Table 4-3 – Maximum Operating Limits
WARNING
!
The maximum pressure differential is based
on the difference between the inlet pressure
and the outlet pressure. The maximum
pressure differential shall not be exceeded.
Exceeding the maximum pressure differential
will cause serious damage to the equipment
and could cause bodily injury.
WARNING
!
The maximum allowable working pressure
(MAWP) is based on the absolute pressure of
the blower housing and is NOT the maximum
allowable pressure differential. Exceeding
the MAWP will cause serious damage to the
equipment and could cause bodily injury.
To permit continued satisfactory performance, a
blower must be operated within certain approved
limiting conditions. The manufacturer’s warranty is,
of course, also contingent on such operation.
Maximum limits for pressure, temperature, and
speed are specifi ed in Table 4-3 on page 9
for various blower sizes when operated under the
standard atmospheric conditions. Do not exceed
any of these limits.
Specially ordered blowers with nonstandard
construction, or with rotor end clearances
greater than shown in Assembly Clearances
on page 39, will not have the operating
limits specifi ed here. Contact your
Tuthill Vacuum & Blower Systems sales
representative for specifi c information.
Special attention must be paid when a blower
has a higher than standard ambient suction
temperature. Special recommendations
for operating parameters and/or additional
cooling may be recommended. Consult the
factory or local representative for appropriate
information.
