In October 2021, Farrow Holdings Inc. launched a second company brand Farrow Flow, Inc. with a new patented insert that improves the performance of directional airflow in a conduit. This exciting invention improves the performance of all types of blasting by at least twenty-five percent.

In 1998, founder and inventor Nigel Farrow began looking for new ways to improve the speed and performance of an early generation slurry blast machine by adding heat to the process. The first patent named,“The Method for Removal of Surface Coatings” was granted and the first Farrow System was manufactured and in production. Farrow System is known as the industry standard on which all current day wet abrasive blast machines are built. During years of research and observation in the field, Farrow noticed the skilled blasting operators consistently moving the nozzle in a circular motion while blasting to get the best profile on the substrate.

The new challenge was then set to develop a way to mimic the rotation technique applied by the operator to spin the mixture at the end of the nozzle in order to increase momentum and lessen fatigue. The second patent name,“Insert for Use in Blasting” was filed and the first prototype developed. With the help of Prof. Hassan Shirvani, Director of Engineering Analysis Simulation at Anglia Ruskin University, discovered that the Farrow Flow replaces straight line air flow with a vortex inside of the pipe. This causes a tornado effect where the media exits the nozzle and is applied to the substrate producing more velocity and a wider spread. The other surprising effect witnessed is the rotation of the individual media particles themselves spin on the substrate acting like tiny brushes. This increased momentum created by the vortex creates a wider spread at the nozzle and is easily witnessed with the naked eye and a stopwatch.
