When installing a NVE 4307 blower we recommend a normal R.P.M. range from 2700 to 4000. Other speeds are o.k. as long as
exhaust gas temperatures read on the supplied thermometer do not exceed 290 degrees F over ambient temperature.

The maximum allowable operating
vacuum will vary depending on R.P.M.,
ambient temperature, altitude and
time running. The basic principle to
keep in mind is - faster R.P.M., higher
air temperature and longer run time all
equal more heat in the pump. When
installing an NVE 4310 blower we
recommend a normal R.P.M. of 4000.
Other speeds are o.k. as long as exhaust
gas temperatures read on the supplied
thermometer do not exceed 375
degrees F.
