Ideal for large plants with 4 to 60 technicians working at the same time. The 15HP to 150HP centrifugal multi-stage pump can be set at various vacuum levels from 5" HG (68" water column) for relatively short pipe runs, to 10" HG (135" water column) to offset friction losses on relatively long pipe runs, or to enhance the pick-up of heavy materials. Airflow ranges from 400 to 5,000 CFM. The unique Eurovac design includes special arrangements that make our pumps more efficient than most competitive brands on the market. The standard Eurovac III system is supplied with cartridge filters, automatic compressed air PulseJet cleaning and primary cyclonic pre-separation. Eurovac's industrial-grade induction motors have a 20,000 hour rating.
