Product Description
HC - IE3 ASIA 50Hz
New EH500 mechanical booster • Part A30205934
The Edwards EH500 mechanical booster uses a hydrokinetic drive so it can assist pump-down from atmospheric pressure while providing automatic overload protection. This page covers part A30205934.
Features
- Hydrokinetic drive can reduce total pump-down time by up to 50%
- Automatic overload and overheating protection
- No bypass line, pressure switch or inverter required for standard installation
- HC hydrocarbon-oil and FX PFPE-prepared configurations

| Service note | The process chamber is dry. Gearbox, coupling-cover and shaft-seal reservoirs still require the correct lubricant. |
Applications
Mechanical boosters are used to increase pumping speed and reduce pump-down time in industrial vacuum systems. Typical duties include heat treatment, metallurgy, vacuum coating, chemical processing, steel degassing, vacuum drying and large chamber evacuation. Final performance depends on the backing pump and system conductance.
