Summit Dynamics, Inc. distributes regenerative and centrifugal blowers, as well as air knife systems, manufactured by Republic Sales and Manufacturing. The following charts, specifications, blowers, and components are manufactured by Republic.
Republic Sales and Manufacturing's Centrifugal and Regenerative Blowers are used for a variety of reasons: to improve product quality; to reduce operating costs; to provide machine portability; to free compressor capacity. Often, installing a blower for one reason gains multiple benefits, producing better quality at a lower operating cost.

Characteristics and Advantages of Blowers: Blowers are used to produce large volumes of air at lower pressures as compared to compressed air. Although there are some applications where compressed air is necessary (air cylinders, pneumatic tools), a large number of industrial applications can use either compressed air or air generated by blowers. For applications where either compressed air or blowers will work, blowers have several advantages over compressed air. First, blowers are efficient. For a given volume of air, operating cost of a blower is a fraction of the cost of using compressed air. (for savings examples see the cost saving calculator) Second, blowers provide clean air. Since blowers do not use oil as a lubricant, there is no danger of oil droplets or residue in the blower air stream. Because air pressures are less than compressed air (and thus not as prone to cooling due to air expansion), the exhaust is also free of condensate. This eliminates the need for standard oil and water filters (and the maintenance and parts required) normally found on compressed air systems. Third, blowers are deployed independently. There is no need for high pressure piping, drop lines, or concerns about pressure drops due to distance from compressor. Since blowers are independent of each other, shutting down one will not affect the operation of others. Blowers excel at producing large volumes of air needed for many industrial drying, cleaning, ventilation and vacuum applications. When searching for a blower, whether regenerative or centrifugal, look for these characteristics: blower should match the application requirements; it should be reliable; and it should be easy to maintain and service.
Regenerative blowers, also know as Ring blowers, Vortex Blowers or Side Channel blowers, provide greater pressure than fans. Uses for regenerative blowers include: drying, aeration, mixing, vacuum, ventilation, and material transfer. Specific examples of applications include: mixing sediment; aeration of chemical tanks; aeration of fish farms; drying; pneumatic conveying and transfer (air tubes); card and paper stock feeding; air bearings; waste collector (both wet and dry); trim removal (slitting lines); bottling (pressurizing and air vacuum for quicker fill time); dust removal (pressure and vacuum); fluid circulation; vacuum material transfer (via suction cups); removing static electricity from plastic containers; and air replenishment. Centrifugal Blowers generate greater pressure and volume than regenerative blowers. Uses for centrifugal blowers include: bottle and can drying; conveyor and sheet drying; conveyor debris removal; stamped parts drying; plastic drying; food processing; landfill gas removal; industrial vacuum applications; and parts conveying. The following factors need to be considered when designing a blower system: target composition and speed of movement; the distance from the air knife or nozzle to the target; and the distance between the blower and the air knives. Certain situations require compressed air (high pressure, low flow - i.e.
pneumatic cylinders, air driven tools, paint sprayers); but most drying
applications are well suited for high volume air provided by blowers.
Blowers are efficient, less expensive to operate, more easily deployed, and have
lower maintenance costs than large compressors. In addition, air flow
generated by blowers has several inherent advantages over compressed
air: Blowers can be used with or without air knives. Blowers generate air pressure and volume, air knives efficiently direct the air flow at the target. When considering an application involving both blower and air knife, the two must be specified in conjunction with each other in order to accomplish the greatest benefit.
