Extruder Degassing
By mixing and melting at high temperatures, various gases distribute uniformly from plastics. Kinney A Series vacuum pumps pull vacuum from extruder vents to enhance devolatilization efficiencies. A Series pumps can be offered as water-sealed or oil-sealed. KVA series rotary vane pumps are also offered for this application. The typical vacuum requirement for extruder degassing is 23 to 26” Hg.
