Spencer is already dealing with the increasing global concerns of energy and the environment, applying our design experience and engineering skills to new concepts that deliver very high efficiency, energy conservation and environmental benefits. In the course of this work, we have accepted challenges that are so difficult, there are sometimes no other qualified sources in the world.

Spencer has spent more than a century developing effective solutions and systems for air and gas handling. Some examples:


Corrosive, flammable and toxic gases

Difficult-to-handle gases such as sulfides, halogens, acids, flue and stack gases, cyanides and ammonia may require custom designed blowers, special metals, protective coatings and other provisions capable of:

  • Temperatures to 1100°F
  • Housing design pressures to 1000 PSIG
  • Inlet pressures to 300 PSIG
  • Differential pressures to 20 PSIG
  • High-efficiency or hermetic sealing



Spencer blower for potentially unstable acetylene gas has 250 PSIG blower housing, nonsparking internal components, nitrogen-purged control panel and triple-redundant blower protection devices, all prepiped, prewired and skid-mounted for convenience.


Landfill gas and digester gas boostersSpencer is a leader in this new technology that recovers potential environmental pollutants from anaerobic digesters and municipal landfills and turns them into valuable alternative energy sources.



Digester gas booster system, delivered as a complete module including controls, has all-stainless-steel components to withstand highly corrosive gas, plus an integral moisture separator to deliver drier, cleaner fuel.


Innovative “vacuum utility” systems

Spencer mobile and stationary vacuum systems have wide and customizable capabilities far beyond dirt pickup. They can collect recyclable or waste materials, hold down or pick up production-line components, scavenge fumes, remove solid and liquid spills, work with vacuum-assisted shop tools and clean up everything from shredded vegetables to gravel. The proper system for you may be a single user mobile vacuum unit, a multiple user skid-mounted package or a building-wide system complete with custom collectors, controls, tubing network and vacuum tools.



Large Spencer central vacuum system evacuates laser surgery smoke from hospital operating rooms using three multistage centrifugal vacuum producers, galvanized wet separator, secondary HEPA filter and vacuum tubing network.


Compact regenerative blowers

Spencer’s Vortex® regenerative (side channel) blowers are especially suited for printing, food and chemical processing, metalworking, industrial waste treatment and aquaculture applications, where they offer compact size and reliability. For Original Equipment Market convenience, Spencer can make a variety of modifications: different surface treatments, inspection ports, alternative motors, custom labeling and various metals of construction—whatever it takes to make our blowers compatible elements of your products.



Vortex blowers for commercial vegetable washing equipment have special stainless steel bases, washdown motors and epoxy paint for cleanliness in this OEM food processing application.
