Description
OASE SubFlo Diffuser S is the shallow-water diffuser in the SubFlo range, for ponds, pools and water bodies up to 2 m deep. Placed on the bottom and connected to a SubFlo Base 4 S, it releases air as ultra-fine bubbles along its entire length: oxygen is distributed evenly and the water circulates gently, with reduced energy consumption.
All-in-one: the SubFlo 4 S pack combines the base, 4 S diffusers and the tubing.
How the Diffuser S works
The air sent by the base passes through an extruded EPDM diffuser tubing. Its design distributes the air evenly along the entire length of the tubing: the ultra-fine bubbles come out everywhere at once, which maximises oxygen exchange and water circulation while limiting the energy required. Its robust thick-walled construction ensures a long service life.

Key features
- Evenly distributed oxygen: air comes out along the entire length of the diffuser tubing, for healthy conditions in shallow areas.
- Ultra-fine bubbles: the extruded EPDM tubing ensures optimal gas exchange.
- Energy-efficient: even distribution requires less air to circulate the same surface area.
- Durable: thick-walled construction, resistant to deposits and fouling; stainless steel components.
- Stable on the bottom: supplied empty to reduce weight and shipping costs, it is weighted on site with gravel or sand. A built-in strain relief guides and protects the air tubing.

How many diffusers for my base?
| SubFlo base | Depth | Diffusers |
|---|---|---|
| SubFlo Base 4 S | Up to 2 m | 2 to 4 Diffuser S |
| SubFlo Base 2 D | 2 to 10 m | 1 to 2 Diffuser D (not the S) |
| SubFlo Base 4 D | 2 to 10 m | 3 to 4 Diffuser D (not the S) |
Installing the diffuser
- Weight it on site with gravel or sand.
- Connect it to its own length of weighted tubing SubFlo Tubing H, cut from the 30 m or 150 m roll, which links it to the base.
- Place it on the bottom, spreading the diffusers across the surface of the pond, then adjust their flow on the base's distribution block.
