Vacuum Producers & Vacuum Separators
Vacuum Producers
All of the Spencer blower types are equally useful as vacuum producers for systems that “pull” rather than “push” air. This latitude is sure to meet any desired vacuum and volume performance level.

Standard Overhung Fabricated Multistage Centrifugal
Our most popular design, thousands and thousands sold since 1905. The SOH has impellers mounted on an extended motor shaft. The simple two-bearing design reduces maintenance.
Vacuum: to 8" Hg
Volume: to 7,000 ICFM
Power: to 150 HP

Four Bearing Overhung Fabricated Multistage Centrifugal
Impellers are mounted on the vacuum producer shaft, which is coupled to a standard shaft motor. Rotating elements are supported by a rigid bearing bracket.
Vacuum: to 10" Hg
Volume: to 8,000 SCFM
Power: to 250 HP

Four Bearing Outboard Fabricated Multistage Centrifugal
For higher pressure applications. Impellers are mounted between supporting bearings. Outboard bearings are a matched set, one for radial loads, the other for thrust loads. Inboard bearing absorbs a share of the radial load. The vacuum producer is coupled to a standard shaft motor.
Vacuum: to 14" Hg
Volume: to 15,000 SCFM
Power: to 1250 HP

Power Mizer® Cast Multistage Centrifugal
Made with rugged cast iron and cast aluminum components for extra-heavy-duty service. Uniquely shaped impellers and other advancements produce a peak adiabatic efficiency about 80%.
Vacuum: to 17" Hg
Volume: to 16,000 SCFM
Power: to 1250 HP

Single Stage Centrifugal
Scroll design machine for high volume and low vacuum requirements.
Vacuum: to 3.5" Hg
Volume: to 6,000 SCFM
Power: to 60 HP

Vortex® RegenerativeCompact, single stage regenerative units suitable for limited-space installations.
Vacuum: to 8" Hg
Volume: to 600 SCFM
Power: to 15 HP
Separators and Collectors
In separators, Spencer offers standard and high-efficiency cyclone centrifugals, stationary and mobile liquid separators, even special units for flammables and other sensitive materials. There are dry and liquid separators; several filtration types with manual or automated cleaning; preseparators; and specials such as Bag In/Bag Out separators. Choices include filter bag, Jet Pulse and cartridge filters; filter cleaning can be manual or automatic as desired.

Jet-Clean® Separator.jpg)
Centrifugal separators usually provide primary separation before a filtration separator. They are typically equipped with a removable dirt can or hopper bottom for disposal of collected material. High-efficiency separators use a cyclone vortex action for greater dirt removal or pneumatic conveying. Other designs include drum-top preseparators and various liquid separators for use in wet vacuum systems or in dry systems where they intercept liquids to avoid system contamination.
A properly sized tubular filter bag separator may be used alone or downstream from a centrifugal type to trap over 99% of the remaining solids, even with difficult powdered materials. Our Jet-Clean® design adds pulse-type filter cleaning, which can be used with filter bags or cartridges. Automated, sequential cleaning allows the separator to operate continuously.
Special designs in separators can be as simple as a reduced height to fit under mezzanines or an oversize trapdoor to discharge bulky materials, on up to highly engineered designs such as immersion separators with water filtration chambers to handle sensitive flammable materials or Bag-In/Bag-Out separators for hands-off filter changes when collecting toxic materials such as arsenic powder.
Dozens of components and accessories are available for specific functions, safety precautions or operating convenience. For example, discharge valves can release collected materials continuously or upon system shutdown. There are explosion relief ports, motorized filter bag shakers, vacuum gauges, debridgers, sprinkler head connectors, grounding systems, support frames and special fittings - everything it takes to provide your definition of convenience.
