  Designed and engineered to
produce suction from 2 to 10 ins [50 mm to 250 mm] mercury for air pressure
from 1 to 8 psi [0.07-0.56 kg/cm2].
Doctaire Sturtevant Turbo
exhausters and blowers are constructed for continuous duty, every day, year
after year with out adjustments or replacement, minimizing the need for
maintenance. |
ADVANTAGES
- Straightforward design, with
no fine internal clearance or wearing parts requiring lubrication.
- Air delivered is free from
oil vapor, moisture or other contamination. Air is also completely uniform and
free from pulsation.
- Power consumption varies with
the volume of air delivered.
- No need for relied valves or
other safety devices because Doctaire-Sturtevant incorporate self-unloading.

APPLICATIONS
These are some of the many applications of Doctaire-Sturtevant
Turbo-Exhausters & Blowers. We will also gladly put our experience to work for
you on any application requiring air under suction or pressure and welcome all
new problems.

CONSTRUCTION
An exhauster or blower consists of a rotating system of shaft and impellers
operating in specially designed inlet, outlet and intermediate sections, the
whole assembly being mounted either on a combined in line or box frame mild
steel fabrication assembly set down on felt under base or anti vibration
mountings.
SHAFT & IMPELLERS
The shaft is of a high-grade carbon steel, machined and ground to accommodate
the impellers & bearings. The impellers are a composite construction of
castings in high-tensile Aluminium with steel shrouds riveted on, all
accurately balanced and held securely on the shaft by heavy, endwise locknuts.
INLET, OUTLET & INTERMEDIATE SECTIONS
Castings are either in iron or aluminum to form the machines casing.
Precision-machined with spigot and socket faces, and after assembly, held
together by tie-bolts. The intermediate sections are provided with fixed with
fixed-guide vanes for the efficient conversation of air velocity into
pressure.
BEARINGS
Heavy duty ball and roller bearings, fitted in the easily accessible external
grease packed housings bolted to the inlet and outlet sections, are used in
all machines.
DRIVES
Doctaire-Sturtevant Turbo-Exhausters and Blowers are usually vee-rope driven
from electric motors. In the larger size the machines can be direct coupled to
electric motors. Guidance dimensions of standard units from 6X5 to 12X10 are
available with us for space allocation. Normally no holding don bolts are
required.
Additional units are available from 6X3 to 14X8. Size, number of stages and
speed are selected to suit the customer's exact requirements. Clients are
therefore invited to state their application.
