Blowers & Air Handling

Blower Packages

Positive displacement blower packages are provided as a component or as an integral part of a PPS provided system. For over 30 years, we have been providing pressure and vacuum blower packages to the food processing industry.

The blower package, be it a pressure or vacuum system, dilute-phase or dense phase, provides the motive for air delivery of food products through convey lines. Our Process Engineers are able to design blower packages for all compatible applications and provide you with an appropriately sized package for optimum efficiency and performance.

Powder Process-Solutions will customize a blower package for your unique application based on air flow requirements, altitude, and inlet/outlet pressure conditions. Our goal is to provide you with the most economical blower package designed and fabricated specifically for your application.

Dehumidifers & Aftercoolers

Dehumidifiers and aftercoolers are utilized in process air and pneumatic conveying systems to control both the moisture level and temperature of air that comes into contact with moisture and heat sensitive products.


Dehumidifiers use chilled water or refrigerant heat exchange coils to lower the incoming air temperature below the dew point at appropriate face velocities. This allows for the separation of moisture from the air stream followed by the draining of condensate from the housing. Dehumidifiers can incorporate a reheat coil or use heat of compression when located on the intake side of a pressure blower to lower the process air relative humidity for increased moisture carrying capacity.

Aftercoolers use heat exchange coils to remove the heat generated by a pressure blower prior to product contact.

Our superior housing design allows for access to heat exchange coils for inspection and can be arranged in inline or stacked configurations where installation space is limited.

  • 304 or 316  stainless steel and carbon steel
  • USDA Dairy Construction
  • Copper tube and aluminum fin coil
  • O.D. tube, flanged or ferrule connections
  • Insulated housing
  • Temperature and differential pressure gauges
  • Self-acting water flow control valve

Powder Process-Solutions is able to provide custom configurations of dehumidifiers and aftercoolers to fit your equipment, location and plant requirements.

Final Filter

Final filters are the last component in the air stream of a pneumatic conveying system prior to product contact that determines convey air quality. Final filters serve as the sanitary barrier between the process and air handling equipment. A range of filtration efficiencies are offered, including HEPA grade 99.97% efficiency at 0.3 micron suitable for dairy and 3A applications.

  • 304 or 316 stainless steel
  • USDA Dairy construction
  • Removable filter from housing – no tools necessary
  • Varying connections available with differential pressure gauges
Available Options
  • Low pressure drop rectangular housings
  • Stand alone units
  • Compact cartridge filter units

Final filters provide ultra-filtration required for stringent sanitation guidelines. At Powder Process-Solutions, we are committed to providing you the optimal, customized equipment for your specific process.
