It’s built for durable and dependable functioning, no matter how demanding the conditions may get. With all the parts and packages designed and manufactured in our state-of-the-art facility in Michigan, you can be sure of the best service and support for your operations.

* 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 blower. When installing a NVE B250 blower we recommend a normal R.P.M. of 2200. Other speeds are ok as long as exhaust gas temperatures read on the supplied thermometer do not exceed 380 degrees F.
