    Setup and function Description of components Drive unit The partial vacuum in the wet separator is generated by 2 single-phase AC blowers. Liquid container The liquid container (8) (max. capacity 7 ltr) is located at the rear of the wet separator. The liquid container can be removed for filling and emptying.
  • Page 24 Setup and function Moisture separator The housing of the moisture separator is located on the liquid container. The moisture separator separates small droplets of liquid and residual particles from the vacuumed up medium. The moisture separator can be removed for cleaning. Filter 3 filter cartridges are located above the moisture separator.
  • Page 25 Setup and function Degasification valve The degasification valve is fitted on the cover of the wet separator. Depending on the medium that is vacuumed up, flammable gases may be evolved in the wet separator. These are discharged into the atmosphere via the degasification valve. During vacuum operation the spring-loaded degasification valve is kept closed by the partial vacuum.
