For ambient temperatures less than 10° F, but not less than - 20° F, the use of oil sump heaters,
heated enclosures or synthetic lubricant is required.

For ambient temperatures 10° F to 32° F, the use of oil sump heaters, heated enclosures or

The lubricant viscosity must be 70 SUS minimum at the lubricant operating temperature.
The pour point of the lubricant should be at least 5° to 10° F below the minimum expected ambient
temperature.
For continuous operation, where the lubricant temperature exceeds 200° F, synthetic lubricant is
recommended.

when the machine is not operating. Run the blower for one hour. Shut off the blower and drain the lubricant
completely. Refill the blower with the new lubricant.
MAINTENANCE
AIR FILTERS AND FILTER -
-
- SILENCERS
Servicing the air filters is one of the most important maintenace operations to be performed to insure
long blower life.
Servicing frequency of filter elements is not time predictable. A differential pressure indicator, with a continuous
gauge reading, should be installed across the inlet filter. It will tell how much of the service life of the filter element
has been used. It will also eliminate
both premature filter servicing and premature blower failure due to a plugged filter when the filter pressure drop is
used to establish maintenance points.
In all cases refer to the filter manufacturer
’s service instructions. Due to the many types of filters, it is not
practical to give specific instructions covering all models; however, the following paragraphs describe some of
those most commonly used.
NOTICE
No matter what type of filter is used, always make sure all seals, gaskets, clamps and hose
connections on the filter and inlet line are absolutely air tight. Each time the filter is serviced,
inspect interior of the blower for dirt.
