Hi all. I’m looking to replace this furnace draft inducer fan we use for cooling a very expensive avionics computer in a stationary simulator as detailed here. FASCO’s datasheets have no info on CFM or SP that I can find, so it's difficult to know what CFM & SP to look for in a replacement fan. I am about to test what pressure the fan is producing in our duct here this afternoon, so I can at least give you that later this afternoon. These often run for 12+ hours straight, 5 days a week. So as you can see, something reliable as possible (We are installing this new protection system that will better protect the computer in the event of a fan failure as detailed in the post linked above, so we don't need to get crazy with aerospace or NASA-level mission critical fans)
Unlike whoever originally designed the fixture this all goes on, I’ll mount the new fan either shaft vertical or shaft horizontal, whatever makes more sense for the fan I end up with.
We’d also like it as quiet as possible. I'm trying to decide if I might want an ECM (or other speed controllable motor via a 4-20mA or 0-10V signal). We might want to just keep it as cool as our chosen fan is able to by running it full speed at all times, but on the other hand, reducing noise in this space is always preferred if all else is equal.
Cost is actually not a big concern but the real challenge here is that they ideally went one made in the US (Stupid, I know, but some of our contracts require it).
The fans that come to mind for me here are the small inline duct fans from the likes of Fantech, Soler & Palau, and Continental(CFM). Continental being the only of those based in NA (but I still have to check with Continental on where they’re manufactured), does anyone know how reliable any of their small fans of this general size https://continentalfan.com/wp-conte..._Duct_Fans_Wholesale_Ventilation_Products.pdf are? It looks like their AXS EC and Elicent AXC series are made for continuous duty.
I'm open to large PC fans too (probably the centrifugal blower-style ones rather than axial, but we'll see once I test the static pressure of the current fan here in a couple hours)
Anyone have other ideas? Or know of other US-made fans in this general CFM & SP range?
