CPT cone De-Airing System

The Feritech CPT cone de-aerator is designed to remove air and fully saturate the pore sensor and filter to give a much improved pore pressure response. Our cone de-airer can be used  with any brand of geotechnical cone.

The system uses a vacuum pump to evacuate the cylinder containing the cones, this causes the glycerine or silicon oil to fully saturate any air space within the pore sensor.

The system is built into a rugged steel (or stainless steel) frame and can be supplied in a weather proof enclosure for use out doors. We can also offer a compact unit for use inside CPT vehicles.
