Sweetwater Oxygen Diffusers

Divide the total oxygen flow your system needs by the per-diffuser rate — 9 LPM for AS80, 14 LPM for AS150 or 28 LPM for AS300.

AS80 takes 9 LPM, AS150 takes 14 LPM and AS300 takes 28 LPM.

Same glass-bonded silica body, but a smaller pore size that gives finer, more uniform bubbles for oxygen service.

Yes — about 5 inches H2O more than a standard Sweetwater air diffuser.

You can, but the finer pores add pressure and maintenance, so the standard Sweetwater air diffusers are the better choice for plain aeration.

All three models use a 1/4″ (6 mm) hose barb.

More than standard diffusers — the fine pores need cleaning more often to keep the bubble pattern even.

Fine-pore bonded silica diffusers for dissolving pure oxygen into tanks and holding systems.

Product Information

Same glass-bonded silica construction as Sweetwater air diffusers, with a smaller pore size
Finer, more uniform bubbles for highly efficient oxygen dissolution
Three models — AS80, AS150 and AS300 — covering 9 to 28 LPM
All models fit a 1/4″ (6 mm) hose barb
Built for pure oxygen gas service rather than general aeration
Needs roughly 5 inches H2O more pressure than a standard Sweetwater air diffuser
Fine pores need more frequent cleaning than standard diffusers — plan the maintenance in
Sizing — divide the total oxygen flow your system needs by the per-diffuser flow rate in the table below to get the number of diffusers.

Model	Gas flow	Size (length × Ø)	Gas connection
AS80	9 LPM	8 cm × 4 cm	1/4″ (6 mm) hose barb
AS150	14 LPM	15 cm × 4 cm	1/4″ (6 mm) hose barb
AS300	28 LPM	30 cm × 4 cm	1/4″ (6 mm) hose barb
