TouchDown
Is it Friday yet?
So, we have a lot of unused clean room space in our plant, with HEPA filters everywhere. Depending on the space, they are either fan driven or ducted. Majority of one's that are available are fan driven (lots and lots).
I am in charge of a project where we're are looking at building a modular cleanroom in a space where I'd like to set it up with ducted HEPAs for better control as we make the new space a new VAV zone since there are a lot of heat sources in the space and we want to make sure it's held at the correct space setpoints.
My question is this, since I have soooo many of these fan driven one's and I want to use ducted HEPAs, is there a large difference between the 2? Could I just not hook up the fan and duct one of these fan driven one's in? It looks like they have a sheet metal fitting that could be modified to accept a duct, but does leaving the fan in place increase your pressure drop across the HEPA, creating a supply air problem? Could I remove the fan blades and then use them?
We're just looking at saving cost and with these things laying around, I would like to reuse them, but I don't have time to "test" to make sure they'll work like I want.
Any feedback is appreciated. I guess I could call the HEPA mfg. as well??? But, it's Saturday and I'm watching cartoons with the kids.
