Lubricator Overview

ALE-14-B

1.1 GENERAL OVERVIEW

Norgren manufactures two main types of lubricators:
Oil-Fog and Micro-Fog. These units are mounted
directly into the pipe and add small amounts of oil
to the air flowing through them.

Oil Fog-Lubricators:

All the oil droplets seen in the sight dome are added
directly into the air flow. This results in relatively
large oil droplets passing downstream, suitable for
heavy lubrication applications eg single cylinders
and tools. Most competitive in line lubricators are
of the Oil-Fog type.

Micro-Fog Lubricators:

The oil droplets seen in the sight dome are atomized
and collected in the area above the oil in the bowl.
The smaller lighter particles are drawn into the air
flow and pass downstream.

As a result typically only 10% of the oil
seen as drops in the sight dome is passed
downstream. The remainder falls back into the oil
reservoir. Consequently, drip rate settings are
somewhat higher than their Oil-Fog equivalent. This
makes setting much easier, particularly in low flow
applications.

The fine Micro-Fog oil particles can travel
long distances through complex pipe work making
Micro-Fog lubricators suitable for multiple valve
and cylinder circuits.

1.2 WHAT ARE THE

DIFFERENCES BETWEEN

MICRO-FOG AND OIL-FOG?

1.2.1 Oil-Fog:

• Large oil particles not as fine as micro-fog.

• All oil drips seen in sight domes are

delivered downstream.

• For applications over short distances.

• Should be mounted at same level or higher

than device being lubricated.

• Standard bowls can be filled under

pressure. (Not on rapid cycle units).

• Suitable for heavy lubrication applications

eg single large cylinders and tools.

• Has a flow sensor which provides constant

oil output density for varying flows.

OIL-FOG LUBRICATOR

MICRO-FOG LUBRICATOR

1.2.2 Micro-Fog:

• Small oil particles; less than 2 micron.

• Only 10% of ‘drip rate’ is delivered

downstream as active lubricant (remainder
is returned to main oil reservoir).

• High drip rates make drip setting easier in
low flow applications.

• Can be mounted above or below the point
of application.

• Cannot be filled without shutting off
upstream air (unless a quick fill cap or
remote fill device is used).

• For use with lengthy air lines, multiple
valve and cylinder circuits.

• Has a flow sensor to provide an almost
constant oil output density for varying
flows.

1.2.3 Can Oil-Fog and Micro-Fog Units be

Converted?

Generally not, simply changing a green (Oil-Fog)
sight dome for a red (Micro-Fog) sight dome does
not change the function.

Some lubricators are designed around a

cartridge insert. In this case it may be possible to
swap the cartridge and sight domes to change the
function.

1.4 SETTING LUBRICATOR
DRIP RATES

1.4.1 What is the Correct Drip Rate Setting?

The drip rate will depend on the application, the
amount of lubrication required, the flow through the
lubricator and the lubricator type. In Micro-Fog
lubricators only 10% of the droplets in the sight
dome are carried downstream. The drip rate in
Micro-Fog lubricators therefore tends to be much
higher.

The following table can be used to estimate
drip rate for required flow. This is very much a rule
of thumb. In practice it is necessary to fine tune the
oil drip rate in each application.

Typical Drip Rate Typical Drip Rate Approx
per Minute per Minute Flow
Micro-Fog Oil-Fog scfm

(dm3/s)

20 2 10 (5)
40 4 20 (10)
60 6 30 (15)
80 8 40 (20)
100 10 50 (25)
120 12 60 (30)

1.3.2 Can the Drip Rate be Shut Off?

In lubricators with needle valve type sight dome,
yes.

Some Norgren sight domes use a felt pad
which is soaked in oil at the point where the drops
are formed. With this type of sight dome the oil
droplets cease once the felt pad dries out.

With the new style dome (L72/73/74 and
L07) complete shut off is not possible. Minimum
adjustment for the drip rate is around 1 drop per
minute.

1.5 FILLING METHODS

1.5.1 Oil-Fog and Micro-Fog Lubricators:

The standard Oil-Fog lubricators can be filled under
pressure ie without switching off the upstream air.
When a fill plug is removed a check valve in the
lubricator body isolates the inlet pressure from the
bowl and the reservoir will depressurize. The
lubricator can then be filled with oil. When the fill
plug is replaced, the reservoir will re-pressurize.

The standard Micro-Fog unit can only be
filled without isolating the upstream pressure if a
remote fill or quick fill nipple accessory is fitted. To
remove the fill plug of a Micro-Fog lubricator whilse
under pressure can be dangerous. If in doubt shut
off the upstream air!

1.5.2 Remote Fill Devices:

The remote oil fill system provides a means of filling
from a remote fill point, a single lubricator or a bank
of lubricators manifolded together. The remote fill
point may be connected to a portable reservoir or to
a centralized, permanent reservoir. A portable
reservoir permits the use of different lubricants in
different groups of lubricators to suit the
requirements of the machinery being lubricated. The
lubrication oil must be fed in at a higher pressure
than exists in the bowl.

The devices are NOT intended for
connection to an oil feed line which is under
constant pressure from a pump or pressurized
reservoir. The device cannot reset until the pressure
is removed. Such lines are a potential safety hazard
if they should leak or become broken.

1.5.3 Quick Fill Nipples:

The quick fill system is an alternative which allows
ease of filling a single Micro-Fog or Oil-Fog
lubricator without switching off the mains air (on
some units the quick fill nipple replaces the filler
plug).

To fill the lubricator, a quick fill connector
piped to a portable oil reservoir is snapped in place
over the quick fill nipple. The main oil reservoir can
now be pumped (or pressurized) to a pressure
greater than the lubricator bowl and the lubricator
filled.

1.3 LUBRICATOR SIZING

Lubricators are sized by downstream flow
requirements. An analysis of air flow use must be
made. After determining how much air flow is
needed, a lubricator can be chosen. Manufacturers’
curves will be like the one shown. For example, 50
scfm of 90 psig lubricated air is required. Enter the
curve on the horizontal axis at the required flow.
Read up to intersect the 90 psig line. Read the
pressure drop on left, vertical axis as approximately

2.3 psid. Pressure drop should be less than 5 psid.
If pressure drop is more than 5 psid, choose a larger
lubricator.

Always be sure that the lubricants in your system are
compatible with the materials in the lubricator you
choose. This is especially important for plastic
lubricator reservoirs. If in doubt, check with the
factory or use a metal reservoir.

1.6 OPTIONS AND
ACCESSORIES

1.6.1 Where can Liquid Level Switches be
Fitted?

Liquid level detection methods can be attached to
the 1 quart bowl and 2 & 5 gallon tanks.

1.6.2 Where can Remote Fill and Liquid Level
Switches be Fitted?

The smaller bowls, L73 and up, are all capable of
either remote fill or liquid level detection (but not
both at the same time!). The 2 quart and 2 & 5
gallon tanks only can have the liquid level switches
fitted.

1.6.3 How do Liquid Level Switches Work?

Liquid level switches are bipolar reed switches
which change state when the float rises and falls.

Liquid level switches are normally

connected to give an electrical signal when the float
falls (ie when the liquid level is too low). In critical
applications the logic could be reversed. Maximum
and minimum settings are possible too.

1.7 LARGE TANKS/RESERVOIRS

1.7.1 Which Units have Large Tanks/Reservoirs?

All units in basic 1/2” and above have optional
larger bowls/tanks.

Olympian Plus and Excelon 74 are limited
to 1 quart as standard. For 2 and 5 gallon capacity
use 15/17 Series, or the 10-028/-076 (2”)
lubricators.

1.8 APPLICATION SPECIFIC

UNITS

1.8.1 Do we Make Bearing Lubricators?

These are aerosol type lubricators. These
lubricators use air to get the oil to the point of
lubrication, however the tool or application is not
powered by the air. Although produced by Norgren,
systems for their application are designed and sold
by Engineering and General Lubrication Systems.

1.8.2 What is a Fixed Venturi (Bi-Directional)
Lubricator?

Standard Norgren lubricators use a flow sensor to
achieve constant oil density with varying flows. In
some applications high flow is more important than
constant density and a fixed venturi can be used
instead of a flow sensor. It may also be useful in
systems with rapid cycling. Consult Air Line for
more details.

1.9 OILS

1.9.1 What Oils are Recommended?

Recommended oils fall into 2 categories:­1 Oils recommended for use with all Norgren

units (valves, cylinders, fittings and FRL’s).

2 Oils which can be used with Norgren

lubricators but not necessarily with other
Norgren equipment.

Refer to ALE-29-2 for recommended lubricants.

1.9.2 Can Non-Recommended Oils be Used?

Some oils can be tested for suitability, but Norgren
cannot be responsible for use of non-recommended
lubricants.

Machine Bearing Lubricators

Machine bearing lubricators deliver a fog of small oil particles through a
manifold system to various machine elements (bearings, gears, chains, etc).
At the machine elements a nozzle-like fitting, called a reclassifier, causes the
small oil particles to combine into larger par ticles. The larger particles cover
the bearing surfaces with a protective film of clean oil.An air line filter and
pressure regulator must be installed immediately upstream of the lubricator.

How to Select

Selection requires a careful analysis of the lubrication requirements of the
machine. After the analysis, the proper lubricator, reservoir, and reclassifiers
may be ordered.The following is an abbreviated summary of the steps
required to analysis lubrication requirements of the machine. See Norgren
Publications NT-1, Design Manual for Machine Lubrication, for complete
details.

1. Determine the bearing inch requirement.
a. List and identify the bearing-inch rating of all machine
elements requiring lubrication.
b. List the reclassifier ratings required at each point of
lubrication.
c. Total the reclassifier ratings. This is the bearing-inch
requirement to use in selecting the lubricator.

2. Determine reservoir capacity required.
a. Calculate rate of oil usage based on bearing-inch rating.
b. Determine how often the reservoir can be refilled.
c. Select reser voir capacity.

3. Determine the air flow required. See the Operating
Ranges and Air Flow Requirements char t for air flow
requirements of the lubricator.

4. Determine any accessories required.
