    Got into a swamp cooler (evaporative cooler) conversation today. Cust says no volume of air like it should have. Claims it needs a larger motor. I say I have fixed this before, and it is not the motor's problem. All motors are the same RPM I explain, and it is a problem with ratios of drive / fan pully. He in not so many words says he does not think that is it, but I have put a larger pully on the drive and smaller on the fan with great results...TONS of air. Besides saying it is like a 10-speed bike, how does one explain this?

    motor

    Its all in the ratio. If you have a 10" pully on the drive side (motor) and a 1" pully on the driven side (fan) every time the drive pully makes one revolution the driven pully will make 10.
