20Ltr De-Airing Tank - SL635

20Ltr De-Airing Tank

When the de-airing tank is connected to the vacuum pump, it produces de-aired water, used to measure pore pressure.

The de-airing tank consists of a perspex cylinder fitted with a water spray inlet, an air outlet and a water outlet in the lower part of the tank. A vacuum supply is connected to the air outlet and water is sucked into the cylinder in a fine spray via the water inlet. The vacuum de-airs the water .
