KRF04A-P-G1 Oil Free Rotary Vane Vacuum Pump

Model Item / SKU

krf04a-p-g1

This model is part of the United States catalog.

Our KRF04A-P-G1 model KRF Series Rotary Vane Pump delivers vacuum to 7.3 in. Hg with flows to 2.65 CFM. Its self-lubricating sliding vane technology eliminates oil from the compression chamber entirely, delivering a clean, contaminant-free airstream suitable for healthcare, food contact, and precision process applications where oil contamination is not acceptable. The KRF Series handles both vacuum or pressure in a single unit, up to 78 CFM, 20 in. Hg continuous vacuum, and 10 psig continuous pressure, reducing the number of machines required in mixed-mode installations. An integrated inlet filter, vacuum regulator, and combined vacuum/pressure gauge are included as standard. With no oil to change and self-lubricating vanes, the KRF requires significantly less scheduled maintenance than lubricated rotary vane alternatives, making it a practical choice for facilities focused on uptime and reduced maintenance overhead.

KRF Highlights

  • Oil-Free Operation: Self-lubricating sliding vane technology delivers a clean, contaminant-free airstream with no oil in the compression chamber, suitable for healthcare, food, and sensitive process applications
  • Vacuum or Pressure Capable: Operates at continuous vacuum (to 20 in. Hg) and continuous pressure (to 10 psig) modes, a single unit covers a wider range of application requirements
  • Positive Displacement Design: Consistent, pulse-free performance across the full operating range, output is stable from startup to full load
  • Less Maintenance: Oil-free sliding vane design eliminates oil changes and oil filter replacements required by lubricated units, vane life is 4,000–6,000 operating hours depending on application
  • Integrated Inlet Filter and Vacuum Regulator: Protects the pump from particulate ingestion and allows vacuum level adjustment without external components
  • Integrated vacuum or pressure Gauge: Operating conditions visible at a glance, no additional instrumentation required
  • Motor Mounted: Compact, direct-drive configuration reduces footprint and simplifies installation
  • Air-Cooled Design: No water cooling required, suitable for temperature-controlled environments and simple installations
  • Robust Construction: Designed for heavy-duty, continuous operation in demanding industrial and automation environments
  • Application Focus: Medical suction, sterilization, surgical suction, thermoforming, autoclaves, pick and place, and vacuum lifting
