Fan Performance

Bruning & Federle proudly offers Fan Vibration Analysis to ensure fans are properly balanced, whether the fans are bought from us, or from another supplier.


We also offer two lines of material handling fans.  The "B&F" line and the "Carolina" line.  Both fans are fabricated from 1/4" plate steel with heavy construction units available.  The "B&F" line offers extra heavy shaft and split housing bearings.

We also offer a "B&F" line and "Carolina" line of flexible tip rotary airlocks.  The "B&F" valve uses a cyclodrive gear reducer and has a removable scroll section for major replacement.  The "Carolina" valve uses a C-face right-angle worm gear reducer.  Both units have plate steel housings, T.E.F.C. motors, and a chain drive with guards.

All Housings and Impellers are REVERSIBLE allowing clockwise or counterclockwise rotation and multi-angular discharge positioning.  Our open radial blade wheels are mounted on ground and polished shafts and supported with self-aligning ball bearings.  Free-rolling action and a full load-carrying capacity are maintained even with shaft deflection or misalignment.

About Us

About Us

The Bruning & Federle headquarters is located in the heart of North Carolina. Bruning & Federle was founded in 1963 by long-time friends and business associates, Mr. Dave Bruning and Mr. Bob Federle.  In 1994, Bruning & Federle acquired an age old competitor: Carolina Blower Corporation.  Being located in Statesville, NC put Bruning & Federle in close proximity to the furniture industry, where the market flourished until the late 1990's.  Due to the ever-changing demands of a global economy, diversification became a necessity and recent projects have expanded to include: foam recovery/recycling, environmental air purification, arresting of paper waste, automotive/metal finishing, grain conveyances, mining dust containment/extraction, metal tooling mist elimination, textiles dust extraction, pneumatic transfer and powdered pigment subjugation.  The above products have been located throughout the United States, Canada, Mexico, and Brazil.  Between Bruning & Federle Mfg. Company and its subsidiary of Carolina Blower, there is a combined manufacturing-design-installation experience of over 120 years.
