Thanks for all your supports,
Firstly as i worked on many CBRN Protection projects i know that HEPA doesn't filter VOC, I have a fiberglass prefilter before fan which catches most of the particles that HEPA is considered for catcthing runaway aerosol particles to take odour away (i was wrong)...
It's a DIY spray booth, i've also added HEPA filter to exhaust. So i need both airflow and pressure. I don't have enough space to use of those grim fans. I have two 280 m3/h and one 150 m3/h fan, trying to make combinations to maximize airflow
Hi,
I have three general questions
1. I know that "n" fans in series increase n times airflow, "n" fan parallel increase n times pressure
2. Is this rule only valid for identical fans
3. And what if if i connect two fans parallel and another one serial to those
