Description
Spencer VB030B-011 Vortex Blower 3.4HP 230/460VAC 3Ph 3450RPM TEFC VBA93010
The Spencer VB030B-011 is a regenerative vortex blower driven by a 3.4HP, three-phase induction motor rated at 200-230/460 VAC, 3450 RPM. Spencer Turbine Company, based in Windsor, Connecticut, manufactures this series for continuous-duty industrial air-moving applications. The blower housing uses a side-channel (vortex/regenerative) design that recirculates air around the impeller to build pressure without the high noise or maintenance demands of positive-displacement blowers. This unit has been tested and is in working order — it powers on and blows strongly. It is currently wired for low voltage (200–230 VAC) and can be rewired for 460 VAC operation.

Applications
Spencer vortex (regenerative) blowers are used across a broad range of industrial and process applications that require a continuous, steady flow of air or gas at moderate pressure differentials. Common uses include pneumatic conveying of dry bulk materials, aeration of wastewater and aquaculture tanks, vacuum lifting and pick-and-place systems, sparging and agitation in process tanks, and combustion air supply for burners and furnaces. The TEFC enclosure and continuous-duty motor rating make this blower well suited for washdown-tolerant or dusty plant environments. Dual-voltage winding (200-230/460 VAC) gives it flexibility across common North American three-phase power systems. Spencer Turbine has been manufacturing regenerative blowers and exhausters in Connecticut since the early twentieth century; their VB series is a long-running product line found in food processing, chemical handling, plastics, printing, packaging, and wastewater treatment facilities.
This Spencer VB030B-011 Vortex Blower has been tested and is in working order — it powers on and blows strongly. It is currently wired for low voltage (200–230 VAC) and can be rewired for 460 VAC use. The unit shows normal industrial wear including surface rust on the motor housing and some paint chips on the cooling end cover, consistent with prior working service. Due to its size and weight (approximately 112 lbs), this item requires freight shipment. Please review our photos and contact us with any questions before purchasing.
