Blowers

Single Stage Fabricated Centrifugal 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. 
 
Multistage Fabricated Centrifugal Blowers
 
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.
 
Custom Blowers & Gas Boosters
 
For very difficult gas handling jobs, Spencer offers high-performance blowers and gas boosters with special designs and constructions using a variety of high-performance metals such as Hastelloy®, stainless steel and titanium. Typical gases handled include corrosive and toxic sulfides, halogens, acids, flue and stack gases, cyanides and ammonia. Maximum parameters include temperatures to 1100°F, housing design pressures to 1000 PSIG, operating pressures to 300 PSIG.
 
Special Features of Centrifugal Blowers
 
Spencer has a variety of choices to deal with unusual applications. They include special materials, coatings and corrosion allowances for corrosive gases; effective sealing techniques or hermetic, leaktight configuration for hazardous gases; alternative drivers such as gas turbines instead of electric motors; belt drives for blower operation at a specific speed; various drive arrangements and couplings; and accessories from acoustical wraps to vibration isolating pads.
Power Mizer Cast Centrifugal Blower
 
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 28 psig (193 kPa), volume to 35,000 icfm (991 m3/min); power to 2000 hp (1491 kW). 
Vortex Regenerative Blowers
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: 645 icfm (1096 m3/hr volume, 3.9 psi (27 kPa) pressure and 7.6" Hg vacuum.
