INSTALLATION AND OPERATION MANUAL
Introduction
A LubrimistKOil Mist System is a centralized lubrication system that generates, conveys,
and automatically delivers lubricant to bearings, gear boxes, chains, and sliding surfaces
in various industrial machinery and equipment. This publication provides instruction and
information for the LubrimistKModel “PRY330” Oil Mist Generator. Design,
application and distribution of LubrimistKOil Mist is covered in other publications. Call
the Lubrication Systems Company office nearest you for additional information.
Description
The LubrimistKModel “PRY330” Oil Mist Generator is designed for use in small to
intermediate size oil mist preservation systems. The “PRY330” generator is equipped
with the necessary monitoring features. As with all Lubrimist K Oil Mist Generators, the
generator utilizes the proprietary Vortex mist generation technology which delivers
superior reliability and performance. Model “PRY330” is equipped with one 300 bearing
inch and one 1000 bearing inch oil mist generating head providing an oil mist supply
range of 3.0 to 30.0 SCFM.
The heavy gauge stainless steel oil mist reservoir has a seventeen gallon operating
capacity and includes an oil level sight glass, pressure relief valve, mist pressure gauge
and oil filter as standard equipment.

Installation
Location / Mounting
Choose a central convenient location, allowing enough room for air, oil and drain
connections. Ensure easy access to the front of the unit. Install the “PRY330” unit in an
upright position and secure with four anchor bolts that are suitable for the type of
foundation used ( i.e. wood, concrete, steel etc.) Anchor bolts are not provided with the
unit.
Mist Distribution System Connection
Connect the oil mist distribution system to the oil mist outlet (2” NPT) located on the top
right corner of the unit. Do not use Teflon tape or conventional pipe dope. A non-
hardening thread lubricant such as Lubrimist
K Part No. 77-600-947 should be used on the
pipe thread.
Compressed Air Supply
Connect a clean, dry compressed air supply to the inlet air supply (1/2” NPT) located on
the left side of the unit. The inlet air supply should be capable of delivering the
maximum SCFM rating for the particular mist head being used. Mist flow rates for the
oil mist generating heads are indicated below. Recommended air service is 32 SCFM at
55 PSIG. This is the minimum required air supply necessary to ensure that the unit is
operable over the entire mist generating range.
Mist Head Size
(Bearing Inches) Mist Flow Range ( SCFM )
300 BI 3.0 - 9.0
1000 BI 9.0-30.0
Note: Maximum air supply pressure is 125 PSI
Oil Supply With a Spin-On Oil Filter
An oil fill connection (3/4” NPT) is located on the right side of the unit. This port is
available for connection to a separate pressurized bulk oil supply. Level is controlled and
maintained by a user furnished block valve. A bulk oil supply system can be supplied as
a separate item. If a bulk oil system is not used, a manual oil fill port is provided on top
of the reservoir. When using the manual fill port, care must be taken to ensure that only
clean oil is added to the reservoir.

Start-Up
Prior to start-up recheck all connections and ensure that all fittings are tight. Ensure that
the oil mist distribution system, reclassifiers and application point connections, vents, and
drains are properly installed.
To Start the Lubrimist K Model “PRY330”:
1. Fill the reservoir with clean oil. If a bulk oil
fill system is used, turn on the pressurized oil
supply feeding the model “PRY330”. If you are
using a LubrimistKModel “BST” bulk oil
supply tank see the operating instructions for
correct start-up procedures.
Open the user supplied oil block valve in the oil
supply line connected to the oil inlet. Oil
pressure will cause the reservoir to fill with oil.
Do not exceed the “HIGH” oil level mark on the
oil level sight gauge (1).
2. Turn on the air supply at its source. Adjust
the air pressure regulator (2) by turning the air
filter/regulator knob until the correct mist
pressure is achieved on the mist pressure gauge (3).
Note: If the regulated air pressure must be set above 55PSI in order to maintain 20in H2O
mist pressure, it will be necessary to switch to the larger secondary oil mist head (this
procedure only applies if the “PRY330” unit is ordered with two mist heads). To switch
to the second mist head turn the 3-way ball handle (4) toward the mist head to be used.
When the desired mist head has been selected it may be necessary to readjust the
regulated air pressure (2) by turning the air filter/regulator knob until the correct mist
pressure is achieved on the mist pressure gauge (3).
THE REGULATED AIR PRESSURE MUST NOT BE BELOW 10 PSI. IF
UNDER 10 PSI, THE VORTEX MIST HEAD MAY NOT PRODUCE MIST. IF
THIS CONDITION EXISTS, A LOWER CAPACITY MIST HEAD SHOULD BE
INSTALLED OR ADDITIONAL LUBE POINTS SHOULD BE ADDED TO THE
SYSTEM.)

Operation
The daily operation of the “PRY330” oil mist system consists of checking the oil mist
generator and the lubricated equipment. As machinery is added and removed from the
equipment preservation yard, the air pressure regulator will need to be adjusted to
maintain the proper mist pressure. Oil consumption will also vary with the quantity of
equipment items. Except for emergencies, routine adjustment of the generator is not
required while the equipment population is stable. The “PRY330” oil mist preservation
system, once installed and balanced, supplies a constant amount of oil mist to a number
of lubrication points.
Variations in the oil mist pressure or regulated air pressure (supply pressure) from the
initial set points is an indication that some component of the mist system or compressed
air supply system may have malfunctioned. Adjustments of the controls to offset the
failure symptom may lead to more serious problems before correction of the root cause
can be made. Please refer to the trouble shooting section of this manual for suggested
corrective actions.
The following checks should be made on a daily basis:
1. Check reservoir oil level, see start-up procedures on how to fill the oil reservoir.
2. Check the regulated air pressure and mist header pressure. Changes or fluctuations in
mist pressure readings indicate broken or plugged lines or reclassifier fittings in the
distribution system. These problems must be corrected before adjusting the regulated
air supply.
Maintenance
The following maintenance procedures should be performed on at least a semi-annual
basis to help ensure proper system operation. If your “PRY330” unit is installed in an
extremely dusty or humid environment or if you are concerned about the quality of your
compressed air supply, the maintenance schedule should be accelerated. Consult with the
nearest LSC office/service center for further discussion and recommendations.
3. Replace air filter element (P/N 77-500-472) and oil filter element (P/N 77-500-487).
4. Inspect and clean interior of the “PRY330” reservoir.
Use lint-free rags to wipe the reservoir.
5. Inspect and clean the oil suction screen.
Use cleaner that is compatible with the oil and use lint-free rags.
IMPORTANT: DO NOT DISASSEMBLE THE VORTEX MIST HEAD.

4. Make an overall assessment of the “PRY330” and mist distribution system and correct
obvious deficiencies and problems.
Trouble Shooting
6. Check the oil level by making a visual check of the oil level sight gauge. If the oil
level is below the “LOW” oil level mark, check the oil supply system to insure that oil
pressure is being maintained to the oil filter.
7. Check the mist pressure by making a visual check of the mist pressure gauge. A
typical high mist pressure is at 30” and a low mist pressure is at 10” H2O pressure
respectively. Normal operating pressure for “mist” reclassifier systems is 20” H2O.
Although a high mist pressure may be corrected by adjusting the regulated air supply, it
must be recognized that high mist pressures are most likely caused by a situation external
to the oil mist generator. The following should be investigated:
A) Low pressure may indicate a leak in the distribution system, a missing
reclassifier or a broken line.
B) High mist pressure may indicate plugged mist fittings, restricted bearing housing
vents or an open air by-pass valve in the mist generating head.
C) No mist pressure could indicate loss of air supply to the mist generator. Check
the inlet air supply.
D) Surging mist pressure usually is caused by an oil pocket or trap in the distribution
header or fluctuating air supply,

Controlling the Oil Mist
LubrimistKVortex oil mist generation technology allows for maximum control and
adjustment of oil mist properties. There are three
basic controls:
1. The INTEGRAL AIR FILTER-REGULATOR
is used to adjust the volume of air flow to the
Vortex chamber which in turn controls oil mist
volume. The volume of oil mist is proportioned
to each bearing or application point by the
reclassifier. With the air bypass valve
(described below) closed, the air pressure
regulator setting must be high enough for oil
mist production. Regulated air pressure should
be adjusted to maintain proper mist pressure.
Since changes in regulated air pressure affect
the volume of oil mist produced, it also affects
oil consumption.
2. The OIL FLOW VALVE controls oil mist
density (oil/air ratio). Its normal position is
fully closed. By turning it counter clockwise
toward “Less” (opening the bypass) the mist
density can be reduced when leaner density oil
mist is desired. It should not be opened more
than three turns. Adjustments to the oil flow
valve do not affect oil mist pressure. (See Fig.
No. 8 for location)
Note: The oil/air ratio or mist density is also
dependent on the characteristics of the oil, oil
temperature and supply air temperature.
Density decreases with lower temperatures and
higher oil viscosity.

3. The AIR BY-PASS VALVE controls mist pressure without effecting oil output. Its
normal position is fully closed, but by turning it counter clockwise toward “Open”
more air will be added to the oil mist leaving the generator thus increasing mist
pressure and reducing the oil/air ratio. Velocity of mist through the distribution lines
and reclassifiers will also increase when this valve is opened.
Note: The oil/air ratio, or mist density, is reduced by opening the air by-pass valve.
However, oil output is not affected.
