Greenheck inline fan models meet a wide range of indoor applications for commercial and industrial facilities, including commercial exhaust fans, air supply, and air recirculation solutions. Models are available in direct or belt-driven configurations for clean air and sound sensitive applications. Direct d rive configurations include our CSP-A, CSP-B and SQ models, while our BSQ is a belt-driven configuration. Our inline fans are constructed with a galvanized steel housing and either a backward-inclined or forward -curved centrifugal wheel depending upon the model.
