Dayton 5EAJ8 50-Pint Dehumidifier
A Dayton branded 50-pint dehumidifier model 5EAJ8.
I believe these were manufactured by Soleus Air, which is not a good brand. Soleus Air has had numerous safety recalls over the years for their dehumidifier catching fire. I know the recalls effected specifically the smaller 25 or 30 pint units, I'm not sure if it affects these larger units as well. Either way, if enough shortcuts were taken in the smaller units to cause fires, I'm sure some shortcuts were taken in these models as well. Not good.
Despite the potential safety hazards, this is quite a good machine. I wouldn't run it unattended, but it works very well. The bucket is particularly large yet still fills quickly. This is one of very few dehumidifiers I've used that's able to drop the humidity down into the 30% range. It makes the air so dry it feels like heat is running. I'm not sure on the exact age but I would put it somewhere around the late 2000s to early 2010s. Definitely one of the earlier pieces of R-410a equipment of this form factor.
