Many fan types are available to meet process needs. Here is a brief glossary.

General Ventilation Equipment.Ventilation equipment helps move uncontained air more effectively. Equipment in this category includes dilution ventilation (intake, exhaust, filtered and recirculation), makeup air, and personnel or equipment cooling.

Process Ventilation Equipment.Process ventilation fans and blowers help control or contain the movement of air contaminated by fumes, dust, corrosives, temperatures or materials from one point to another. Equipment in this category includes axial flow fans and centrifugal fans.

Fiberglass Equipment.Fiberglass, corrosion-resistant fans and blowers for general and process ventilation applications are recommended where corrosive elements exist in fume or vapor form.
