Standard De-Airing Water System

Description

De-airing the water, that will be used to fill triaxial cells, pressure systems and volume change measurement apparatus, is essential for properly saturating soil specimens.
The system comprises the following:
- A de-airing tank (two versions are available with 7 or 23 L capacity)
- Vacuum pump with air drying unit
- Valve panel

- Tubing and accessories

De-airing tank 

The tanks consist of a transparent acrylic cylinder fitted with a water spray inlet, an air outlet, a water outlet and a metal stand which can be wall-mounted at a suitable level to fill the triaxial system by gravity. teo model are available 7 and 23 l capacity.

Vaccum pump with drying unit 

The vacuum pump 86-D2001 has to be used with the air drying unit (86-D2005) filled with silica gel desiccant (86-D0819). This is recommended to avoid/limit water vapour mixing with the oil in the pump, which, in significant concentrations, may cause serious damage to the pump. When the pump will be used intensively, use of the outlet mist filter (86-D2001/3) is also recommended, which collects any oil vapour issuing from the oil reservoir during operation.


Valve panel 

This panel controls the water going in and out of the de-airing tank. For connecting the de-airing tank to the vacuum pump. Includes water tap connection and two de-aired water outlets.
The valve panel, 28-WF4225, is usually affixed to the laboratory wall directly underneath the de-airing tank at a suitable height to be operated by hand.
