Gas Diffuser Foundry are rugged, robust industrial grade devices used in foundries to absorb gases and a variety of other contaminants. This tool is very useful for degassing operations to eliminate hydrogen-induced porosity which results in high casting quality. It can also remove other impurities from molten aluminum melts. The Gas Diffuser Foundry we use is manufactured using high-quality fiber-reinforced plastic so it can withstand harsh working conditions.
