Coarse Bubble Tubular Diffuser

Coarse Bubble Tubular Diffusers are used in wastewater treatment applications where mixing and agitation are more important than oxygen transfer efficiency. They are commonly installed in equalization tanks, grit chambers, and pre-aeration tanks to prevent solids settling and maintain uniform mixing. The larger bubbles provide strong upward velocity, which helps in breaking stratification and keeping heavy solids in suspension. Due to their robust design and lower risk of clogging, coarse bubble tubular diffusers are preferred in high-solid, high-fouling, and variable-load operating conditions where reliability and low maintenance are critical.

MOC & Typical Use Case:
• uPVC: Suitable for municipal and industrial wastewater applications with moderate chemical exposure and standard operating temperatures
• SS (Stainless Steel): Ideal for aggressive industrial effluents, higher temperatures, and applications requiring high mechanical strength and corrosion resistance

AIRFIN Quality:
AIRFIN Coarse Bubble Tubular Diffusers are engineered with a strong diffuser body and precisely sized air outlets to deliver consistent air flow and effective mixing. The use of high-quality uPVC and stainless steel ensures excellent structural strength, corrosion resistance, and long service life in demanding wastewater environments. The simple, non-clog design minimizes maintenance while ensuring stable performance under fluctuating flow and load conditions. Each diffuser is manufactured with strict quality control to ensure durability, leak-free operation, and dependable long-term performance.

Powerful mixing where reliability matters most.
