Description

Can be installed between the vacuum pump (see Vacuum pumps) and the apparatus to be de-aired (e.g. Pyknometers). It has to be filled with a suitable Dessicant (e.g. Silica gel  dessicant 86-D0819). This unit is used to avoid /limit the water vapour to mix with the oil of the vacuum pump, which may cause, as specified, serious damage to the pump when in notable concentration. For more details about complete de-airing systems and the various applications see Additional information.

Specifications

  • Plastic frame with acrylic cylinder
  • Dessicant capacity: 500 g approx.
  • Overall dimensions: 185x300(h) mm approx.
  • Weight approx.: 1 kg (empty)
