PCX405-400 Dry Rotary Claw (Large) PCX405-400 Dry Rotary Claw (Large)

Model Item / SKU

pcx405-400

This model is part of the United States catalog.

The PCX405-400 PCX Dry Rotary Claw Pressure Pump delivers pressure to 29.0 psi and flows to 235 CFM. Oil-free, air-cooled, and self-contained with an integrated inlet filter, silencer, and built-in pressure relief valves standard. The PCX delivers high flow at medium pressure without the need to regulate down from higher-pressure compressor technology, in a compact package that requires no water cooling and minimal installation infrastructure. The PCX series reaches up to 30 psi with flows to 353 CFM: oil-free pressure performance suited for pneumatic conveying, aeration, drying, and specialty process applications including 3D printing argon recirculation and oil dehydration. Non-contacting claw produces no internal wear in the compression chamber; gearbox oil changes every 3,000–5,000 hours is the only scheduled maintenance. Inverter-duty rated motors support VFD operation for adjustable output and energy savings. Gas-tight and corrosion-resistant lining options are available for aggressive or specialty gas applications.

PCX Highlights

  • Oil-Free Compression: Non-contacting claws design delivers clean, oil-free compression, eliminating contamination risk to the process airstream
  • Deep Vacuum Capability: Reaches down to 27 in. Hg with flows up to 353 CFM, delivering high vacuum performance in a dry, non-contacting design
  • More Flow Per HP: Delivers more CFM per horsepower than comparable vacuum technologies, reducing energy costs in continuous-duty vacuum applications
  • Built-In Relief Valve: Integrated vacuum relief valve prevents dead-heading without external protection components, standard on every unit
  • Low Noise: Sound enclosure and integrated discharge silencer keep noise levels below 84 dBA without additional acoustic treatment
  • Low Maintenance: Non-contacting claws eliminate internal wear, with gearbox oil changes every 3,000–5,000 hours as the only scheduled maintenance
  • VFD Compatible: Inverter-duty rated motors support variable frequency drive operation for speed control, energy savings, and soft-start capability
  • Air-Cooled Design: No water cooling required, simplifying installation and expanding suitability across temperature-controlled and remote environments
  • Application Focus: Medical suction, central vacuum systems, dental, CNC routing, thermoforming, vacuum hold-down, and vacuum lifting
