1600 Heavy Duty Vacuum Blower

Made in the USA

The certified beast of the vacuum blower range – the Challenger Series 1600 CFM tri-lobe vacuum blower tackles the toughest industry jobs with ease and efficiency. This system is built to function continuously in maximum vacuum (typically 27’’ HG) and is ideal for septic pumping, environmental waste removal and more. With its improved vacuum efficiency and reduced mechanical noise, this system will give your standard pump truck the power it needs to outperform.

* 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 1600 blower we recommend a normal R.P.M. of 3600. Other speeds are ok as long as exhaust gas temperatures read on the supplied thermometer do not exceed 380 degrees F.
