ER Vent fan placement
Posted: Tue Jan 17, 2023 2:39 pm
Greetings Great Minds!
I am in the process of repowering a couple fleet vessels and find that I may have to install new vent fans in the engine rooms. The original vent fans were hydraulic drive and were removed 15 years ago but replaced with 24v squirrel cage exhaust fans. If I am to replace these with larger ones, I will go 120v but I'm curious about what you all think is the better placement? There is a vent trunk at deckhead level near the transom and another at the fwd ER bulkhead but it's a vertical trunk to the flybridge level.
Opinions on which trunk to install a fan? Forced air in the deck level trunk or exhaust in the vertical trunk?
Thanks in advance! Calm Seas everyone.
