Very high-quality aerator plate with a diameter of 107 mm and a height of 19 mm. Suitable for up to 9 litres/minute. The aerator surface (silicon carbide) was baked at 1200 °C in the oven (sintered). Sintered air stones are much more durable and stable than conventional pressed versions. This processing process produces extremely fine air bubbles, which leads to increased oxygen enrichment. The aerator plate is suitable for sea water.
