Is this available in 60Hz 240V?

I don't know about the 60 hz 240 volt

Will this work in crawling space of an attic? Crawling space size is approximately 75 sq ft.

I don’t see why it wouldn’t... it has a humidistat to automatically regulate the moisture. It only turns on when needed to suck out the humid air. Just keep in mind that you don’t want another vent or space open to the humid air, or it will just keep the problem going by sucking in moist air...

will this fan work in a basement 800 sq ft X 6' ?

I'm not sure about the dimensions but overall the fan works well.

do not know if fan is reversible, but I know it never shut off all summer and all of fall
