I like the design of these fan walls on big units as opposed to squirrel cages with belts, the things that make them nice are there is less maintenance, and there is a lot of redundancy if one of them goes down! This one motor has a bad bearing and needs to be replaced but I can isolate it by a plug and the other motors will compensate to maintain static pressure, the negative is they are really expensive but you pay for convenience, quality, and efficiency. #teachme #pm
