Exhaust / Carbon Filter question, need advice...

Hey everyone, let me try to explain a little. I’m in the process of designing a room within my basement.. dimensions are 4’ wide, 6’ deep and 7’ high (or 168 cubic feet).. I’m looking at the AC Infinity Cloudline S6 fan rated at 347CFM for exhaust pulling through a Can-lite 6” carbon scrubber which is rated for 600CFM (blown directly outside) and will be running a passive intake with ambient temps in the room that it’ll be pulling from at about 66-70F. I will be running 1 - 600w HPS (only 4x4 of the built room will be utilized for grow area, the other 2 feet will be sealed off with panda plastic to create an area that I can enter the first door to the room built, close the door behind me and then open the panda plastic so I am able to be inside the room with the door never being opened in order to keep constant negative pressure) From my calculations this should be more than sufficient for the size space I will be using, but would it make sense to go bigger on the fan and filter setup and bump to an 8”? Maybe just go with the 8 inch fan and keep it dialed down to about 50-60%? What do you guys think?

Thanks

I'm using a T6 for a similar area, but no filter. I run a separate stand-alone fan/filter scrubber in the space.
The T series has the controller, and it works great.

I have it set to Auto lower high-temps by ramping up fan speed to max of 4, IF the temp exceeds 79. Then it ramps down to 0 once below 79.
The same can be done for humidity - but not both at the same time. Very quiet, unless at 9 or 10.


In the winter I have it pulling cool air from veg into flower. No AC required.
Hot months, I flip it around and pull AC cooled air from semi-sealed flower room into Veg.

I like the idea of the controllability from the T series, but I also like simplicity of the S series as there is less components to malfunction/fail.. I’m kind of old school in a sense I would rather do things the hard way lol...

I’m in a similar sized space (5x5x8 and I run a Hurricane 435 cfm fan on a variable switch so I can run the fan at partial speed. I’d rather run a higher capacity fan at lower speed than run a lower capacity fan at full speed. It tends to be quieter with less vibration because it’s not running full blast.

I like the sound of that T6 though.....cool technology.

Are you happy with the 435? What does your setup look like (intake, lighting, etc)? Temps?

I’m very happy with the Hurricane. I have a 5x5x8 tent, 1000 watt lamp, 8 inch intake at the bottom of the tent, 6 inch air cooled hood and a new 6 inch phat filter. I only need to crank up the fan speed to full when the 1000 watts is running. I can run at lower speeds when running my 600 watt bulbs and ballast. My tent temperature stays at 83 and room temp is 72. I vent my tent out to another room.

For many growers it's a challenge maintaining consistent temperature, and humidity levels.
At 59...I love old school!
