Multi Wing 100299/A

About 100299/A

Multi Wing 100299/A is a Multi Wing complete impeller number built with 9W-family (9WP) blades, about 56" (≈1,420 mm) in diameter with 10 blades. Add the identical impeller, its replacement blades or hub parts to your quote list; always state the suffix on the label (/A, /B).

Airfoil profiles have a wing-like cross-section and deliver high efficiency across a wide operating range. From 2H to 10G, this family covers the most widely used Multi-Wing profiles, from small motor cooling fans to giant cooling tower impellers.

The W series is designed for large-diameter impellers. The 5W, 6W, 7W, 9W2, 1W, 2W, 3W, 8W and TR11W profiles are mounted with W retaining plates and are used in cooling towers, large dry coolers, genset radiators and tunnel ventilation fans.

100299/A can be produced at diameters from 499 mm to 2,141 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
