The 220 Volt Pumps have the same specifications as the 110 V pump with the following difference:
- They are Dual Voltage Dual Cycle (110 V/60 Hz and 220 V/50 Hz) and come equipped with both US 110 V and 220 V cords that plug into the back of the motor and a switch to easily switch between voltages.
Good vacuum practice calls for the hose connections to be as short as possible to achieve ultimate vacuum. A gas ballast helps purge moisture from the vacuum system. The gas ballast valve, oil-level gauge, inlet and outlet connections, oil fill plug and drain are all easily accessible. A trap reduces the risk of oil being drawn back into the system.
