High-Shear Oxygen Nanobubble Generator
X-MN-300Y is an integrated oxygen nanobubble generator featuring gas-liquid shearing technology and a built-in high-purity oxygen concentrator (93±3% O₂). It delivers adjustable bubble concentration and size, achieving dissolved oxygen levels >40 mg/L—4-5 times higher than conventional methods. Ideal for aquaculture oxygenation, advanced oxidation processes (AOPs), and lake remediation.
Product Overview
The Gas-Liquid Shearing Oxygen Micro/Nano Bubble Generator represents a significant advancement in bubble generation technology. Building on the conventional 300W model, this enhanced version integrates a high-concentration pure oxygen machine, enabling dissolved oxygen levels to reach over 40 mg/L—far exceeding saturation levels achievable with air or standard oxygenation methods.
As a advanced Micro Nano Bubble Generator, this system utilizes gas-liquid shearing technology to produce ultra-fine bubbles with exceptional density and stability. The integrated oxygen concentrator ensures a continuous supply of high-purity oxygen, making it ideal for applications demanding extreme oxygenation, such as intensive aquaculture, advanced oxidation processes, and lake remediation.
With adjustable bubble concentration and adjustable intake flow rate, researchers and engineers can fine-tune performance to match specific requirements. The multi-gas source mode optional feature provides flexibility to switch between oxygen, air, or custom gas mixtures—all within a single, compact unit.
Whether you need a High-Shear Mixing Aerator for wastewater treatment or a Hydrodynamic Cavitation Reactor for advanced oxidation research, this generator delivers consistent, high-performance results.
Key Features
💨 Integrated High-Concentration Oxygen System
The standout feature of this Gas-Liquid Dispersion System is its built-in oxygen concentrator. Unlike units requiring external oxygen supplies, this generator produces high-concentration oxygen on-demand, ensuring consistent performance without the need for gas cylinders or external generators. Dissolved oxygen levels routinely exceed 40 mg/L—ideal for oxygen-intensive applications.
🔧 Multi-Gas Source Mode Optional
Flexibility is built into every unit. While the integrated oxygen system handles most applications, the multi-gas source mode optional feature allows connection to external gases such as ozone, CO₂, or custom mixtures. This transforms the unit into a versatile Venturi Bubble Generator suitable for diverse research and industrial needs.
🎯 Adjustable Bubble Concentration
Fine-tune bubble density to match your specific application. From sparse microbubbles for gentle aeration to high-concentration nanobubbles for aggressive oxidation, this Micro Nano Bubble Diffuser puts control at your fingertips.\
⚙️ Adjustable Intake Flow Rate
Precise control over gas intake allows optimization of bubble characteristics and oxygenation efficiency. Whether you need rapid oxygen transfer or sustained nanobubble persistence, the adjustable flow rate delivers.
🔬 Gas-Liquid Shearing Technology
At the heart of this High-Shear Mixing Aerator is our proprietary gas-liquid shearing mechanism. By subjecting gas-liquid mixtures to intense hydrodynamic forces, we generate bubbles in the micro and nano range with exceptional uniformity and stability.
🌊 Hydrodynamic Cavitation Effect
The shearing process induces hydrodynamic cavitation, generating localized hotspots of extreme temperature and pressure. This enhances chemical reactions—particularly valuable for Advanced Oxidation Water Treatment applications.
📦 Compact, Self-Contained Design
Unlike systems requiring separate oxygen generators, pumps, and controllers, this unit integrates everything into a single, portable package. Plug in power, connect water, and begin generating high-concentration oxygen nanobubbles immediately.
