ABOUT WENBOX SOLUTIONS
Wenbox Solutions is an Australian-owned small business based in rural Queensland.
Graham and Wendy are cattle producers on the Darling Downs, and first saw the CenterFlow container on a farm while visiting the United States. It was then they realised the potential for this product in Australia and how much safer it would make many tasks performed on farms, especially tasks that currently employ the use of a one tonne bag.
The CenterFlow’s usefulness goes beyond the agricultural sector and into industrial and food handling areas where it is necessary to store and move large amounts of product that is flowable.
Wenbox Solutions is the only Australian distributor of the CenterFlow container, made in America by Buckhorn.


CENTERFLOW CONTAINER
The reusable CenterFlow Container is the most efficient, versatile container available to transport and dispense seed, granular and pelletized materials, and small manufacturing components.
The CenterFlow Container features a smooth, sloped interior and a generous center exit port, which allows safe, complete emptying of contents in as quickly as 30 seconds. Its high-strength plastic construction handles loads up to 1,134 kg. The containers stack and nest to eliminate wasted space; their modular dimensions maximize trailer cubing to reduce freight cost.
Thousands of units are now in use for bulk product distribution, where the unique design provides a safer work environment, saves hundreds of work hours in handling flexible bulk bags and reduces packaging and disposal costs.
CenterFlow containers are available in Australia from Wenbox Solutions as a safer, more efficient way to move and store flowable products.
