MBM Jets BK (Brady, Kress) 90 P
  We offer this fan in two main variants reinforced plastic composite (orange rotor), or carbon composite. Fans are Dynamicly ballanced .
This fan is hand built in the United States of America. It is a marriage of the technology of developed by Robert Kress former Grumman aeronautical engineer who's work includes the original F-14 Tom Cat. and Morris Brady Propulsion Technical adviser and Board director of VNI.PHS, companies that dealt in research subs and hovercraft concepts. You may well remember the Kress Jet fans that started the electric ducted movement here in the us by Robert Kress some 12 years or so ago our fan was is the first Electric ducted fans commercially available. Sadly Robert is no longer with us, but Morris has gone on to improve upon the designs that Bob has left with him.
Made with precision, for the utmost structural integrity, and efficiency.
8+ lbs of thrust can be achieved with this fan.
etages is the total efficiency of ducted fan+motor+speed control+cables under static conditions.
