We custom-designed this high-pressure radial induced draft fan for a scrubber application, with alloy 2205 airstream construction, custom purge air shaft seals, pie-split housing, and an integral inlet box. Configured as a center-hung Arrangement 7 fan, a flexible coupling is used to connect the fan shaft to the motor shaft, and the entire fan assembly is mounted on a unitary base. The application required a severe duty motor rated for use with a Variable Frequency Drive (VFD).
Application: Scrubber
We provided these custom high-pressure SCR blowers (one primary with an identical redundant/backup blower) for this mission-critical Selective Catalytic Reduction (SCR) application. Designed for high-temperature operation at 800 degrees max design temperature with a tight 15-degree min/max rate of temperature change. The blowers have 15 HP IEEE841-rated premium-efficiency, severe-duty motors to meet the high standard required for operation in the petroleum and chemical industry.
AirPro built two exhaust fans for a Dry Flue Gas Desulfurization (SDR) system installed at a US copper mine. All parts in contact with the air stream were constructed with 316 Stainless Steel including all fan accessories.
