Trakumas S1, Willeke K, Reponen T, Grinshpun SA, Friedman W.Author information1Department of Environmental Health, University of Cincinnati, OH 45267-0056, USA. AbstractIn this study, methods were developed for comparative evaluation of three primary dust collection methods employed in vacuum cleaners: filter bag, cyclonic, and wet primary dust collection. The dry collectors were evaluated with KCl test aerosols that are commonly used in filter testing. However, these aerosols cannot be used for evaluating wet collectors due to their hygroscopicity. Therefore, the wet collectors were evaluated with nonhygroscopic test particles. Both types of test aerosol indicated similar collection efficiencies in tests with dry collectors. The data show that high initial collection efficiency can be achieved by any one of the three dust collection methods: up to 50% for 0.35 microm particles, and close to 100% for 1.0 microm and larger particles. The degree of dependence of the initial collection efficiency on airflow rate was strongly related to the type and manufacturing of the primary dust collector.

Collection efficiency decreased most with decreasing flow rate for the tested wet collectors. The tested cyclonic and wet collectors showed high reentrainment of already collected dust particles. After the filter bag collectors had been loaded with test dust, they also reemitted particles. The degree of reentrainment from filter bags depends on the particulate load and the type of filter material used. Thus, the overall particle emissions performance of a vacuum cleaner depends not only on the dust collection efficiency of the primary collector and other filtration elements employed, but also on the degree of reentrainment of already collected particles.PMID: 11669383 [PubMed - indexed for MEDLINE] Publication TypesComparative StudyEvaluation StudiesResearch Support, U.S. Gov't, Non-P.H.S.MeSH TermsAerosols/analysis*Air MovementsCentrifugation/instrumentationDust/analysisDust/prevention & control*Equipment DesignFiltration/instrumentation*Household Articles/instrumentation*Housekeeping/methods*Particle SizeWaterSubstancesAerosolsDustWaterOther Literature SourcesCOS Scholar UniverseMiscellaneousWater - Hazardous Substances Data Bank

Small garage workshops gather dust and dirt quickly, but many dust collection systems are too costly or large to install in smaller shops. A secondary option is to build your own dust collection system using a shop vac, which can be picked up for less than $100.The Wood Whisperer breaks down the leading budget dust collectors, with the Dust Deputy Cyclone being the winner. win a robot vacuum cleanerIt also happens to be the least expensive, at $60. kirby vacuum cleaners corporate officeIn addition to the shop vac which powers the system, and the Dust Deputy Cyclone that separates the dust, you'll need some 2 1/2" fittings, flexible tubing, clamps, and blast gates to complete your new creation.reviews on hoover upright vacuum cleaners

Cleaning dust from your workplace’s air is vital to helping reduce employee exposure to potentially dangerous levels of contaminants. Proper dust collection can mean increased visibility and reduced costs for the cleanup and maintenance of your facility. It also helps you comply with health and air emission standards, reduces the possibility of causing a nuisance for your neighbors and can even help you recover valuable by-products from the air. This series of articles is about builing my second small dust collector. The idea is to have something that's half way between a bigger dust collector and a shopvac.
