Why?
Why?
Large/small compressors at most calls
Critical application re: production
Compressors & spares are expensive
Energy costs are high & getting higher
LE Compressor Oils really perform

Types of Air Compressors
Compressors are machines for squeezing air
Compressors are machines for squeezing air
(or gas) into a smaller volume
(or gas) into a smaller volume
 There are many types but only 2 main types
are used for compressing air:
Reciprocating & Rotary
 They maybe water or air cooled
 They may range in size from few cubic feet per
minute to thousands of cubic feet per minute
 They range in pressure from few PSI to
100’s PSI

Reciprocating Compressors
 Positive Displacement machines – they increase
the pressure of the air by reducing its volume
 Single stage compressors used for pressures in
range of 70-100 psi
 Two stage compressors used for higher pressures
in range of 100-250 psi

Rotary Screw Compressors
Rotary Screw Compressors
 They are also positive displacement machines
consisting of helically-grooved rotors that mesh
together
 The volume of a trapped mass of air is decreased
along the rotor & the pressure is increased
 Capacity control for these compressors is
accomplished by variable speed & displacement

Centrifugal Compressors (Dynamic)
Centrifugal Compressors (Dynamic)
 They produce high-pressure discharge by converting
angular momentum imparted by the rotating impeller
(dynamic displacement) as illustrated below
 In order to do this efficiently, centrifugal compressors rotate
at higher speeds than the other types of compressors
 They are also designed for higher capacity because flow
through the compressor is continuous

establishing an LE refrigerant oil customer:
 Visual inspection of the lube is the only guide given
as a change out guide by a major OEM – “Change
when discoloured”
 Sample at 3-4 week interval at first to assure lube
integrity
 Sample from bottom of sump if possible to detect
sludge if it is forming
 Use Spectrowear / LEAP Oil Analysis

 Energy consumption is a

 Friction in machines robs

MONOLEC (reduces friction, heat & wear)
 LE lubricants therefore reduce friction & when it is

 Prospects cannot be

LE consultants can create
an image in their minds
with this demo.
 All that is needed is a

 Ask prospect to rub hands
together hard & fast
 Ask what does he feel?
(answer should be friction & heat)
– just like metal surfaces
 Hand him 3 marbles & ask him to
repeat the above
 Now what does he feel?
 Answer should be no friction or
heat
 Monolec acts like chemical ball

separate the rubbing surfaces of

 Demo oil/water samples
 First:
Commercial oil/water sample;
Show emulsification, discuss R&O
problems, short oil life, poor lube
film strength, high equipment wear etc
 Second: LE oil/water sample;
show excellent separation, oil
“tackiness” on to paper clip, long
oil life, good lube film strength

Conclusions
Conclusions
Not only must an air compressor oil reduce friction &
prevent wear but it must also perform the following
important functions:
 Remove heat by cooling & efficient heat transfer
 Suspend dirt & wear debris until filter can remove it
 Seal to allow efficient compression without leakage
 Coat the internal surfaces of compressor
to prevent rust & corrosion
 Minimize deposit & varnish formation

Conclusions
Conclusions
LE Compressor Oils fulfil all these important
functions in air compressors…
AND
AND more….
Help your customers to dramatically increase
their profits by converting their
Air Compressors to LE lubricants
They WILL
WILL thank you for it!
