Industrial grade 
air circulators are designed for continuous use in industrial settings such as manufacturing facilities. They typically have totally enclosed motors which is important when used in a dusty or dirty environment. They typically have a higher air flow, more horse power and a longer warranty than their commercial counterparts. Available in a variety of mounting options such as pedestal mount air circulators, wall mount, ceiling mount, pole mount, I-Beam mount, suspension mount and even cart mount.

Commercial grade 
air circulators are designed for occasional use in clean and dry commercial applications such as schools, shops, offices or warehouses. Commercial grade air circulators cost less than their industrial counter part but generally do not deliver as much air flow, have less horsepower and have a shorter warranty. In general it is a lighter construction product.

Light duty & work station grade 
air circulators are designed for spot cooling individuals at work stations or in office settings. The air volume is generally not as high as the industrial and commercial models. Since they are lighter and more compact than the other grade fans they are perfect for moving around to those areas in need of gentle air flow.
