Lubricant Recommendations
WARNING
AVOID INJURY OR EQUIPMENT DAMAGE!
Use IMT-recommended compressor oil. Inspect and replace oil, air filter, oil filter, and
coalescer elements as stated in this manual.
The combination of a coalescer element loaded with dirt and oxidized oil products together
with increased air velocity as a result of this clogged condition may produce a critical point
while the machine is in operation where ignition can take place and could cause a fire in the
oil sump.
The following are general characteristics for IMT rotary screw lubricant. It is impossible to
establishing limits on all physical and chemical properties of lubricants which can affect their
performance in the compressor over a broad range of environmental influences, so the
responsibility for recommending and consistently furnishing a suitable heavy duty lubricant must
rest with the individual supplier if they choose not to use the recommended IMT rotary screw
lubricant. The lubricant supplier’s recommendation must, therefore, be based upon not only the
following general characteristics, but also upon his own knowledge of the suitability of the
recommended lubricant in helical screw type air compressors operating in the particular
environment involved. The owner of this equipment should contact the factory if IMT rotary
screw lubricant is not used as supplied with this equipment.
CAUTION
We do not recommend mixing different types or brands of lubricants, due to the possibility of a
dilution of the additives or reaction between additives of different types.
