Regenerative Blower

The regenerative blower can be used as either a vacuum or positive pressure machine. This technology typically has one of the lowest upfront costs for vacuum pumps, and also one of the lowest costs for associated maintenance.

Regenerative Blower

Regenerative Blower Products Available

G-BH7 regenerative blower vacuum pump

  • Up to 20,000 hours without maintenance down time.
  • Reliable under the harshest of conditions.
  • Outstandingly low noise levels.
  • The use of a frequency converter mounted directly on the motor or installed separately in a switchgear cabinet can considerably increase compressor capacity without an increase in size.
  • Speeds of up to 6,000 rpm (100 Hz) can be achieved with standard machines.
  • UL/CSA approval for worldwide use.
  • 50/60 Hz voltage range motors.
  • IE3 / Nema Premium motors on request.
  • Available with ATEX certification.

G-BH100

G-BH100 regenerative blower vacuum pump

  • Height and width of approx. 125 mm and a depth of approx. 60 mm.
  • Smallest side channel blower available on the market.
  • Adjustable volume flow of the machines.
  • Robust and built-to-last design.
  • High level of efficiency.
  • Driven via an electronically commuted DC motor.
  • IE regulations do not apply to DC motors.
  • Maintenance-free operation for more than 20,000 operating hours.
  • The operating electronics are a standard feature of the machines which allow infinitely variable control of speed and output of the blower.

G-BH8

G-BH8 regenerative blower vacuum pump

  • Compact design
    The G-BH is about half as large (installed volume) and nearly 60% lighter than a comparable standard machine with the same performance characteristics.
  • Quiet
    Modern sound engineering: only half as loud (78 db(A) versus 84 db(A))
  • Economical
    Cuts costs for: shipping (low weight), packaging (smaller), electrical installation (smaller cross sections and smaller circuit protection devices), electrical energy (high efficiency and good controllability)
  • Flexible
    These units are normally operated with frequency converters. The housing components can be rotated in 45° increments without manifolds and silencers or in 90° increments with manifolds and silencers. Together, both of these features offer maximum flexibility upon integration in the overall system.
  • Regarding IE3
    200 Hz motors which are used in this side channel blower do not fall under IE regulations.

What is the Regenerative Blower Process?

The regenerative blower can be used as either a vacuum or a positive pressure machine. Gas is sucked in through the inlet, and with every rotation of the gas kinetic energy is added. This results in a further increase of pressure along the side channel. Centrifugal force is the impeller blades accelerate the gas outward into the channels and the pressure increases. The side channel then narrows at the rotator, sweeping the gas off the impeller blades and discharging it through the outlet silencer.

Benefits of the Regenerative Blower

With this technology, it makes the vacuum keep noise levels low while in use. It is also pulsation-free, and virtually unaffected by dust and small particles, making it maintenance-free. It also has an adjustable speed via external or integrated variable frequency drives and holds differential pressures up to 434 in. H2O. Regenerative technology is the lowest upfront cost and the lowest associated maintenance cost. 

What to Expect with Regenerative Technology

This technology is typically one of the lowest upfront costing vacuum pumps and is also one of the lowest associated maintenance costs. The one drawback is a relatively low differential pressure when it comes to efficiency. Overall, regenerative technology is good for a wide variety of applications.

Where Can This Technology Be Used?

This depends on the application and process gases present. The Regenerative Blower Pump is great for environmental applications, packaging, dental, plastics, woodworking, laboratory applications, automotive, printing, soil remediation, wastewater treatment, and landfill degassing. Overall, the Regenerative Blower Pump is the perfect low cost and low maintenance technology for your work.
