DRYVAC DV 300

Dry compressing screw vacuum pump

 

Smart engineering for today and tomorrow: our network-capable DRYVAC series delivers cutting-edge performance and efficiency, even when the going gets tough.

This series of dry compressing screw-type vacuum pumps is engineered for the new era of smart manufacturing. Packed with intelligent features and functions, all DRYVAC models offer seamless connectivity, networked control and superior efficiency.

DRYVAC pumps boost your productivity, minimize your carbon footprint, and lower your costs. Plus, thanks to an integrated smart service concept, they virtually look after themselves.

Connected, efficient, reliable – smarter with Leybold.

 

Built-in intelligence for industrial applications

Seamless connectivity & networkingSeamless connectivity & networking
Fieldbus and PLC compatibility allow for connectivity to other devices in a network for real-time communications and control. Direct control is also possible via a computer or handheld device. Support for various fieldbus protocols ensures maximal flexibility. Protocol support for Profibus, Ethernet/IP, ProfiNet and EtherCAT as option.

Intelligent energy consumptionIntelligent energy consumption
Exceptionally low constant power consumption delivers world-class energy efficiency. The advanced self-regulating feature, only consumes the power the pump actually needs, saving costs and reducing your carbon footprint. DRYVAC pumps are more cost-efficient and greener than similar models operating in the low-pressure range (<10 mbar).

Smart service conceptSmart service concept
Continuous performance monitoring made possible via an integrated frequency converter and three independent sensors. Should abnormal conditions such as overheating be detected, DRYVAC pumps can communicate them quickly and efficiently via fieldbus. Preset parameters enable plug-and-play operation, without additional installation.

DRYVAC pumps also feature minimal maintenance and easy cleaning of water cooling channels thanks to a non-jacketed design.

 

Characteristics

  • Hermetically sealed screw vacuum pump with integrated frequency converter

  • Simple mechanical and electrical integration

  • Integrated protection functions of temperature, exhaust pressure and power consumption monitoring

  • Small footprint due to compact design

  • Low energy consumption achieved through optimized rotor geometry and innovative motor design with efficiency class IE3

  • Tolerant to dust ingress

  • Excellent condensable gas (water vapor) performance

  • High pumping speed also at high intake pressures
