Blowers

Spencer single stage scroll blowers, aeration/ventilation blowers and heavy-duty RB pressure blowers are widely used in Original Equipment Manufacturing applications and in processes that require uniform airflow over an entire volume range. Typical uses are aeration, combustion air delivery, ventilation, materials handling, air curtains and drying. Maximum airflow volume is 50,000 ICFM, maximum pressure 3.5 PSIG. There are three designs of Spencer multistage fabricated machines: standard overhung (SOH), four-bearing overhung (4BOH) and four-bearing outboard (4BOB). Sheet steel construction is standard for blower housings, but other metals can be selected for specialized resistance in cases involving extremely high temperatures, chemicals or corrosive conditions. With housing diameters from 14" to 88", these blowers can handle volume to 25,000 ICFM, pressure to 20 PSIG and vacuum to 15" Hg. In addition to major components of cast iron, Power Mizer blowers have cast aluminum impellers with three-dimensional blades that transfer energy to the airstream with very high efficiency. In continuous-duty industrial processes and wastewater aeration applications, they offer energy savings of thousands of dollars per blower per year. Performance specifications include pressure to 20 PSIG, vacuum to 15" Hg, volume to 40,000 ICFM. Vortex single stage regenerative (side channel) blowers are compact units that are well-suited for in-plant use and for air handling in OEM equipment. They deliver clean, oil-free air without pulsations. Many options are available: TEFC or explosion-proof motors; one-phase or three-phase power; 50 or 60 Hz operation. Maximum performance characteristics: 600 ICFM volume, 3.6 PSIG pressure and 7.6" Hg vacuum.
