Yes, easily. Think muffin fans, as in desktop computers.<br>
Many sizes & speeds and voltages. I'd go with 120V AC, or
with 12V DC powered with a wall-wart 12V supply.<br>
Keep to lower flow models to keep noise down. Keep to larger
(3" or 4") diameters, again to keep noise down (smaller fans with
same airflow are much noisier). Use a 2" T to pull the air off,
and adapters to change up to a size accommodating the fan.</p>
<p> I'm currently using a 4" 120V muffin fan to ventilate our
utility room, to keep the cat-box odors down. Works great.<br>
I've also got a couple 12V DC fans ventilating our small
greenhouse - powered directly with 5Watt solar panels. When the
sun shines, the fans run.<br>
If your local electronics shop or Radio Shack doesn't have what
fits, look at digikey.com, search for fans. Many Many options and
a selection facility.</p>

<div>Quite a few years ago I imported four Ekologen
EcoDry toilets from Sweden. These are porcelain
toilets that send the poop and the pee into separate
(installer supplied) vessels. While the idea was
extremely inspiring, the reality has been somewhat
less fantastic. The poop falls through an 8" pipe
into a bucket, and a handful of sawdust is dumped
after. That part works beautifully. Not once has
there been any smell. <br>
<br>
</div>
The urine is sent through a 1-1/4"(?) flexible hose
that came supplied with and is attached to the
porcelain unit into a vertical 2" ABS pipe and from
there into a bucket that sits outside in the free air,
and is dumped as needed. <br>
</div>
The problem - the only problem - is that the urine smell
in the bathroom can be strong. Visitors, e.g., higher
usage, sends the smell index shooting up, whereas
day-to-day usage by one person doesn't cause much
discomfort. And of course folks' sensitivity/sense of
smell varies a lot. <br>
<br>
</div>
The toilet was supplied with a micro-flush button which
would have sent a small amount of water (1/10 of a liter?)
through the urine section. I initially hooked this up, but
I discovered a casting flaw in the porcelain which sent a
bit of the water not out the drain but through a crack not
visible from any angle I could devise onto the floor. I
talked to the manufacturer about that but they were not
helpful, did not take any useful responsibility, so we've
always used a small cup to splash a bit of water to chase
the urine. <br>
<br>
</div>
Recently I swapped in a wood toilet seat/lid for the OEM
plastic one which allowed me to attach a gasket between
porcelain toilet and seat and between seat and lid. This
made a disappointingly small difference to the ambient odor.
<br>
<u><br>
</u></div>
<u>So now to my question:</u> do low-power small fans exist
that you could recommend for installation in the 2" ABS vent?
My sense is that these exist but I am not familiar with any
specifics. <br>
</div>
<div>My hope for this fan would be that it would create a very
slight negative pressure in the bathroom, drawing any smell
out the vent rather than letting it escape into the room.
Ideally it would also be switchable from inside the bathroom.
<br>
<br>
</div>
<div>Or perhaps some of you have experience with his or similar
situations and can recommend other strategies I've not thought
of?<br>
<br>
</div>
<div>Thanks very much.<br>
