"Bifurcated fan" What does the term "Bifurcated fan" actually mean? Please provide a link to some examples and or illustrations which clarify the term. The images and text I've seen using Google image search "Bifurcated fan" have shown................................. 1. Axial fan with centered engine pod; front intake, rear thrust. 2. Axial fan with centered engine pod; front intake, right and or left thrust (sides). 3. Axial fan front and back (possible common shaft) opposing intakes, with exhaust/thrust top and bottom or right and left (sides). 4. Axial fan with remote drive (via belt) including combinations above (1,2, & 3). Like many architectural terms (my thing) you may not obtain it's true meaning and context from regular dictionaries. I will assume "Bi" means split in two somehow. That could mean split thrust, split intake or split flow by engine placement. What the heck is "Furcated" by it's self?
