Dust Collector Upgrade for GrainCorp

Location: Dunolly, Australia

Time: Feb 2025 - Present

FTPL#11489

Background 

GrainCorp’s bulk grain facility in Dunolly needs to replace its aging dust collector to manage grain dust and allow for future extraction points. Fowlerex is asked to design and supply a new system and, after a site inspection, recommends increasing the airflow capacity from the specified 20550 m³/h to about 25000 m³/h to provide extra ventilation. The proposal calls for a PA120 × 4000 baghouse to be delivered to Dunolly, complete with drawings, fabrication, pulsing equipment, exhaust fan, ladders and platforms. The design incorporates a fully welded mild steel housing, anti-static filter bags and on-demand pulse cleaning to ensure reliable operation and compliance with explosion venting standards.
