Product features

  • Single-stage liquid ring element → handles wet vacuum applications
  • 30–500 m³/h range → helps size smaller process systems
  • Once-through option → enables straightforward liquid supply design
  • Partial recirculation → allows adapted liquid consumption
  • Total recovery option → enables more complete seal-liquid reuse
  • Multiple mounting configurations → ease mechanical integration
  • Tolerance of vapor and liquid carryover → supports wet processes
  • Flat port plate arrangement → suits the specified vacuum operating range

Product description

Atlas Copco AWC / AWC A is a series of single-stage liquid ring vacuum pumps intended for extrusion, degassing, filtration, drying and wet process duties. Vacuum level, gas composition, moisture load and changing capacity requirements influence both operating reliability and total lifecycle cost. Selection should therefore begin with the actual duty point and the conditions at the pump inlet.

The series uses single-stage liquid ring element with multiple sealing-liquid recirculation options. This construction addresses the process duty by providing a defined pumping principle and an arrangement that can be integrated into the plant. The operating effect and service requirements must be evaluated for the selected size and configuration rather than assumed for the entire range.

Atlas Copco lists 30–500 m³/h and once-through, partial-recirculation and total-recovery configurations. Confirm achievable pumping speed and ultimate pressure at the specified operating point; maximum figures are not necessarily concurrent. Review utilities, exhaust management and any relevant process-media restrictions before ordering.

For operations and maintenance teams, attention to pump sizing, controls, installation access and planned service helps reduce avoidable interruptions. AxFlow can support product selection, discuss maintenance and spare parts, and help identify the appropriate version. Contact AxFlow to confirm suitability, availability and a quotation.


Atlas Copco AWC / AWC A is designed for extrusion, degassing, filtration, drying and wet process duties. The relevant duty point depends on the vacuum level, gas load and operating conditions. AxFlow can help identify an appropriate pump configuration.
The series uses single-stage liquid ring element with multiple sealing-liquid recirculation options. This determines how the pump generates vacuum and what utilities it may need. Review the selected model documentation for the detailed design.
Atlas Copco lists 30–500 m³/h and once-through, partial-recirculation and total-recovery configurations. Verify required suction capacity and pressure at your actual process conditions. Ask AxFlow for model-specific technical documentation before final selection.
AxFlow provides product selection and service support for its supplied equipment. Spare parts must be matched to the exact pump version and serial information. Contact AxFlow to confirm the required parts and availability.
Specify required vacuum pressure, inlet flow, gas composition and operating pattern. Also state installation conditions and any relevant moisture or liquid carryover. AxFlow can review these requirements and provide a quotation.
