The goal is to maintain about 1 pound of pressure above ambiant between the blower and the intake of the filter. This generates the even flow through the filter. -- Paxton Hoag Astoria, OR USA Billy wrote: Ah - that brings back a lot of memories. I spent a lot of time in that factory, even before it opened. Took part in the opening ceremonty, including the Shinto blessing (the priest was flown over from Japan.) Was sad to see it close. The Hillsboro factory was one of the last high volume disk lines in the US. Only pilot lines left now. Billy
