Vanes are a critical component for
peak vacuum pump performance. Vane materials must exhibit a
combination of characteristics to meet your performance
expectations:
 |
Low thermal expansion to avoid
excessive swelling that can cause a vane to seize in the rotor
slot or against the end plates. |
|
|
Low moisture absorption so,
again, they do not swell and seize the pump. |
|
|
High acid resistance for long
lasting performance and no degrading or delaminating in
corrosive service pumps. |
|
|
Flexural
strength to prevent the vane from bending under load, creating
extra friction and seizing the pump. |
GasFlo Products offers two types
of vanes for the best combination of price and performance.
PREVAIL vanes provide excellent performance in standard pump
applications. PREVAIL is an epoxy filled fiber glass laminate with
continuous woven carbon fibers for exceptional strength and built-in
lubricity. PREVAIL vanes are supplied in kits for the following
series of pump
| |
Alcatel |
SD, I, A, AC & C1
|

Leybold |
B & A |
| |
Edwards |
RV & E2M |
Additionally, PREVAIL vanes are
supplied for the first stages of corrosive series pumps (see below).
PREVAILplus vanes offer high performance where it
is required in semiconductor processes or other applications that
generate reactive aqueous acids. PREVAILplus is
a solid, long-fiber carbon composite with exceptional flexural
modulus and high resistance to thermal expansion, acid attack and
moisture absorption. PREVAILplus vanes are
available for individual sale and are supplied for the second stage
in kits for the following pumps:
