Hon&Guan’s PowerDual P3 is a 3-inch (75 mm) inline duct booster fan supplied with a stepless speed controller and US plug. Designed for boosting airflow in small ducts, it delivers a maximum of 120 CFM (about 204 m³/h) and uses a DC motor rated at up to 9000 RPM while drawing approximately 20 W. The controller lets users balance airflow and noise; the brand lists typical sound at 42 dBA. The unit operates on 100–240 V AC and includes integrated mounting features for straightforward installation in short duct runs or devices like small grow setups. This P3 size corresponds to 75 mm ducting within Hon&Guan’s lineup and is part of the PowerDual series with in-line speed control.
