Industrial Hb-139 Ring Compressor Blower 208-230 460 Volts 3 Phase

The All-Star HB-139 regenerative blower (often referred to as a ring compressor) is a compact industrial air mover designed for both vacuum and positive‑pressure tasks in process lines. It is driven by a 0.33‑horsepower three‑phase motor and accepts 208‑230V or 460V, 3‑phase power, featuring a two‑pole design that runs at roughly 3,450 rpm at 60 Hz. As part of All-Star’s HB regenerative blower family, the HB‑139 represents a smaller, three‑phase model optimized for reliable continuous operation where space and power constraints matter. Typical applications include material handling, pneumatic conveying, filtration system duties, and other industrial air‑moving tasks that require a compact blower capable of generating vacuum or pressure with a 0.33 HP rating.
