Products description - Spindrifter Aerator Floor drain 110
The Spindrifter pond aerator consists of an EPDM rubber membrane (diameter 250mm) which is mounted on a plate
made of polypropylene. The aerator is mounted on a stainless steel base and weighs a total of 5 kg.
The Pond Aerator is designed to be installed on the bottom of a pond or filter.
The AeratedDome was designed to be accommodated in an existing ground drain, and the Aerated
Bottom Drain is a complete floor drain with a separate connection for the air hose. If air is supplied to the membrane, no bubbles will be produced initially, but the membrane will be slightly "inflated". When this has reached a certain stage, the bubbles will escape through the 4500 gaps of gradually changing size. When the air supply is stopped, the membrane will "idle", causing the gaps to close before all air has escaped. This prevents water from flowing back into the aerator, preventing clogging and internal contamination.
The required pressure to get the air through the gaps into the membrane is 20mbar at
recommended air supply. The recommended air supply for a Koi pond is 20 litres/min per metre of water Depth per aerator for maximum oxygen input into the water.
