The Booster 9238 is a 92 × 92 × 38 mm high-pressure booster with dual-ball bearings as standard. It mounts in-line on ducting or directly on an enclosure wall to push air through long, restrictive paths.
Staged behind a primary fan, the Booster 9238 adds static pressure in a 92 × 92 × 38 mm format — a common approach for ventilation lines that lose airflow across filters and bends.
Our Shenzhen line builds the Booster 9238 end to end — winding, balancing, assembly and 100 % aging. Because no step is outsourced, we can hold batch consistency and adjust bearing grade, lead length or speed binning to your production schedule.

Booster 9238 uses a high-static-pressure impeller and stator design that keeps airflow under strong back pressure — suited to dust filters, long ducts, range hoods and dense radiators where ordinary fans lose most of their CFM.
Yes, two Booster 9238 units in series roughly add their static pressure capability. Mount them with a short spacing section and confirm the second fan's inlet conditions with our engineers.
Auto-restart, polarity protection, tach and alarm signals are available. For humid or oily environments, conformal-coated PCBAs and IP54 grilles can be added.
Samples ship in 5–7 working days; volume MOQ is typically 200–500 pcs depending on configuration. Custom voltage, speed or connector versions need 10–15 days for first samples.
