Pro-HD Ceramic Diffusers
Pro-HD Ceramic Diffusers
BTA Pro-HD
Ceramic Diffuser
Heavy Duty — High Density — Harmonious Diffusion. Stop settling for fragile, inefficient air stones that compromise your system's performance.
Why Choose Pro-HD
The purity of the raw white aluminium oxide, coupled with high-temperature firing at 1500°C, results in a superior airstone that outperforms sand mineral airstones, black ceramic/corundum, and even heat-bonded silica air stones.
Heavy Duty Construction
Sintered at 1500°C, our diffusers are incredibly strong and resistant to physical shock. Built for the harsh environment of commercial aquaculture and research systems.
High Density Performance
The high-purity ceramic generates a consistent, High Density bubble plume, maximizing air-to-water surface area for superior oxygen dissolution and efficient gas exchange.
Harmonious Diffusion
The optimized pore structure delivers professional results without demanding excessive energy from your blower, creating a balanced, stable, and efficiently oxygenated aquatic environment.
Chemically Inert & Easy to Clean
The high-purity sintered alumina oxide is highly resistant to chemicals and can be easily restored to like-new performance with a standard acid wash, ensuring a long and effective service life.
Professional-Grade Features
Every Pro-HD diffuser is built to exacting standards using materials and processes that ensure consistent performance across thousands of operating hours.
Ultra-Pure Alumina Oxide
White aluminium oxide (Al₂O₃) with exceptional purity ensures no contaminants leach into your water. Unlike black ceramic or corundum alternatives that may contain heavy metal impurities.
1500°C Monolithic Sintering
Extreme-temperature firing fuses particles into a single monolithic structure. No binders, no glues — just pure ceramic strength that resists crumbling and degradation.
Uniform Medium-Fine Pores
Consistent pore distribution across the entire diffuser surface produces an even bubble curtain without dead spots or channelling that plague lower-quality air stones.
Acid-Wash Restorable
Unlike disposable air stones, Pro-HD diffusers can be restored to like-new performance with a standard acid wash. Lower total cost of ownership over years of service.
Wide Flow Range
From 1.0 to 12.0 LPM across the three-model range, there’s a Pro-HD sized for every application — from hatchery tanks to large commercial raceways.
Standard Barb Fittings
4mm and 6mm barb sizes connect directly to standard airline tubing. No special adapters or proprietary connectors required.
Pro-HD Model Range
Three professional sizes to match your system requirements. All models feature the same ultra-pure alumina oxide construction and 1500°C sintering process.
| Model | Dimensions | Barb Size | Recommended Flow Rate (LPM) | Pore Size | Material |
|---|---|---|---|---|---|
| AD504B | 50mm Sphere | 4mm | 2.0 – 8.0 LPM | Medium-Fine | 1500°C Sintered Alumina Oxide |
| AD20504C | 20mm Dia. × 50mm L | 4mm | 1.0 – 4.0 LPM | Medium-Fine | 1500°C Sintered Alumina Oxide |
| AD50506C | 50mm Dia. × 50mm L | 6mm | 2.0 – 12.0 LPM | Medium-Fine | 1500°C Sintered Alumina Oxide |
All flow rates are recommended operating ranges. Diffusers can handle brief excursions beyond stated maximums.
