microStar Overview

Hammer-rotation

The patented hammermill rotation technology redefines nanobubble generation by eliminating the need for high-pressure pumps. A motor-driven shaft with precision-mounted hammers spins at 3,400 RPM inside a vertical tube, crushing injected gas into ultra-fine nanobubbles through mechanical shearing—not hydraulic force.

No turbulence

Water and gas enter from the top, while hammers at the shaft bottom dissolve and fragment gas molecules into high-concentration nanobubbles with zero turbulence. Because the system doesn't circulate large volumes of water or require pressurization, it delivers the lowest energy consumption per nanobubble in the industry. Think of projects like washing eggs to remove bacteria or bacteria bed filters, which should not be disturbed but require adequate amounts of gas.

The microStar series leverages this hammermill design for ozone gas applications and harsh environments like seawater treatment, where corrosion resistance and energy efficiency are critical. Contact us for more details about this unique product. Currently, we have three sizes available. The smallest unit is ideally suited for research purposes; the two larger units can be used for production purposes.

Frequently Asked Questions

  1. What is the microStar Ozone nanobubble generator?

    The microStar Ozone is a motor-driven nanobubble generator that uses patented magnetic hammer-rotation technology to crush ozone gas into ultra-fine nanobubbles without requiring high-pressure pumps. Hammers mounted on a shaft rotate at 3,400 RPM inside a vertical tube, mechanically shearing gas into nanobubbles with zero water turbulence—ideal for applications like egg washing, bacteria bed filters, and advanced oxidation processes where flow disturbance must be minimized.

  2. How does magnetic hammer-rotation differ from pump-based nanobubble generators?

    Unlike traditional systems from Acniti and Competitors that rely on pressurized water pumps ranging from 15–120 PSI, the microStar uses a low-energy motor (30W–750W) to generate nanobubbles through mechanical hammer impact. This eliminates the need for high-flow water recirculation, reducing energy consumption by up to 70% compared to venturi or vortex pump systems. The hammer-rotation method also produces zero turbulence, making it suitable for delicate biofilm applications where pump-driven agitation would damage biological filters.

  3. What power options are available for the microStar Ozone?

    The microStar offers four motor configurations: ​

    • 30W model: Research labs and benchtop testing
    • 150W model: Small-scale production (pilot systems)
    • 400W model: Medium industrial applications
    • 750W model: Large-scale water treatment facilities
    All models are available in AC (100–110V or 200–220V) and DC (200–220V) versions. DC models deliver higher nanobubble concentrations due to more stable motor performance.

  4. Does the microStar require high water pressure to operate?

    No. The microStar operates at ambient pressure (no pressurization required), unlike competing nanobubble systems that demand 5–8 bar (72–116 PSI) to function. This eliminates the need for expensive high-pressure ozone generators or ozone compressors—common cost barriers in traditional ozone nanobubble setups. Water enters the top of the unit via gravity or low-head feed (0.5–1.5m head), making installation simpler and safer.
