Need to get just a little air out of a closed cabinet. The only way is through a small 3" or less pipe. Holovision used to have a small system that used 2" vacuum pipe.
Hoping to figure out something similar, without having to make it myself.
Any ideas, etc would be appreciated.
I installed a flexible 3" duct going from the top of a cabinet to a basement, using a plastic quad outlet junction box, a 12V computer fan, Bosch relay and a wall wart, triggered by the 12V jack on a Denon receiver. Still working after 13 years.
I got the duct from the HVAC guys- it was scrap from what they were doing.
