Question: Can you open it up and clean the blades?
Document: I would say this this is about as good as it gets these days. It's a med. sized fan that has metal blades and moves air really well.
Yes, this fan is inexpensive but there is not much difference between low and high speed. This fan certainly does push a lot of air though. Maybe I got a dud, but I found no real difference in air flow, speed of the blades and noise level between low and high speed. I ended up returning it the same day I bought it. There's no way you could sleep with that fan running on low.
The metal cage is thin and flimsy and the blades are of very poor quality and workmanship. The fan I received actually had a bent blade, but that is not why I returned it. This new Chinese model is just not good quality and therefore not a good value for the price.I guess this is the way most companies have gone in the last few years. Closed down their American factories and shipped the work off to China. However, I will never understand why the quality has to be so poor.
I purchased this fan as a replacement for an aging Patton 14' fan that has lasted about twenty years. What I liked about the older fan is that it had tremendous air flow,and had a chrome cage and it was quality made.The new Patton fan has a black wire cage around the blades  and has a smaller profile than the old one which is good but the new fan does not put out the great air flow as the old one and it looks much more cheaply made.
we had one before this one and it seemed to be built better. This one seems made cheep.
usually don't leave reviews but I love this fan so I had. for sure recommend this to others. very powerful and we needed a fan in the 2012 heat waves.
i purchasee the max air  20 inch fan.THAY fan is great.if you want a quiet gentle air mover buy something else.if want or need a roon air mover then this is it.this ban is bordeline industrial/it IS an hd fan.noy quiet almost noisy.
You would think the Chinese model could be made just as good as the old American models with the same parts and technology. But obviously this company has decided to cut all the corners and pass off junk under a company name that used to mean quality.I just purchased a used Patton fan on ebay for $56(not including shipping) and was glad to pay that price for something that I know will be far better quality.
We use these fans in our barns to move air and they are fantastic. We have two in three barns and keep 2 spare on hand. Thank you for getting these items for us.
We bought a similarly sized Patton fan 18 years ago, when living in an apartment without air conditioning. At the time, the price was very similar to the current price of this fan. We were very impressed (and grateful!) for the way that thing moved air through the apartment and cooled things off. Over the years, it had a lot of use.
Answer: Yes, it only takes a few seconds. It has a few clips to open and you can wipe them Dow.
