I cannot comment on the exact diameter of the flange as I do not have the unit anymore. However if you are attaching this directly to a fan you should purchase a noise reduction clamp found here Noise Reduction Clamp 6 quot
My one complaint with my experience was the prefilter straps could have been tighter. This can be remedied by folding a small section of the strap over itself then stapling it.
PLEASE NOTE: (This has occurred with all name brand filters I've experienced) There will be charcoal dust in the box and on the unit when taken out. More importantly there will also be a large gust of dust debris when you first pull air through it. My suggestion is you vent the air directly to the outside of your house at first for a good couple of minutes. It's also ideal to take a break and move the filter around to help the loose dust exit (tilt it horizontally/vertically), then continue to pull air. This will help keep dust from accumulating within your grow room.
Just purchased the 6x24 version from Amazon Prime and they did not provide a discrete box for shipment. Keep this in mind.
Note that I purchased the 4x20 lo profile and then made the mistake by going to the 4x8 model.
1) Even though the 4x20 is rated for 125 cfm and the 4x8 is rated at 150 cfm, I noticed a significant decline in air flow. The 4x8 (150cfm) seems to allow less airflow than the 4x20 (125cfm) :::::
2) The flange on the 4x8 was significantly large which the 4 inch ducting that did fit the 4x20 would not fit the 4x8. It seemed to be an inch or half do big of an opening.
Out of my return period and without the original box (as it was discarded to early by me, I did not anticipate these issues)
I went to Phresh's web site, their contact method only contains an email form. I'm still waiting a week after two submissions. There's no phone number.
My MacGyver side can try to make it fit but the less air flow has me defeated. I wasted 50 bucks !!
NOTE" Be sure to blow the filter out with a blower, or fan, or air jet from a compressor to remove the fine black carbon dust prior to installing or bringing into your home. The dust can be very hard to remove from carpet and or other materials. Be careful! especially when first opening the package that contains the filter itself. IMO take it outside to blow it out before bringing it inside. Very Important as with all carbon filters.!
I still wouldn't put this in top of a grow tent "unless its a high dollar Gorilla type tent that can handle the extra weight. But for the cheaper tents, NO WAY! Im pretty sure people do, but I wont. I haven't had to clean it yet, but can tell from past experience that this will be just as easy. For a quick clean you can spray fresh R/O water, or tap, through the filter, and rotate it while spraying. For a deeper clean, I remove the flange and all the carbon in the filter and put it in a draining style bucket with a mesh screen over the drain, then with water spray all throughout the carbon pellets until the out going water is really clear. Then let dry, repack the carbon, re install the flange, I don't re-rivet, I just use either sheet metal screws or Gorilla Duct tape. The cleaned filter will sometimes last sometime from 1/8-1/3 longer just from cleaning. but is a big process and can get quite messy.
Works well on unwanted odors as well particulates in the air.
Works best in drier areas,used in shop with a lot of dust cleared air well, used in basement after flood reduced mold and fungus smell better the more dry the basement became.
Does EXACTLY WHAT YOU THINK
I can paint, weld, use solvents ect...
ANY THING causing a terrible stink will be scrubbed out. No complaints of grinding smell from the family. Panasonic makes a wiper quite fan series. Pass though design 200cfm and higher. DC motor uses very little energy. VERY QUITE I forget to turn it off after grinding. The Panasonic with this filter is perfect. The two can be coupled directly to eachother. Can't beat the price or quality.
