Dust Collectors
Bag and cartridge filters for furnace fume and plant dust
Overview
What it is and where it works
Filter systems that capture fume and dust from melting furnaces, sidewells, dross handling and scrap preparation. On melting lines, hot gas is usually cooled before the bags and dosed with lime to neutralise acid components and protect the filter from corrosion. Baghouses remain common in foundries, with cartridge collectors increasingly used for furnace fume.
- Gas cooling
- Furnace gas up to about 350 °C cooled to about 120 °C before the filter (documented case)
- Lime dosing
- Lime injection neutralises acid gases and limits corrosion

Frequently Asked Questions
Why do I need lime injection?
Fume from melting with fluxes carries acid components; lime neutralises them and protects bags and steelwork from corrosion. Some permits set a minimum lime rate.
Can the bags take gas straight from the furnace?
Usually not; furnace gas is cooled first so it stays within the bag material's temperature limit. Send us the gas temperature at the inlet.
