As many of you know, I've been testing industrial/commercial ceiling fans at my shop, vintage and current. I've developed a routine where when on high, I go about 15' from the fan and gauge the airflow. Here are the results of my very unofficial testing:
Category 1: curved blade industrials with a strong breeze 15' from the fan
1986-current Gold Lines. 15' away the breeze is considerably stronger than directly under the fan, in some videos I compare it to having a box fan pointed at you at the 15' mark
1985 and earlier Gold Lines: Not quite as strong a breeze at the 15' mark, more breeze directly under the fan
Category 2: straight blade industrials with a strong breeze under the fan and strong gusts of wind 15' from the fan.
Cast Dayton/Leading Edge 56": Instead of a steady breeze like the curved blade industrials, you get periodic gusts of wind at the 15 mark, the cumulative air movement is similar
Hampton Bay 60": Very similar pattern to the 56" Leading Edges, possibly slightly less air movement
Crompton Greaves 56" (70s version): Noticeably less airflow than the Leading Edges.
Category 3: American made industrials with a strong breeze under the fan and a gentle breeze at 15'
Emerson StratoJet
Fasco Heat Cycler
Emerson "Heat Fan" (blenderfan): These three are almost identical in air movement and pattern.
Category 4: Industrials with a gentle breeze at 15' and a less than impressive breeze underneath the fan:
Airmaster (stamped)
60" Canarm
1997 Silver Line
56" cast Canarm: These are also almost identical in airflow. I expected more of the cast aluminum Canarm, perhaps testing it on the factory (too long) downrod skewed the results.
Category 5: Straight blade industrials with a strong breeze under the fan and almost no discernible air movement at 15'
Dayton Lasko
Nutone Proline II: In both cases, at 15, you could tell air was moving but you couldnt feel a breeze
BONUS CATEGORY: Exceptional 60" Industrial fans:
60" Leading Edge (cast): Like the similar straight bladed fans, at the 15' mark you get gusts of wind, not a steady breeze, but the gusts are very forceful. I suspect this fan moves the most air of all of those tested
60" Gold Line: At the 15' mark you get the same steady breeze as the 56" Gold Lines, but you also get gusts of wind like a straight bladed fan that are noticeably stronger than the steady breeze. You also get a stronger breeze directly under the fan.
