Established by Nigel Farrow in 2020, Farrow Flow makes patented airflow inserts that turn straight-line air into a controlled vortex for blasting, painting, and powder-coating equipment. Designed and manufactured in Pennsylvania by Pennsylvania companies, its drop-in devices are intended to upgrade existing systems rather than replace them, with the original insert developed from work on the Farrow System slurry abrasive machine. Farrow Flow is based in Downingtown, Pennsylvania, and sells through distributors in the United States and abroad.
