Airtrol designs include a broad spectrum of applications including dry chemicals/catalysts handling, reaction, purging, transfer/storage, and loading/packaging. Many of these products have varying particle sizes, even down to sub-micron, and can be handled at elevated temperatures. Airtrol can supply ferrous or non-ferrous filters which can be rated for high temperatures, explosive applications, as well as high pressures (ASME). Also, special welding, grinding, polishing, and paint finishes are typically provided.
