Drum Blower Series D807 / D907 – Bi-Lobe Dry Bulk Truck Blowers

In 1980, innovation was achieved when the D800 was introduced to the United States from the Gardner Denver United Kingdom facility. In 1991, the evolution of the product continued with the introduction of the D807 as the first straight-lobe blower to deliver up to 18 psi and 17 inHg.

Perfection was achieved in 1997 when the D807 became the first straight lobe blower to achieve 20 psi continuous pressure. In that same time period, the diamond shape discharge port was implemented to help in reducing overall noise, along with added cooling fins and reinforced ribs to increase strength of the unit. 

Fitting a D807/D907 on your tractor means it will be ready to do any job necessary. Keep your fleet size in control and make dispatching easy.

 

  • D807 Airflow up to 1030 CFM and pressure capability up to 20 PSIG 
  • D907 Airflow up to 1319 CFM and pressure capability up to 16 PSIG 
  • Vacuum performance up to 17 inHg 
  • High airflow across a wide speed range 
  • Oil-free rotor housing chamber
  • Diamond-shaped discharge port for reduced noise 
  • Dual splash lubrication for increased reliability 
  • Reinforced ribs and cooling fins for strength and lower operating temperatures 
  • Cast iron headplates for rigidity and corrosion resistance 
  • High-Pressure Capability

D807 is the first straight-lobe blower in its class to achieve 20 PSIG continuous pressure, ideal for demanding dry bulk applications.

  • Versatile Performance

Wide operating range supports loading and unloading of powders, grains, fodder, and granular materials.

  • Noise Reduction Design

Diamond-shaped discharge port geometry helps reduce overall noise levels during operation.

  • Durable Construction

Reinforced ribs, cooling fins, and cast iron headplates improve structural integrity and long-term durability.

  • Service-Friendly Design

Identical impellers and drive shafts simplify installation, service, and spare parts management.

  • Proven Reliability

Backed by more than 40 years of field-proven performance and continuous product evolution.

The Drum Series D807 / D907 is well suited for a wide range of dry bulk pneumatic conveying applications, including:

  • Cement and lime
  • Sand and aggregates
  • Sugar and food-grade granules
  • Pebble lime
  • Plastic pellets
  • Agricultural products and feed
