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.

Maximum 4500 RPM Intermittent Operation Only.
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.
