THE 100 cfm fan if separate from the 440 cfm can-fan thats just to push the hot air out of the lights... The air is being pulled through the filter through a hole that exits my room im pulling air into the room from the outside of the room. the dehumidifier is in the room below the carbon filter in the room and it pulls the hot air from the dehumidifier out of the room. Im getting a smell from cigarette smoke cause thats the only thing I could think of with a strong odor that i could test to try to see if its working and im still getting a smell i have a switch for the fan and I have it turned down to 70% the can filter requires 412 max cfm my fan puts out 440 cfm so at 70% i don't think that is a bad percentage for my fan to be at? Im stumpped
backdraft31485 Reviewed by backdraft31485 on . How do I test My Can 66 Carbon Filter to make sure im not getting a odor? I Just bought a Can 66 Carbon Filter and a can-fan 6inch ho 440 cfm and I tried to test it with cigarette smoke and I could smell it through the other end of the vent hose i have leading out of my room. Im using the filter in a 5 foot wide 7 foot tall by 9 foot long room. im running a 600 watt hps and a 400 watt hps with another fan pushing the heat out of the lights out of my grow room. the can filter and fan are connected together and forcing the air out of the room i have a switch hooked up Rating: 5
