| Propellers are carefully selected to fully utilize the available power. Maximum air flow is balanced against the motor's horsepower limit. |

|
Air flow patterns are measured on axis as well as off axis. Air straighteners can be used to modify the units' flow pattern. |

|
Noise generated by our units can be determined in terms of octave band, third octave band and overall levels for sound power or sound pressure at a given distance. |
