چکیده
Abstract A set of mono-disperse aerosol generator was designed to meet the requirement efficiency testing for high particle air filter. The generation tests and performance were conducted by using evaporation–condensation method, with NaCl solutions at different concentrations as condensation nucleus respectively DEHS, DOP, PAO–4 reagents. results show that three reagents can generate particles strictly controlling various parameters which affects performance, where size range is 0.33–0.36 μm 0.35–0.37 DOP 0.34–0.36 aerosols lager than 10 6 cm –3 . characteristics generated through such method basically conform requirements

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
HEPA EXHAUST FILTER IV HEPA SUPPLY FILTER I / All
A microbiological survey of the effectiveness of class II (laminar flow) 'safety' cabinets found in the UK in the last six years is recorded. Only two of the nine units tested approached the containment of aerosols achieved by a good class I (exhaust protective) cabinet. The others were potentially hazardous if used with pathogenic material. The National Sanitation Foundation and the British St...
متن کاملHigh-efficiency particulate air filter test stand and aerosol generator for particle loading studies.
This manuscript describes the design, characterization, and operational range of a test stand and high-output aerosol generator developed to evaluate the performance of 30 x 30 x 29 cm(3) nuclear grade high-efficiency particulate air (HEPA) filters under variable, highly controlled conditions. The test stand system is operable at volumetric flow rates ranging from 1.5 to 12 standard m(3)/min. R...
