Flowhood with custom order HEPA
    #25943518 - 04/19/19 11:37 AM (5 years, 8 months ago)

I am about to place an order for a custom built HEPA filter to build a FH. https://www.kochfilter.com/Products/HEPA%20Filters/BioMAX%20HEPA%2099.999
I want to go for a 3'X3'X6" plywood sided 99.999% high capacity unit with pvc coated separators and stainless steel faceguards. I haven't decided whether or not I want gaskets or flanges. I will update this as I build it.

Dont get the high capacity, it claims to be 1.5" starting resistance on the brochure pdf which is very high. Most fans aren't suited for that high of a resistance and won't blow much air. You would need 900 cfm @ 1.7" resistance with a prefilter on a 36x36 High Capacity filter VS only 1.2" resistance with a standard capacity + prefilter. The standard separators are fine IMO. Facegaurd on the exit size is always a good option if it's not  a pro hood that already has a grate. Adds like $50 per side or so, exit only side is probably enough if you are careful during install.

Personally I find that 30" tall is plenty tall enough for anything. 24" tall can be enough if you are more careful for certain g2g or bag to bag type activity to not break the stream. 30x30 is a good size. 30x36 pretty tight.

Good info sandman. I suppose just the one side for the faceguard for sure, but i want the pvc coated separators for extra sturdiness if I travel. I expect I will move it once or twice

Can you give a generalized price for that when you get your quote? Sounds like something I may need to start saving towards.
