Bay Ventilation Project

July 16, 2016, 01:02:17 am

I am working on installing a ventilation blower in the center bay for the inverter and I also want to ventilate the adjacent battery bay and charger without having to install a second blower.

While waiting for the blower to arrive, I decided to make a venturi extractor to put in the battery bay, which will be fed by the blower hose from the center bay, then the hose will exit thru the battery bay floor exhausting air from both bays.

It's made with approx $6 in PVC plumbing parts - a 3" x 2" adapter, a 2" x 1.5" adapter, and some small lengths of 1.5" and 2" tubing, and some sheet metal supports.

Got the blower yesterday and have been testing it. With more than a couple of feet of hose after the venturi it loses effectiveness, probably due to added air resistance in the hose. Working on Rev B today with some ideas for improvement.
