The vacuum blower, featuring tri-lobe rotors, is designed
for maximum positive displacement and manufactured
using special porting technology to significantly reduce
noise.
lubrication for both the gear end and drive end of the
blower is provided by full oil splash. unlike grease
lubrication, oil-splash lubrication provides for longer bearing and seal life through improved
heat dissipation.
At the gear end, the timing gear teeth are lubricated by submersion in oil with the gear teeth
serving as oil slingers. At the drive end, the bearings are also lubricated by submersion in
oil with oil slingers attached on the shafts.
The performance and life of the vacuum blower is greatly dependent on the care and
proper maintenance it receives.
Because of the close tolerances between the 3 lobes and housing of the vacuum blower,
solid objects entering the inlet will damage the internal lobes, gears, bearings or drive
system.
To prevent this from happening, a stainless steel filter screen has been placed at the
vacuum blower intake inside the vacuum recovery tank. This stainless steel filter system
should be removed for cleaning on a daily basis.
use caution when the CDS is being run for test purposes and the vacuum inlet is open.
unregulated vacuum may cause injury if body parts come in contact with the open vacuum
inlet.
