OneSteel Reinforcing has consulted Donaldson Australasia to design and build a fume collection system based on its Downflow Oval Series (DFO). The company decided to upgrade its existing system in an effort to ensure containment of welding fumes on the process line. An upgrade was also required due to an increase in manufacturing at their Sydney plant. The Revesby plant produces galvanised wire mesh for residential, commercial and civil construction. The DFO are a line of patented dust collectors that use oval shaped cartridges, allowing large amounts of air to flow through the collector without damaging filters or increasing footprint size. The DFO collectors offer 25% more capacity than other dust collectors available when comparing standard industry performance.
