Rotary vacuum pumps


Turnkey solutions for industrial vacuum applications

  • Our rotary screw vacuum pumps feature a SIGMA profile airend specifically designed for vacuum applications such as hold down for CNC router tables, vacuum forming, thermoforming, packaging, bottle and tube filling, drying, degassing, and filtration.

  • Volume: 166 to 551 acfm
  • Final vacuum: 99 %
  • Pressure range: 10-29" HgV

Your advantages

  • Extremely efficient:
    IE4 motors
  • Quiet operation:
    Soundproofing and vibration isolation mounts ensure low noise levels and smooth, quiet operation.
  • Easy installation and service-friendly:
    All units arrive piped and wired, ready for installation. Wide-opening doors and a removable rear panel facilitate easy access to all maintenance components.
Reduza seus custos operacionais
Custo da vida útil

O sistema de acionamento por correia em V,com tensionamento automático, aciona o compressor precisamente na velocidade correta. A potência do motor é transmitida ao compressor da forma mais eficiente possível, economizando energia e melhorando a confiabilidade do conjunto.
