What's the max length exhaust hose?

[MedvedTrader]

If I use 5" exhaust hose for an S9, what's the max length that the fan can push through without causing problems? The hose will make a 90 angle and go straight up...

Basically, what I want to do is to run it in the garage, have the hose move the hot air to the garage attic and have the 1000 CFM gable fan blow the hot air outside. Feasible?

2 or 3 metres tops. Always best to have an inline fan sucking there air out aswell.

Ok what is a good, reasonably priced high CFM inline fan?

All depends what country you are in, what noise levels are acceptable etc.

USA, noise - well, as long as it is not louder than the S9 But obviously quieter the better.

This one looks good no? https://www.deelat.com/hvac/fans/ventilation-air-fan-blowers-and-movers/portable-exhaust-fan-ventilation-diameter-8-200-mm-single-phase-110v

Is the 90 degree turn the total change in direction (over a long distance) or are you coming straight from the miner with a 90 degree elbow?

Limit the bends in the duct as much as possible, since each bend represents a then higher fan requirement. If you need to turn 90 degrees, do it gradually and avoid sharp angles.

I noticed you said you are going to send the exhaust up to the attic. What is your setup in the attic, if you can set your miners up in the attic pointing towards the exhaust fan you wont have to worry about ducting.

If you are going to go with the ducting route, here was a thread that came up with some good solutions.
