[labnetwork] Pirnaha Exhaust Condensation

[Anthony Christian]

Hi Adam,
You could introduce a course filter to catch vapours, however, it’s going to get eaten by the Piranha too.
Another option, which is more expensive, would be to introduce an air flow to the extract to keep the vapours moving through the ductwork to your scrubber.  Not a quick fix though.  Maybe as simple as adding a duct opening and allowing the extract to pull additional air into the duct, keep the airflow it slightly turbulent but not too much or it will get noisy.

Thanks,

Subject: [labnetwork] Pirnaha Exhaust Condensation

Hello everyone,

We are having issues with our exhaust ducting from our piranha deck. We have a connection where it attaches to the main ducting which is caulked and taped but it seems that no matter what we seal it with, piranha which has condensed in the ducting, eats through it. I am wondering if anyone uses a filter/screen of some kind to condense the vapours before going out the exhaust line. Thanks in advance for any advice!

Regards,
Adam
