Quotation is an important factor when purchasing a clean bench. However, if the ultra-clean workbench is considered to be a long-term use equipment, the maintenance and maintenance costs are also high. Therefore, the full life cost of the product should be considered. Here, the ultra-clean workbench has a prominent feature. Its air filter is a lossy product. During use, the surface of the filter will accumulate dust, which will increase the wind resistance. Finally, the filter will be scrapped and the system will be ineffective. Once such a phenomenon occurs, high-end products will immediately alert you, but you can't know if the middle and low-end products have the same problem. Do you know that the extra money spent on buying filters is a troublesome and expensive thing? Therefore, most medium and high-end products use a pre-filter method for extending the life of the filter, and most low-end products are only symbolic plus a piece of cloth.
