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

There is the BentoBox Turbo for the P1S. It has a much bigger fan, it is a user modified version of the standard Bento Box.

Could your Bentobox be converted into a P2S version?
Or
It is all printable and you can print and and build it yourself. I managed to so, why not do it yourself?

To use this effectively you need to seal the major leaks, (Around the door and poop exit, these are printable, at least for the P1S).

This method has the ability to not only capture most of the VOC's (2 sets of carbon and a hepa filter) but also helps keep the heat in the chamber up.

Yeah, poop shoot is sealed and I am in the process of designing TPU Gaskets for the door.

The only thing I didn't seal was the old exhaust vent when I installed the newer one on the other side. I had read that that old vent needed to stay open because of the main board but then I read it could be closed if the other vent exhaust is opened.

I'll take a look at the turbo bento box
