This is a series of adjustable flow rate single stage vacuum pumps particularly good for use in high contamination areas where dust and small debris is likely to enter the vacuum line. The design of this pump enables particles and small debris to pass directly through the pump. High flow rates can be achieved in conjunction with vacuum levels down to -85 kPa while maintaining a high performance to air consumption ratio.
