De-Aired Water Apparatus

 Its compact bench-top design integrates a vacuum-pump interface, sealed de-airing tank, and control valves into a single platform, delivering bubble-free, stable water supply to the cell and the back-pressure systems. This ensures long-term measurement accuracy throughout extended tests. The unit consists of a de-airing tank with transparent level indicator and a flow circuit that degasses water under vacuum. Tank geometry is optimized to prevent bubble accumulation at the water surface; an air-bleed line enables rapid de-airing before testing. The chemically resistant hoses and quick-connect couplings provide direct compatibility with triaxial systems. The configuration ensures stable flow and level control during filling and recirculation. Multiple tank volume options are available (e.g., 7–23 L) to suit laboratory capacity requirements.
