SQI Industrial Fan Applications
The SQI wheel with radial blades is designed to handle various types of materials, long fibers or other stringy material as well as sticky, heavy or abrasive dust airstreams. Typical applications include conveying, induced draft, industrial ovens, and similar high temperature installations to 650°F. For greater safety in explosive environments, spark resistant construction is offered. Lint-free construction, in which housing hardware is reversed to limit obstructions in the airstream, minimizes lint build-up. The versatile SQI Industrial Fan is furnished in eight sizes in Arrangements 1, 9, 9H.
