Collection: Diffusers

Professional Diffusion Technologies

EPDM Membrane Disc Diffusers

The industry standard for bottom aeration in deep ponds and lakes.

• Self-Cleaning Membrane: Thousands of precision slits open under pressure and self-seal when airflow stops, reducing clogging and sediment intrusion.
• Bubble Size: 1–3 mm fine bubbles for high surface-area oxygen transfer.
• Material Durability: UV-resistant EPDM withstands pH fluctuations, salts, and extreme seasonal temperature changes.

Tube & Linear Diffusers

Designed for large-scale de-stratification and wide-area circulation.

• Best For: Elongated ponds, commercial basins, and high-volume aeration systems.
• Performance Advantage: Even air distribution reduces "dead zones" and improves full water-column mixing.

Ceramic & Micro-Pore Air Stones

Targeted oxygenation for filtration systems and smaller water features.

• Construction: High-fired ceramic or bonded glass media with consistent pore structure for uniform bubble release.
• Applications: Biological filters, quarantine tanks, fish transport, and supplemental aeration points.

Engineering Specifications: Flow Rate & Backpressure

Each diffuser has a defined design flow rate (CFM/LPM). Operating above the rated airflow causes bubble coalescence (bubble merging), which significantly reduces oxygen transfer efficiency. High-quality membranes are engineered to minimize backpressure, protecting your pond aerator from excess heat and premature component wear.

Proper diffuser sizing ensures your aeration system operates within its optimal PSI range while maintaining full-depth circulation.

Installation & Placement Guidelines

• Use a Weighted Base: Keeps the diffuser level and positioned 4–6 inches above the pond floor, preventing sediment suction and clogging.
• Install in the Deepest Zone: Maximizes vertical plume lift and ensures complete water-column turnover (de-stratification).
• Seasonal Maintenance: Inspect 1–2 times per season. If mineral scale develops, clean with a mild citric acid solution to restore original airflow.

High-Performance Gas Exchange for Stable Ecosystems

Our micro-bubble pond diffusers are compatible with standard NPT fittings and weighted airline tubing. By improving aerobic activity and reducing biological oxygen demand (BOD), they provide a chemical-free solution for clearer, healthier water.
