Edwards EPX 180LE High Vacuum Primary Dry Vacuum Pump 208 VAC 3PH. 3/8 in. Water Connector ISO 63 Inlet. Part Number A41943012 - Without TIM

The compact EPX180LE without Tool Interface Module (TIM) high vacuum drypump offers enhanced performance with reduced cost of ownership. Using a unique patent protected mechanism the EPX180LE is capable of pumping from atmosphere to ultimate pressures of less than 7 x 10-5 Torr. These are truely amazing pumps; the Edwards EPX pump can pump down from atmosphere to the turbomolecular pressure range and can operate continuously at all inlet pressures. Based on the successful award winning IPX range, the modular EPX180 offers outstanding performance in a package that is 20% lighter, 30% smaller and requires 40% less power than the IPX. The EPX LE series of pumps has an End User Controller (EUC). The End User Controller enables local control for stand-alone use as well as the ability to connect to a fab-wide network for remote control and monitoring. The EPX pump system operates at pressures between atmospheric and ultimate vacuum, with no lubricating or sealing fluid in the pumping chamber. This ensures a clean pumping system without back-migration of oil or fluid into the system being evacuated. The EPX 180LE is a good replacement option for the discontinued EPX 180NE model, part number A41944012.

The stator of the pump and the enclosed motor are cooled by an integrated water cooling circuit. The EPX pump is therefore suitable for applications in cleanroom environments where fan cooling is unacceptable. The cooling water supply and return pipelines are connected to the pump by water connectors (customer specified). Cooling water must commensurate with the environmental conditions (humidity and temperature) such that the dewpoint is not reached. The pump incorporates an EMC supply filter and an inverter drive, which provides and controls the electrical supply to the pump-motor. LEDs on the front cover identify the status of the EPX pump. Motor speed depends on the pressure at the pump inlet. When the pump is started with the inlet pressure at or close to atmospheric pressure, the motor accelerates to a speed which is limited by the current which can be supplied by the inverter drive. As the pressure at the inlet is reduced, the motor speed increases, until it eventually reaches its preset maximum speed. If the pressure at the inlet increases, the motor will slow down again.

The EPX LE series of pumps can be manually operated using the End User Control (EUC) local display and keypad, or remotely using a Pump Display Terminal (PDT), if fitted; it can also be controlled and monitored over the network, which connects to the EPX pump through the Network connector. When the EPX LE series of pumps is controlled via the Tool Interface Module (TIM), the EUC simply monitors the status of the pump. The EPX pump is compatible with Fabworks 32. The EPX has four vibration isolators. Pump protection sensors automatically shut down the pump if a fault condition arises. The EPX series covers a broad range of applications from wafer handling through to medium duty processes. The EPX ‘LE’ Series has been designed for use in clean duty applications pumping inert gas mixtures, such as loadlock, whereby control is provided by the process tool interface.
