I know of the many threads regarding these two items for lasers. I just thought I would tell everybody what I bought and how they work.
I went with a Grizzly model G0710P dust collector for the exhaust fan. It's about $80 more expensive than the 1 hp Harbor Freight dust collector, but the noise level is about 1/4 (79 dB for the Grizzly, 112 dB for the Harbor Freight; both max ratings; reduction of 10 dB equals half of the noise level). The Grizzly is rated for 537 cfm and 7.2 inches static pressure, and Epilog requires 450 cfm and 6 inches s.p. for the Mini 24. The outlet is a little over 4 inches, but a 5-inch to 4-inch duct reducer from Lowe's fits perfectly on the outlet.
For the air assist compressor, I went with the Master Airbrush compressor from TCP Global. I'm not sure what the model is, but it is listed as "NEW Quiet AIRBRUSH COMPRESSOR w/Regulator" on Amazon. It's 1/5 hp, 57 max psi, 0.7 cfm, and it includes a regulator with an oil/moisture trap. It's super quiet and provides plenty of airflow. I ran a test on the Epilog before I hooked this thing up, and while cutting LaserMax plastic, it made about a 2 inch long flame. With the air assist turned on, there is no flare-up. It did take a couple of fittings to adapt the 1/8-inch threaded fitting on the included air hose to the 1/4-inch push-in fitting on the Epilog, though.
Now, I just have to hard pipe my exhaust to both lasers, and I'll be up and running.
