The Booster 4028 (Version 1) is a 40 × 40 × 28 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 4028 (Version 1) adds static pressure in a 40 × 40 × 28 mm format — a common approach for ventilation lines that lose airflow across filters and bends.
Production of the Booster 4028 (Version 1) is vertically integrated: winding, impeller balancing, assembly and burn-in happen in-house, and each unit is functionally tested before shipment. Samples are validated at your stated duty point so the mass-production curve matches what you measured.

Booster 4028 (Version 1) 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 4028 (Version 1) 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.
