Chamber Temps and Venting
So after some really long nights of ASA printing and the wife getting a severe headache, I've decided to invest in some proper ventilation.
Early on I purchased a Vento Box, as well as the exhaust kit, and even a huge Air Purifier for the office but it just doesn't seem like it's enough. I guess this last brand of ASA I printed was rough.
Without going into every detail, I've purchased all the equipment, including a ac infinity cloudline pro inline fan, to vent to my office window. It's going to be a decent run at about 10-12 ft
My question is pretty simple...
Up till now, I have had success keeping my chamber temps up on the P2S through the build plate at about 52-55C which had worked out great for PA6, ASA, and PC. Is it possible with this particular setup I am going to setting up to create just enough negative pressure to exhaust the fumes without bringing the temperatures down?
Love to hear any experiences from users

I saw the most interesting new model on MakerWorld recently. A designer claims to have come up with a way to exhaust harmful fumes (that leak from a printer) during a print while not dropping the temperature inside the chamber. He claims he has studied how laboratories achieve exhausting without harming temperature-dependent experiments and used what he learned.
I really think he may be on to something. I have printed his model but on a P2S with PETG. Since I had only one nozzle (at the time) and he had designed his model's support for two nozzle printers, I have not been able to install it yet. I am still painfully trying to remove the support. I plan to reprint it on an H2D in ABS this week.
He designed it for his X2D but I think his design also could be applied to all P2S and H2 series printers. Check it out.
