Utility Blower. IUF series
IUF (Utility Set) centrifugal fans are SWSI general-duty air handling units designed for both supply and exhaust functions in commercial, institutional, and industrial HVAC applications.
The IUF series features a computer-aided, backward-curved centrifugal impeller. This heavy-duty, non-overloading aluminum wheel (with steel option for heat and smoke extraction) provides high aerodynamic efficiency and low sound output.
All major components—including the impeller, venturi inlet, fan casing, and support frame—are engineered to deliver stable performance and long service life. The fan housing is fabricated from heavy-gauge steel using fully welded construction to ensure structural strength and durability.
Motors and drive assemblies are specifically selected and tested to withstand continuous operation and demanding site conditions. A comprehensive range of accessories is available to accommodate different system and installation requirements.
IUF centrifugal blowers are manufactured to provide end users with reliable, energy-efficient air movement solutions. Many premium features are supplied as standard that are typically optional with other manufacturers. Every IUF unit is fully assembled, factory-adjusted to the specified operating speed, and performance-tested before shipment.
