low-pressure fan

Low-pressure fans are designed to deliver high volumetric airflow at minimal static pressure, making them ideal for applications such as warehouse cooling, workshop ventilation, and tunnel inflow. Their axial or mixed-flow designs prioritize flow rate over pressure rise.

Typically constructed with lightweight aluminum or galvanized steel impellers, these fans achieve 20,000–200,000 CFM at static pressures below 1 kPa. The open blade profile minimizes turbulence, ensuring efficient air movement.

Integration with variable frequency drives (VFDs) allows on-demand airflow, matching fan speed to temperature or occupancy sensors for energy savings up to 35%. Low-noise designs and acoustic housings reduce sound levels, enhancing workplace comfort.

Maintenance is straightforward with external grease fittings, quick-release inlet guards, and sealed bearings. Low-pressure fans provide cost-effective, reliable ventilation in low-resistance environments.
