Coarse Bubble Diffuser

The coarse bubble diffuser is a device that generates large bubbles through compressed air to achieve water oxygenation and mixing. Its core structure consists of an ABS material distributor and an umbrella dome and uses multi-layer spiral cutting technology to optimize bubble release. The equipment is widely used in sewage treatment, aquaculture, industrial fermentation, and other fields, especially suitable for deep water environments and high-viscosity liquid mixing scenarios.

Corrosion resistance
The coarse bubble diffuser is made of ABS/nylon composite material. The acrylonitrile segment in ABS gives corrosion resistance, and the nylon amide group enhances the stability of acid and alkali media. In the pH range of 2-12, the Coarse Bubble Diffuser can work stably for a long time, especially suitable for highly corrosive scenarios such as chemical wastewater treatment.

Efficient dissolved oxygen and mixing
The unique multi-layer spiral cutting technology of coarse bubble diffuser enables bubbles to generate spiral convection during the rising process, breaking the water stratification, increasing the dissolved oxygen uniformity by 40%, and increasing the energy efficiency by 22% compared with traditional equipment.

Anti-clogging structure
The nylon parts of the coarse bubble diffuser are ultra-precision polished (Ra＜0.8μm), and the self-cleaning effect of the spiral airflow effectively prevents the attachment of suspended matter, allowing the Coarse Bubble Diffuser to run continuously for 8,000 hours without clogging.

No air filtration required
The air path design of the coarse bubble diffuser can be directly connected to unfiltered compressed air, and its multi-layer spiral structure simultaneously separates impurities while cutting the airflow. The filtration efficiency of particles larger than 5μm is over 90%, and no additional air filter is required, reducing the system complexity by 35%.

No drainage device required
The coarse bubble diffuser uses the arc-shaped diversion design of the umbrella-shaped dome to naturally form a water body circulation during the rising process of bubbles, without the need for additional drainage equipment, which is particularly suitable for scenes with limited space or budget sensitivity.
