Edwards EDS300 – dry screw vacuum pump for industry
The heart of the EDS pumps is a tapered screw mechanism with variable pitch. The EDS300 delivers more than 280 m³/h and reaches an ultimate pressure below 0.01 mbar; at ultimate pressure it draws only 4.5 kW.Features
- Direct water cooling or air cooling (Air Blast) with heat exchanger
- Directly mounted motors for every region
- Simple, robust shaft seal purge system; gas ballast with atmospheric air
- Simple thermal protection; optional enclosure
- Extensive standard accessories
Typical applications
Edwards names lithium-ion batteries, automotive painting, freeze drying, coating of industrial glass, solar cell production, heat treatment, brazing, thin-film deposition, plastics extrusion, pharmaceuticals and renewable energies.Versions of the Edwards EDS300
The 10 versions differ in cooling, mains voltage and frequency. The markets (Europe/USA/China, Asia, Canada) come from the Edwards ordering table.Advice and service
