delta-P for inlet air filter, multistage centrif blower?
(OP)
I'm trying to characterize the system curve for an existing wastewater aeration system based on centrifugal multistage blowers installed in 1991. Specifically, I'm interested in the pressure drop across the inlet air filter. The blower is rated 125 HP and delivers about 1800 scfm drawn from atmospheric conditions. Limited information exists at the facility, and the blower manuf (Lamson, G-D) could not quantify the inlet filter performance. They referred me to a filter manufacturer named "Industra" but I could not find them online. I feel like I'm recreating the wheel here.
Are there typical ranges of pressure drop (in-h2o or psi) for inlet air filters, clean and dirty condition? Are there rules of thumb? Can you refer me to a manufacturer who could answer such a question?
