Top Quality Ceramic Air Diffuser.Probably the only air diffuser you will ever need to buy - producing micro-fine bubbles. This is a solid Carborundum porous stone (not resin bonded granules).

It creates minimum back pressure, therefore can be run by a low pressure pump (over 20ltrs/min). Could even be used with our 45ltr air piston pump which only uses a max 25w. Approx 9" diameter Self weighting (1.5kg) 8mm Stainless Steel barbed inlet Suitable for 5mm - 10mm pipe.
