A clean bench is an enclosed workbench that is controlled to prevent dirt and dust in the air and surrounding environment from adhering to or contaminating items that are being worked on. Clean air that has passed through high-performance air filter (HEPA filter) flows directly to the item being worked on, which makes it possible to maintain a high degree of cleanliness even in locations that have a low level of cleanliness. They are used mainly in factories and laboratories.
Although there is a similar device called a "safety cabinet", clean benches also provide an internal positive pressure. Therefore, it is possible to create a very clean state that is free from dust by discharging air to the outside of the enclosure.
Various functions are added to clean benches according to the work to be performed.
Clean benches are box-shaped enclosures that consist of a desktop and walls on the front, top, and both sides. Workers place their hands inside the enclosure to perform work. Air pulled in from the outside is filtered to remove dirt and dust, and then the clean air is sent inside the bench.
There are two types of clean benches: a horizontal blower type that blows air forward from the front surface, and a vertical blower type that blows air downward from the top surface. In the case of horizontal blowers, the air might collect around the worker's arms or the equipment, preventing a sufficient level of cleanliness. Therefore, Matsusada Precision clean benches primarily use vertical blowers. Horizontal blowers can be provided upon request.
The structure of clean benches is determined according to regulations in JIS B9922.
It is very easy to use a clean bench. After washing your hands thoroughly, use alcohol to disinfect your hands and then all of the items to be used inside the clean bench. Turn on the filter switch, and insert your hands into the insertion ports to perform the work. There are also clean benches that have a completely open front, or that have a shutter to be pulled down. If the clean bench has a shutter, pull it down as far as possible while still allowing you to perform the work.
Before choosing a clean bench, clearly determine how you intend to use the equipment. Clearly identifying the intended use will make it easier to choose the appropriate product.
Matsusada Precision clean benches can be designed as needed according to intended use and available installation space. Our products use strong yet lightweight aluminum frames, and are equipped with casters so they can be moved easily after installation. They can be introduced easily and at low cost.
