The buffing process is synonymous with polishing. Technically “buffing” uses a separately applied abrasive. Usually the product to be treated is metallic but could be plastic or glass. It could be plated e.g. with a chrome layer applied. The buffing action is normally applied via a rotating mop or brush, often with a mild abrasive fluid applied; alternatively soaps or waxes may be used to aid the buffing process. The surface being treated will be change and minute particles of host material may become dislodged. Extraction is required to maintain air quality in the workplace environment. There may be hoods or the work may be done by robots in a booth. Close coupled extraction is essential both to minimise splatter but also to limit the amount of extraction flow required. By far the greatest part of the contaminant loading in the extracted air will be mop or brush fragments and aerosols of the waxes or fluids applied. The very nature of the sticky contaminants means the ductwork should be a straight and short as possible. RotoClone N is the ideal collector.
