Wing Fan S1HR Fan Blade, 45° (Multiwing 1HR Equivalent), Uncut

Wing Fan S1HR fan blade in PAG (glass-filled nylon), sold uncut at full molded length. Right-hand blade. 45° pitch, molded into the blade. Fits H-series hubs (3, 6, 8, 10, 12 and 14 blade). H blades need an H hub; they do not fit Z or W hubs. Equivalent to the Multiwing 1HR 45°. Used on Cummins and Smithway trailer cooling fans, among others.

Uncut or cut to your diameter

New blades are molded longer than the ones on your fan. Most fans are cut to diameter at the factory, so the printed number on the blade (S1HR) tells you the profile, not the length. Choose Cut to my fan diameter above, enter your finished diameter and hub size, and we cut the blades before they ship. The cutting service is added to your cart automatically, with 20% off when you buy 6 or more blades. Or choose Uncut and trim them yourself.

For a complete fan that will run at high speed we also offer balancing. Send in your hub, or buy a complete fan, and ask us about it.

Left-hand or right-hand?

The R in S1HR means a right-hand blade. Stand with the air blowing in your face and look at a blade tip, toward the center of the fan. On a right-hand blade the leading edge (the thick, rounded edge) is on your right; on a left-hand blade it is on your left. See the diagram in the photos above. The left-hand version is the S1HL.

Not sure what you have?

Use our fan identification form. It walks you through the diameter, blade count, hub size and series in a few minutes, and you can attach photos. We will confirm the right blade before you order.
