Are there brands of bath exhaust fans made to be installed in suspended ceilings ? Many have no brackets. Do I use a suspended ceiling light box bracket ? Or do some fans come with brackets adaptable to ceiling grid ? Thank you
 
30-inch piece 2x4 or even 1x4 on either side. Set it down 1/2 or 5/8 like you would for sheetrock. Gives you something to tie support wires to, if needed, as well.
 
3/4” piece of ply the same size as the ceiling tile, place on top the tile. Add eye bolts (not screws) so it is independently supported. edit: 1/2” would work, also.
 
I've installed many speaker cans in hung ceilings which is the same situation. What I did was I had the "tin knockers" on a job make me a bunch of 1-1/2 x 30" sheet metal angles. I laid two across the T bar grid either side of the can and put a couple of self drilling "peanut" screws through them into the can.

You can do the same thing with perf angle from any hardware store or big box. You can loop your support wires through the holes too.

The important thing to do is to keep the weight off the ceiling tile because it will sag.

Could be a problem in a fire rated structure................
 
Thanks. Fire rating is an issue at this job but I notice the GC has exposed wood studs in all the walls above the ceiling so I'm assuming the tiles are fire rated. (He drywalled the studs only up just past the sus. ceiling level.)
 
Probably a stupid question....the inspector has been monitoring the remodeling of this State Farm office and for example has had the GC do things like double firecode drywall on the wood ceiling joists (there are apartments on the second floor). The suspended ceiling is below that. I don't need a special fire rated bath fan do I ? Is there such a thing ?
 
Plastic parts? Not sure what you are asking.

Fart-fans have the little wings/brackets on one side to mount to a joist. You would be anchoring it by whatever means was allowed (from above) with the same offset as for sheetrock. Turn the little support tabs up on the opposite side and away you go. If the tiles are in, trim it out and exhaust accordingly, done.

The problem is that often the tile can’t be installed once you put the fan in. So the tile under the fan need to go in first which makes it a little more difficult mounting the fan.
I have also seen a piece of the grid left out so that the tile can be slid in under the installed fan.
This is especially true for the integrated can light fans - they practically lay on the tile.
