Product Overview
SB-36 Fine-Bubble Pond Aeration Diffuser
The SB-36 Fine-Bubble Aeration Diffuser is an American-made pond diffuser designed for DIY pond aeration systems, small-to-medium ponds, wider coverage layouts, and moderate airflow compressors that need efficient oxygen transfer without excessive backpressure.
The SB-Series uses the same fine-bubble diffuser technology, stainless steel construction approach, and continuous-duty design philosophy as the larger DB-36, but in smaller configurations optimized for precise system sizing. The SB-36 is the next step up from the SB-12 and is ideal when a full-size diffuser would be oversized for the compressor, pond size, or airflow available.
Many small pond aeration systems use air stones, plastic diffusers, or standard membrane disc diffusers that can clog, harden, crack, or create unnecessary backpressure. The SB-36 uses industry-proven Aero-Tube®-based fine-bubble diffuser tubing to produce uniform micro-bubbles along its length while keeping airflow resistance low.
Designed for DIY Pond Aeration
The SB-36 is built for pond owners and installers who need a dual-line fine-bubble diffuser for a DIY or moderate-airflow aeration system. It is well suited for small-to-medium ponds, decorative ponds, farm ponds, shallow water applications, backup aeration, and custom systems using smaller piston, diaphragm, rocking piston, or rotary vane compressors.
Because the SB-36 is optimized for systems above 1 CFM / 30 LPM, it provides broader diffuser coverage while still remaining practical for properly sized DIY and small-to-medium pond aeration systems. Proper diffuser sizing helps maintain bubble quality, system efficiency, and reliable compressor operation.
Fine-Bubble Tubing Instead of Standard Disc Membranes
SB-Series diffusers use high-quality fine-bubble diffuser tubing instead of standard membrane disc diffusers. The tubing produces uniform micro-bubbles along the diffuser tubing, improving air-to-water contact area while minimizing backpressure and reducing the maintenance issues commonly associated with membrane-style diffusers.
Durable American-Made Construction
The SB-36 is manufactured in the USA with stainless steel hardware, stainless base components, a weighted design, a built-in low-pressure check valve, and rugged diffuser tubing selected for submerged continuous-duty pond aeration service.
The SB-36 kit includes:
- SB-Series diffuser assembly, shipped disassembled
- 36 in. total fine-bubble diffuser tubing in a dual-line configuration
- Stainless steel base components
- Stainless steel mounting hardware
- Integrated low-pressure check valve
- 3/8 in. hose barb installed
- 1/2 in. hose barb included for alternate airline connections
Diffuser sizing tip: Use the SB-36 for small-to-medium ponds or low-airflow systems. For more airflow or larger ponds, consider the SB-36, SB-36, SB-36, or DB-36 depending on compressor output and pond layout.
