, and equipment cooling. Manufacturer data lists a maximum free‑air flow of 507 CFM (≈861 m³/h) at 0 in. w.g. and 120 V/60 Hz operation.
