3 A system approach to the task of making problems go away. Corrosive spills in laboratory

Packing litter and dust

Liquids on clean room floor

All the work of a vacuum system is performed by pressure, not suction. In a cleaning application, room air rushing into a cleaning tool carries nearby solids or liquids along with it. There must be an adequate pressure differential at the tool and throughout the hose and tubing system to overcome system resistance and sustain a conveying velocity. To create a high-velocity inrush of air, a Spencer central vacuum system has a powerful vacuum producer, often a multistage unit that builds and holds a high negative pressure, even with several operators on-line at once. Once material is in motion inside a hose and tubing network, the airflow carries it back toward the vacuum producer. Various types of separators are positioned between the pickup point and vacuum source to intercept and collect the conveyed materials, whether wet or dry, usable or disposable. The complete system consists of a pickup point, conveying system, separating stage and vacuum producer.

Large Spencer system has 27 standard overhung vacuum producers arranged in tiers (right), connected to a bank of five centrifugal separators and six tubular bag separators, to serve a cleanroom facility for automated computer disk production.

Special Designs We can honestly say that Spencer makes everything you need in vacuum producers, because we will modify any design to suit your application. These are some examples of the specials already produced: • Alternative drivers such as gasoline, propane or diesel engines. • Alternative drive arrangements such as belt or gear drive, which can be fitted to most vacuum producer types. • Multiple vacuum producers, packaged on a common base. • Special materials such as aluminum, Hastelloy® and stainless steel, and special interior or exterior coatings for vacuum producers. “Triplex” vacuum system at a Connecticut hospital evacuates laser surgery smoke from operating rooms using three Spencer standard overhung vacuum producers, galvanized wet separator, secondary HEPA filter, controls and vacuum tubing network.
