Proper lubrication is the key to long life for your blowers. The Roots RAM series utilizes oil on both the drive end and gear end. For more information about the type of oil needed, read more here: Lubrication for Rotary Lobe Blowers
The following oil guidelines apply to the RAM, RAM-J and RAM-GJ series of blowers. Please note, the amounts listed in your manual and on this website are an approximate amount of oil to have on hand for the oil change. When adding oil to your blower, the correct oil level in the oil sump is determined strictly by using the oil sight glass or oil level plug. Make sure you use these indicators so you do not overfill the unit!
