absorption tower fan

An absorption tower fan powers gas flow through packed or tray absorption towers, enabling efficient mass transfer between the gas phase and liquid absorbent. It removes acid gases, SO₂, or ammonia from process streams.

Centrifugal fans deliver 5,000–100,000 CFM at pressures to 6 kPa, constructed from corrosion-resistant alloys or lined steel to withstand acidic environments.

Variable frequency drives (VFDs) allow flow adjustment based on differential pressure across the tower, ensuring consistent scrubbing performance and energy savings.

Maintenance features include quick-access panels, external lubrication points, and condition monitoring. Absorption tower fans are indispensable in power plants, refineries, and chemical processing.
