Free Standing Air Diffuser Rubber Membrane

If you want serious bottom-level aeration without changing your drain, the Super-Aerator 340 mm Diffusser (Free-standing) AP100 delivers wide, even air coverage from a premium rubber membrane.

This free-standing model uses a 340 mm diameter premium grade diffuser membrane mounted on a sturdy stainless steel base.

Why it stands out

• 340 mm premium rubber membrane for broad air coverage
• 200 mm diameter 316 stainless steel base for strength and stability
• Fitted with rubber feet to protect pond surfaces
• High-quality materials throughout

The wide membrane produces fine, even bubbles, helping improve dissolved oxygen and circulation across the pond floor.

Fit notes

• Suitable for use in ponds with an existing bottom drain where you want independent aeration.
• Place directly on the pond base – rubber feet help protect liners.
• Pair with a suitably rated air pump to match the membrane size.

If you’re converting an existing standard bottom drain into an aerated setup, the bottom drain version (AP101)  is also available.

Maintenance

• Inspect the membrane periodically for blockages.
• Ensure airline connections remain secure and free from kinks.
• Unplug your air pump before servicing any aeration equipment.
