Oil drain kits
Three types of oil drain kit are suitable for use with the EMF Oil Mist Filters:
z
EMF Clean Application Oil Drain Kits continuously return the oil trapped in the EMF Oil Mist Filter to the
pump. You cannot use a Continuous Oil Drain Kit if you use the pump in processes in which condensible
vapours or sodium azides are pumped.
z
EMF Gas Ballast Oil Drain Kits continuously return the oil trapped in the EMF Oil Mist Filter to the pump.
When fitted, the pump will operate as if the gas ballast control is in position II.
z
EMF Gravity Oil Drain Kits return the oil trapped in the EMF Oil Mist Filter to the pump when the pump is at
ultimate vacuum or is switched off. Oil is not returned to the pump when gas-ballast is on or when the pump
is pumping down to ultimate vacuum. You can continue to use the gas ballast control on the pump when you
have fitted an EMF Gravity Oil Drain Kit.
