Air Compressors Dust covers and promoting rust?

[Submariner1]

My new air compressor, (that will get infrequent usage, but hopefully will last me out) is parked in between a lawn mower and a Dewalt Table saw (has dust control, but the fine dust escapes everywhere). I also use a 2100 watt router so same thing.

I kept the huge but thin, plastic bag the Compressor came in, but I vaguely recollect someone saying covering equipment in a plastic bag, in an unheated garage seriously promotes rust, i.e. best to let things breath.

In exchange for me resurrecting the wife's incredibly complicated, swiss sewing machine, she knocked up this cover in really heavy duty cotton drill ( she just had lying around). Works perfectly ... just drops on or lift off ... so no dust on compressor air intakes etc.

It will do the dust prevention perfectly, but if this was then covered with the plastic bag; does that defeat the objective of not using plastic?
only asked as it would be easier to shake off a plastic bag.
Plus is it true covering kit in a plastic bag will cause really rapid rusting?

I wouldn't worry so much about dust on your compressor.

10 years I've had my ex hire compressor in my dusty workshop with nothing more for a filter than a bit of random foam I had lying around

I wouldn’t use the plastic. I expect it's obvious but just make sure the outside of your cover is always the same side i.e. don't reverse it and put the dusty side on the inside.

I have a hacked down remnant of the top of an old (cotton) army tent as a cover for my lathe and that has always worked very well over many years.

I have also knocked up covers in cordura for my welders and plasma cutter for when they are not in use (probably not as good as breathable cotton but I have some rolls of cordura and it seems to work OK). Haven't done anything for my compressor though.

Thanks I will bin the plastic, think it could promote condensation.

Only thought about it, because the saw can generate piles of sawdust which would fall straight onto the compressers cooling cowling.
and the wife knocked it up in 15 mins, just testing the sewing machine after my repair.
