I am not, just the ac infinity standard filter box, of course to try to limit the cleaning of the exhaust fan blades, the box came with a high effenciency one that i am changing today to a stardard merv 11 to see how that does, 20 different roasts and i think it may have reached its limit, i will go outside to day to feel the air from the vent to double check flow.
How are you attaching the merv13 filters behind the grease traps?
This setup is very similar to mine! Almost identical and I am also get smoke inside. Did you ever find a solution?
New here to the community. Just ordered my roaster yesterday. In the process of figuring out a ventilation setup. I noticed you mentioned you were getting smoke. Curious if you have the AC Infinity box filiter as the other member does a few posts above.
So, I just roasted again and watched very closely this time. I put a blast door on the cooling tray and kept it closed during roasting. This drastically improved air flow out of the roaster! However, when I opened the blast door on the cooling tray and the cooling tray was on power 4, it was so strong that the pressure in the wye pushed the roaster exhaust down. I could see visible smoke pushing past the sides of the vent hood. When I slowed the cooling fan speed down to 1, it was slow enough to draw both. Then after the smoke cleared from the roaster, I increased the cooling fan speed. I use a cloudline 6 fan with 4" duct. I’m considering switching to 6" duct and maybe even running a separate passive duct for the cooling tray since its so powerful.
No I don’t, however, that just filters the smoke going outside and protects your fan.
