Aeration Disc
Shick Esteve’s Aeration Disc is designed to enhance the discharging of aeratable products from bulk storage bins and silos by forcing air through a fabric-base layer and fluidizing product to discharge. The innovative dished-head design requires minimum head height for easy accessibility to equipment in the silo skirt. The large square footage of aeration material provides for enhanced clean out of stored products. The air disc is operated in conjunction with a PD blower and control valves.
