yeah I can see the light there. interesting way of hanging it inside.
so it looks like your fan and filter are inside, shooting non stinky air right outside. so barely any ducting needed which is not only cheaper, but more airflow. (random info... they taught us in pipefitting school that a 90 degree elbow is the equivalent resistance of 40' of straight pipe when dealing with fluid/air movement)
I like your hanger system too. I need to figure out a way to mount to the tent rails easier than my carabiners that dont open enough for the bar to go into.
I was doing flow testing of each fan and was testing with a smoke machine. before i expanded to 4 fans and 2 liters fit perfectly over 4" fitting if you cut a small slit. essentially giving you air tight. I Believe the pics were taken when i was testing those 2 fittings for leaks. it changed to 4 out 1 in. In that photo was 3 out 1 in setup. went to 6" return. new one will be 8"Curious what those two clear empty soda bottles are for? Great McGiver’g...
That's a lot of air exchange, possibly too much. You want to aim to fully change the air once every 2-5 mins.3x3x6 tent is 54 cubic feet. and I want to evacuate that 3x per minute. so I need a 150cfm fan exhaust?
and its saying that the intake fan should be 2x the exhaust fan?
my 6" fan is good for 240cfm
That's a lot of air exchange, possibly too much. You want to aim to fully change the air once every 2-5 mins.
Personally I'd run a 4" inline fan with a speed controller on the exhaust and a 6" axial fan on the intake, or if you are filtering the intake you could just run a second 4" inline with speed controller on the intake end as well. That would be closer to ideal, and you could use the speed controllers to balance the pressure in the tent.
