CAUTION! Dangerous (flammable or explosive) or aggressive (corrosive)
gases should not be handled by the standard blower.
Handling of flammable or aggressive gases and vapors may be possible by using
a specially configured or modified blower. Contact factory for additional
information. The standard blower is not suitable for operation in explosive
environments as defined by NFPA 70. Contact factory for assistance.
CAUTION! The ambient and suction temperatures should be between 40
and 105 F. For temperatures outside this region, please contact the
factory.
The maximum permissible pressure difference for vacuum or pressure is
dependant on the motor rating (See Tables 1 to 4 for detailed information by
model number.) and power supply frequency. The figures in Tables 1 to 4 are
computed assuming an ambient temperature of 77 F (25 C) and a local
barometric pressure of 1013 mbar (sea level). Operation at an ambient
temperature of 104 F (40C) is the maximum permissible, and will result in a
reduction of 10 percent on maximum vacuum or pressure attainable by the unit.
For temperatures between 77 F and 104 F, reduce the maximum pressure
reduction is a linear function of temperature.
