We can build clean rooms with high cleanliness, but we often cannot ensure that the cleanliness of these clean rooms dynamically meets the standards. I have been invited to many factories for on-site diagnosis. I have found that many factories have similar equipment, but their cleanrooms have never met the dynamic cleanliness standards after passing the empty and static cleanliness tests. It is obvious that the problem lies with the people. I saw on site that workers did not change clothes according to regulations, did not perform prescribed actions in the air shower room, and even some female workers put on makeup and entered the clean room. It can be imagined that if human activities, the major source of pollution in cleanrooms, are not regulated and controlled, how can cleanliness standards be met?

Pay attention to the relevant methods for selecting purification workbenches

The general classification of clean workbenches in the market is: economical air filters with indicators lower than the standard and poor appearance; Fans are generally made of domestically produced ordinary fans, which have good performance at the beginning of operation, but their performance cannot be guaranteed over time; In order to reduce costs, external air filters are often not used; The control system is simple, but the appearance is not good.

Ordinary type air filters that use raw materials and technology in production, with performance similar to that of the product; The fan adopts mid-range products and also includes Sino foreign joint venture fans, which are relatively reliable. However, most of them are not designed for the special needs of clean workbenches, so the uneven airflow during long-term use is its characteristic; The overall performance is relatively good, but the control system is relatively simple, and glass doors are usually manually operated. Type, filters used in the entire product or multiple applications; The fan used is designed according to the characteristics of the clean workbench; The main performance is higher than that of the ordinary type; The control system has been specially optimized for users: most glass doors are driven by electric motors, and there are sensors inside the box that can reflect the working condition of the filter to improve product reliability. A few products use embedded control systems. Don't just focus on the quotation of the clean bench. When choosing a clean bench, the quotation is an important factor.

However, considering that the clean workbench is a device used, maintenance and upkeep costs are also relatively high. A characteristic of the clean workbench here is that its air filter is a consumable, and dust accumulates on the surface of the filter during use, causing an increase in air resistance and ultimately leading to the filter being scrapped, resulting in system failure. Once such a phenomenon occurs, the product will immediately alert you, but you cannot be sure if the same problem has occurred with medium and low-end products. Do you know that the extra money spent on replacing the filter is troublesome and costly? Therefore, most medium end products use the method of adding a pre filter to extend the service life of the filter, while most low-end products only symbolically add a piece of cloth.

Pay attention to cleaning and disinfecting the clean workbench

A clean workbench is a special type of workbench, and the product will spend a lot of space telling you how to clean and disinfect it. A good clean workbench will have many accessories, most of which are related to cleaning and disinfection. The selected clean bench should at least be able to install ultraviolet lamps for disinfection and sterilization. You may want to ask the supplier what they have done for customers' cleaning and disinfection. If they find that a certain product is not suitable for cleaning, they do not need to consider it. It may have good performance but low performance, but it will be very inconvenient to use.
