Creating Airflow Efficiencies

YORK® Centrifugal Inline Round (CIR) fans offer designers an excellent alternative to conventional blowers for boosting clean air in supply and exhaust systems. As an integral part of a ventilation system layout, CIR fans can be installed either horizontally, vertically or at any angle determined by the duct work. CIR fans from YORK® feature durable, galvanized steel construction in conjunction with a patented wheel design and deeply spun inlets to provide smoother flow through the ventilator.
