VK 125 EC

VK 125 EC is a 5-inch inline centrifugal duct fan from Vents‑US using an energy‑efficient electronically commutated motor for variable‑speed operation on 120 V, 60 Hz. A backward‑curved impeller in a durable ABS housing delivers rated airflow of 190 CFM (about 323 m³/h) at 0.0 in. w.g., with a listed sound level of 3.4 sones. The fan is supplied pre‑wired with a power cord and includes a mounting bracket for straightforward installation. Designed for round 5-inch ducts, it provides reliable exhaust or supply ventilation in residential and light commercial applications, particularly where longer duct runs favor a centrifugal design. Ball‑bearing construction supports extended service life, and the VK EC series is compatible with speed control to fine‑tune airflow to system needs.
