The big, slow backward-curved wheel - high static from a constrained footprint, at a tip speed that keeps it quiet. Every card is a real dispatched build, with its verified duty point.

Flow on this page runs from 550 to 6,000 CMH, against static pressure to 1,700 mmWC, at gas temperatures to 200 °C. The wheels here are large backward-curved. How we choose for this duty: one inlet or two.



















Duty points are the customer's design conditions, verified from our manufacturing records (GA drawings / M.O. sheets). Customer names and identifying marks are withheld.
Give us the flow, static pressure, gas and temperature — our engineers size it and quote in 3 to 5 working days.*
