LUBRICATION
OIL COOLER, OIL FILTER & SEPARATOR
COMPRESSOR OIL SYSTEM
(Figure 5-1) The compressor oil system cools the compressor, lubricates
moving parts and seals internal clearances in the compression chamber.
Air pressure in the oil reservoir forces oil through the oil cooler, thermostatic mixing valve, oil filter and into
the compressor main oil gallery.
The oil passes through internal passages for lubrication, cooling and sealing. The air-oil mixture is then
discharged to the oil reservoir where a large part of the entrained oil drops out of the air stream. The
remaining mixture then passes through the final oil separator where most of the remaining oil is removed.
The air then passes to the aftercooler. The oil separated from the air is sent to the oil cooler and
recirculated throughout the system. Oil separated at the air/oil separator is sent via an oil return line
through an orifice and back into the compressor.
RECOMMENDED LUBRICANT – Gardner Denver compressors are factory filled with AEON lubricants.
These lubricants are formulated to the highest quality standards and are factory authorized, tested and
approved for use in rotary screw compressors. AEON lubricants are available through your authorized
Gardner Denver compressor distributor.
