Hepa Filter Holder for LV-H132 filter and 140mm Fan
Description
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 materials like ABS or other filaments sensible to the temperature variations. (delamination) All is printed in PLA. The Filter work great, remove the fume and the smell from the air, and now I'm can print with more tranquility. this is the filter: https://www.amazon.it/Levoit-Carbone-Sostituzione-Purificatore-LV-H132/dp/B06XNPGNY9/ref=sr_1_13?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=Levoit+lv-h132&qid=1569141199&s=gateway&sr=8-13 This is the fan: https://www.amazon.it/gp/product/B00KESSIUW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 this is the thermal circuit used for drive the fan: https://www.amazon.it/gp/product/B07FHXP8M2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
