BEARING AIR
Using 1/4" O.D. x 1/16" wall tubing (clear see-through),
connect a properly ltered air source to the tting
marked “BRG” on the manifold. (See Figure 6.) It is
recommended to use clear (see through) tubing for
bearing air so that any contamination that gets past
the nal bearing air lter will be apparent.
Under the “Operation” section which follows, there is
a Caution regarding bearing damage if the turbine
is running while bearing air is OFF. Since the turbine
must not be operated without rst turning ON bearing
air, some means of assuring the presence of bearing
air before turning the turbine “On” must be provided.
One method is by interlocking the turbine drive air to
the bearing air (i.e. with an air piloted valve).
> Do not use tape or pipe dope on any air
ttings beyond the nal air lter for bearing
air. The tape or dope may break free and cause
plugging of the turbine air bearings, and result
in turbine failure.
> Provisions should also be made to assure
bearing air remains ON during the coast down
period when turbine air is turned OFF. (See
"Specications" on page 6.)
