Foundries & Smelters

Foundries and ore smelters require dust and fume collection for several different processes, such as sand casting and electric arc furnaces (EAF’s). High temperature dust collection and ventilation systems are often required to handle high dust loads of various particle sizes that are potentially hazardous or combustible.

The experienced engineers, programmers, project managers, and construction trade craftsmen at IAC understand the unique air handling requirements of foundries and smelters, and are here to help your operation meet or exceed nameplate production rates while adhering to applicable worker safety and environmental air quality control standards.

There are four main types of dust collectors used in foundries:



Baghouses work by forcing dusty air through a series of fabric filters, called bags. The filters catch the dust, which is later cleaned out and replaced. Baghouses are good at capturing small particles, and can be used for both sand and metal dust.


Cyclones use centrifugal force to separate dust from air. Dust is caught in a chamber at the top of the cyclone, while the clean air exits the bottom. Cyclones are good at capturing large particles, and can be used for both sand and metal dust.

Electrostatic Precipitator

Electrostatic precipitators use an electric field to attract dust particles to metal plates. The particles are then cleaned off the plates and recycled. Electrostatic precipitators are good at capturing both small and large particles, and can be used for both sand and metal dust.


Scrubbers use a liquid to capture dust from air. The liquid is then cleaned and recirculated. Scrubbers are good at capturing both small and large particles, and can be used for both sand and metal dust.

NOTE: IAC designs and builds dry scrubbers for gas stream conditioning, but not wet scrubbers.


The baghouse yesterday had one month of continuous operation. Personally, and in name of our team and Cerro Matoso, I want to say thanks to IAC, your experience, quality standards and all the effort of your team that was performed in our bag house project execution, thanks a lot."
