Description

A de-airing water system removes the dissolved air from water  in order to use this water for it soil mechanics tests  (e.g triaxial and permeability) . Wykeham Farrance’s all-in-one unit will de-air water quickly and efficiently down to levels of dissolved air acceptable for geotechnical test methods. 

How it works

• Simply place the De-airing Water Apparatus on a bench and fill the  de-airing tank  with water from the inlet valve.
• Start the de-airing procedure. As the pump applies vacuum to the de-airing tank , the magnetic system will begin to stir the water at high speeds (1000-2000 RPM). Cavitation will then occur allowing water to be de-aired much faster than when only using vacuum.
• Once finished, stop the cycle. The tank will automatically bring the air pressure back to normal, so it is ready to be pumped for filling the triaxial cell, pressure systems and hydraulic circuits. This procedure does not rely on gravity feeding.

High productivity
It takes 15 minutes to produce a 20 liter batch of de-aired water thanks to the smart combination of vacuum pumping and cavitation.

Small footprint
The system can be used on a bench with no need to fit on the wall a separate water tank to fill the triaxial cell.

• SPACE SAVING:  clever all-in-one design with vacuum pump, tank and control valves all integrated into one single unit needing only a small laboratory space.  
• EASY TO INSTALL: turn-key self-pumping system replaces the more cumbersome gravity feed design.
• TIME SAVING: 20 liter batch of de-aired water can be produced in 15 minutes  thanks to the smart combination of vacuum pumping and cavitation.
• ENVIRONMENTALLY-FRIENDLY: diaphragm vacuum pump requires no oil
