Cost-effective Qualification of an NGI and ACI at AB FIA
There are two ways of qualifying and determining the cut-off efficiency of the NGI or the ACI stages; geometrical cut-off mensuration or delta P (dP) measurements.
dP measurements are related to the jet velocities and thus the dP measurements are quick and you get only one value per stage which makes trending straightforward and cost-effective. AB FIA can also repair all types of impactors and have also refurbished spares in stock.
For more information, please see info on AB FIA website.
