The DuroFlow's 40 pound square load design allows models
with longer lobe lengths to operate at higher pressures and deeper
vacuums. Additional design features include oversized bearings, ductile
iron rotors and one piece high strength shafts.

Solid rotors on the 3000 and 4500 Series eliminate
vibration caused when hollow rotors become unbalanced due material
build-up inside the rotor cavities.
|
DuroFlow blowers are flexible enough to accommodate
application air direction, with vertical or horizontal flexible mounting
capabilities. DuroFlow blowers are also center-timed, which allows you
to operate them in either rotation. This flexibility reduces inventory
requirements and allows you the flexibility for mounting into any
system.
|
Either surge conditions or high torque start-ups can cause
some blowers to lose their timing, but the DuroFlow blower has its
timing gears mounted on machine shaft splines. This means your blower
will spend more time in operation and less time off-line being repaired.
|
Quieter operation with helical timing gears.
|
Oversized double row ball bearings support each shaft and
fix the rotor position. This prevents destructive axial rotor movement
commonly caused by misaligned V-belt drives.

| You won't have to worry about messy oil leaks since
DuroFlow uses Viton® oil seals for maximum seal life and leak-free
operation, even in continuous, severe-duty applications. Viton® oil
seals allow the blower to operate with a discharge air temperature up to
350° F. DuroFlow blowers also offer a vented seal arrangement
where the seal cavity can be piped back to the inlet of the blower to
capture any gas that may leak past the seals. |
Another maintenance time saver is DuroFlow's splash
lubrication system. Splash oil lubrication at both the gear and the
drive ends provides superior gear and bearing lubrication at all
operating conditions with minimal maintenance. The 3000 and 4500
Series blowers have interconnected oil sumps that facilitate easy
filling and draining. The 7000 Series features individual over-sized
sumps for extended operation between oil changes.
