This is a simple air extractor, I've used it for my printer cabinet.
It is build for fit the LV-H132 Hepa filter, I chosed this filter becouse this it integrate an hepa filter and an Active Carbon filter in a single unit, with a modest cost.
I've used a Noctua NF-A14 iPPC-2000 IP67 PWM and a cheap Thermal PWM circuit, for pwm speed regolation, powerd by a old 12V 2A power supply (ex 3,5 HDD box).
I've used a PWM tecnology for a soft speed variation, for minor impact when I print material
