Lasko Ultra Box Fans | 2000-01 vs. 2007-08

Comparing 2 Lasko Ultra branded box fans, similar models from almost a decade apart. There's a lot of debate among collectors regarding the use of these two motors. I have reasons to like both, but I'm glad I did this comparison as the differences between the two are a lot less than I initially thought. The old Marco shaded pole motors are extremely nostalgic to me as I grew up with a 3733 fitted with one of those motors. The sound of that motor and blade combined is one of the most nostalgic sounds of Summer to me. However, shaded pole motors are very inefficient, and paired with the high energy costs in my area, I often thought it would be better to run the newer model instead as it has a more efficient PSC motor. While the newer PSC fan did turn out to have a higher efficiency rating in terms of CFM/watt, it was not as significant of a difference as I was expecting. In fact, it only costs about a quarter per day more to run the old fan on low compared to the new one on low. While that certainly does add up over the course of an electricity billing cycle, and when multiple fans are used, it's nowhere near as much as I was expecting. Lasko was able to get a few more CFM/watt out of the newer units using the PSC motor, but it's not all good. It comes at the cost of a louder fan with a more disagreeable sound (personal preference). The volume of air is also lower than the old one due to the blade not being as substantial, so while it is more efficient, it also moves less air. This would be most noticeable when used to move air through a window. The performance of the units to circulate air throughout a room is probably comparable. One thing worth nothing I forgot to mention in the video: the newer Ultra is a bit of an odd configuration. Lasko tends to use 2 motors and 2 blades to make up the majority of the fans they sell. This fan seems to feature the more powerful motor, but the less substantial blade. Another comparison I'm very curious about, which may yield more favorable results to the newer one, is something like the WeatherShield Select which has both the more powerful motor and more substantial blade. Here are the specifications I came up with during the video. The specifications are listed from low speed to high speed, Power Consumption (watts)/Operational Cost per 24 hours (dollars, based on my latest utility bill's rate of 31c/kWh)/Air Flow in CFM/Efficiency in CFM per watt/Loudness (dBA) respectively: 2000-02 model: Low - 98/$0.73/1,112/11.35/53 Medium - 124/$0.92/1,465/11.8/59 High - 180/$1.34/1,765/9.8/67 2007-08 model: Low - 67/$0.50/1,015/15.2/55 Medium - 88/$0.65/1,274/14.5/63 High (Full Power!) - 110/$0.82/1,534/14/68
