Edwards vacuum pumps, series EM operate the Oil Sealed Rotary Vane system, which is a vacuum pump that provides high suction values, fast, quiet sound, suitable for use in science laboratories. And general industry The operation of the machine is highly flexible, able to be used with Single-phase or Three-phase lights.
