jet fan definition
jet fan means a fan that produces a high velocity jet of air in a space (thrust), unconnected to any ducting, where the jet of air entrains movement of the surrounding air, creating an overall air flow through the space. It is designed for operation with open inlets and outlets rather than operating against pressure and is capable of achieving at least an efficiency of 35%, assessed in accordance with Annex IV, point 3;
jet fan means a fan used for producing a high velocity flow of air in a space. Typical function is to add momentum to the air within a tunnel. Inlets and outlets are not ducted.
jet fan means a fan designed and marketed specifically to produce a high- velocity air jet in a space to increase its air momentum. Jet fans are rated using thrust. Inlets and outlets are not ducted but may include acoustic silencers.
More Definitions of jet fan
jet fan means an axial, centrifugal or radial fan that produces a high velocity jet of air in a space (thrust), unconnected to any ducting, where the jet of air induces movement of the surrounding air, creating an overall air flow through the space, and that is designed for operation with open inlets and outlets rather than operating against pressure, including radial and centrifugal jet fans with an angle entrance of ≤ 90° to the outlet;
