Hi all, I need your help how can I decide which carbon filter I should buy. I have this technical parameters for my Exhaust Fan:
Voltage: 220V
Power: 550W
Blowing Rate: 18m3
/min
Calibre Of Outlet: 80mm
Wind Pressure:1.70Kpa
Rotating Speed:2800RPM

and the place where I put it my laser is 25m2. I want to buy a carbon filter because the neighborhood where i put it my laser is in the center of the city.

So this is the page where I would buy, so I need your help to choose which one should be http://growshop-mania.mk/category/57/filtri.html

18 m³/min equals approx 1000 m³/h
Try to get the biggest one (3000m³/h)

=> It will have the lowest pressure drop
=> The smaller the filter, the higher the pressure drop, the more the air flow is reduced.
=> You get more activated carbon which will have a longer service live
