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.
From single-user, mobile vacuum cleaning units to extensive, multi-operator central vacuum systems, Spencer has standard or custom designs for all industrial, commercial and institutional facilities. Besides heavy-duty vacuum cleaning, Spencer systems can perform high-velocity dust collection, pneumatic conveying, liquid pickup, scrap removal, hospital sanitizing and similar intensive applications, using specialized collectors, separators and filtration systems.
