Pneumatic Tool Lubrication Specifications
As with any pneumatic tool, proper lubrication of Standard Pneumatic and
Electric Tool Company tool(s) will increase operating reliability and
tool life. The high quality materials and precision engineering of our
tools permit the tools to take a great deal of abuse and operate with
faulty lubrication without apparent failure. Proper lubrication should
not, however, be ignored, as it will increase the long life character,
which is already built into each tool. Our examination of tools returned
for repair shows that about 2 out of 3 have not been lubricated properly.
The ideal air supply to our tools can be achieved with our Model 280 Filter-Regulator-Lubricator.
The filter element removes contaminating solids, oils and liquids which
may be in the compressed air line whether newly installed or not. This
filter unit is equipped with a petcock for "dumping" the contaminants
without shutting off the air supply.
The regulator controls the air supply to maintain a constant pressure
at the tool even though there are changes in the flow demand and or inlet
Proper adjustment of the lubricator is the key to proper tool lubrication.
With the tool running, set the lubricator to deliver one drop every minute.
Only a small percentage of this drop goes downstream in a mist form to
lubricate the tool. The remaining percentage of the drop adheres to the
air hose wall.
When other manufacturers of lubricators are used, it is recommended that
the customer check with that particular manufacturer for the proper procedure
for setting the lubricator to deliver 1/10 of a drop per minute to the
tool. Many lubricators especially larger units require high airflow rates
for the lubricator to operate properly. Therefore, the manufacturer should
also be asked to verify the operation of the lubricator at a 3.6 cfm flow
rate for the 2000 series and a 10 cfm flow rate for the 8000 series.
Multiple tools on one air system present another problem. When several
tools are connected to the same lubricator, it is impossible that the
correct amount of lubrication is going to each tool. Since it is highly
unlikely that the same number of tools would always be operating at the
same time, the airflow through the lubricator would be a variable; thus
the amount of lubrication put into the airflow would also vary. However,
with the micro fog type of lubricator such as our Model 280, the oil particle
size is such that the oil stays suspended in the air through several take-offs
better than with other types of lubricators without wetting out, which
results in multiple tools on the same line being better lubricated.
The position of the various tools in the system in relation to the distance
away from the lubricator would also cause a variance in the amount of
lubrication to each tool. If several tools must be connected to the same
lubricator, the same procedure for setting the amount of lubrication on
one unit should be used with only one of the tools running. It is assumed
that the increased airflow of several tools operating at the same time
will pull more oil into the system. The maximum number of tools that we
recommend connected to one Model 280 is two.
The best method of connecting multiple tools on one system is to have
each tool connected directly to its own lubricator (Model 282) with several
lubricators being connected to the same filter-regulator (Model 281).
Here again, the maximum number of tools that can be connected to the same
Model 280 is two. If more than is required on the same system, a larger
filter-regulator unit is recommended such as our Model 285. If the customer
uses a competitive version of our FLR's then they should check with that
manufacturer to be sure the unit will provide enough air flow to supply
the tools, even if they were all operating at the same time. The air consumption
of the 2000 series is 3.6 cfm. while our 8000 series consumes 10 cfm of
The oil recommended for use with Standard Pneumatic & Electric Tool Company
tool(s) is part number 100. It is a special formulation that is not affected
by any water, which may have condensed in the airlines. It can mix with
water without forming any detrimental emulsions. When multiple tools are
used with a single lubricator, it is advisable to use a lighter grade
oil such as a S.A.E. number 10 non-detergent. This recommendation is made
without any inference as to any other lubrication product being inadequate.
But in the opinion of the engineering department it is the preferred lubricant.
