Description:
The paper discusses tests of air filter particle-size efficiency for diameters greater than 1 micrometer. valuation of air cleaner efficiencies in this size range can be quite demanding, depending on the required accuracy. uch particles have sufficient mass to require consideration of sedimentation and inertial losses. he challenge aerosol is usually generated by dispersion of a dry powder or by liquid spray. n-duct particle measurements are preferred to extractive instruments because of particle loss in sampling tubes. arge particles are also sensitive to nonisokinetic sampling effects.
