3.2 LUBRICATION AND APPLICATION GUIDE
Refer to Figure 3-1. Sullair Rotary Screw Vacuum
Systems are supplied factory-filled with SRF (or
optional fluid of Sullube), which is suitable for most
operations and ambient conditions. Under abnor-
mal operating conditions such as high operating
temperatures, high humidity gases, high gas
stream particulate levels or when the gases han-
dled are corrosive or oxidizing, the fluid should be
changed more frequently.
SRF fluid may not be compatible with certain corro-
sive or oxidizing gases. Consult Sullair for lubrica-
tion recommendations in such cases.
When handling gases saturated with water vapor,
condensed moisture, emulsification may occur. The
lubricant must be changed when this condition
exits. If these operational conditions exist, a lubri-
cant with enhanced rust, oxidation and foam inhibit-
ing characteristics, and enhanced water separation
characteristics should be used. Water must be
drained from the fluid sump periodically. Contact
Sullair for a lubricant recommendation.
Also, when ambient conditions are extreme, the use
of "extended" lift synthetic lubricants may be war-
ranted. Contact Sullair for a recommendation.
DO NOT MIX DIFFERENT TYPES OF LUBRI-
CANT. Mixing of different types of lubricants may
lead to operational problems such as foaming or
plugging of filter, orifice and line.
Sullair encourages the user to participate in a lubri-
cant analysis program with the lubricant suppliers.
This could result in a change interval differing from
that stated in this manual.
Sullair standard Rotary Screw Vacuum
Systems are filled with SRF 1/4000 as fac-
tory fill.
Mixing, changing or adding other lubri-
cants within the vacuum unit may void the
air-end warranty.
Before changing or recharging system
fluid always relieve all pressure from the
sump tank and all compressor lines.
Figure 3-1 Fluid Fill Port Location (typical)
Mixing, changing or adding other lubri-
cants within the compressor unit may void
the air-end warranty.
When performing a fluid
change or topping off the fill,
the proper level should be at
half of the lower sight glass
with the machine running.
