Uni-Drive Ductless Jet Fans – UJF Series

Uni-Drive offers a dedicated range of ductless jet fans under the UJF Series, engineered for efficient air movement in car parks and large enclosed spaces. These jet fans are designed to generate high-velocity airflow, guiding polluted air toward exhaust points and improving circulation without extensive ductwork.

The UJF Series is suitable for modern performance-based ventilation concepts where space efficiency, reliability, and ease of maintenance are essential.


Available UJF Models

UJF Series – Ductless Jet Fans

Ceiling-mounted, direct-drive axial jet fans designed for continuous operation in basement and multi-storey car parks. The series is available in multiple thrust and diameter options to suit different ceiling heights and zoning strategies.

Typical model range includes:

  • UJF-180 – Compact unit for low-ceiling car parks

  • UJF-200 – Standard duty for general applications

  • UJF-250 – Higher thrust for long-throw requirements

(Model sizing and selection are based on project layout and performance criteria.)
