Product Details

Product Overview

The GB810-3000S is a versatile single-stage side channel blower rated at 3KW (4HP), engineered for mid-range industrial applications that demand consistent airflow and reliable pressure output. With a maximum capacity of 475m³/h and 440mbar pressure, this unit offers an optimal balance between performance and energy efficiency while maintaining oil-free, maintenance-free operation.

Material & Construction

Both the impeller and pump housing are precision-cast from premium-grade aluminum alloy, ensuring exceptional durability, dimensional stability, and corrosion resistance. The refined casting process delivers tight tolerances and a smooth surface finish for vibration-free performance. All motors are wound with 100% copper wire, providing superior electrical conductivity, efficient heat dissipation, and extended operational life.

Working Principle

The side channel blower operates by transferring kinetic energy from a high-speed rotating impeller to the air or gas medium, progressively converting velocity into pressure through a regenerative compression cycle.

  • Intake: Ambient air or process gas enters the side channel through a precision-machined inlet port.
  • Acceleration: The rotating impeller imparts momentum to the gas molecules, propelling them outward via centrifugal force into the specially contoured side channel.
  • Regenerative Compression: The channel geometry causes the gas to recirculate across the impeller blades multiple times before reaching the discharge port. Each pass incrementally increases kinetic energy and pressure.
  • Discharge: Fully compressed air exits through the outlet, typically equipped with a silencer to minimize operational noise.
  • Multi-Stage Option: For applications requiring elevated pressure, two-stage configurations employ a secondary impeller to further compress the gas after the initial stage.
