Product Overview: One Cleanroom Workbench
A cleanroom bench is a purification equipment that provides a dust-free working environment, featuring ease of use, simple structure, and high efficiency. It is designed to meet the demands of cleanliness in local work areas within modern industries, optoelectronics, biomanufacturing, and scientific research and testing fields. The HS type ultra-clean bench is a vertical直流 local purification unit. Within a specific space, the indoor air passes through a pre-effect filter and is then forced into a static pressure box by a low-noise fan. After that, it goes through a high-efficiency air filter and the clean airflow is emitted horizontally and uniformly, carrying away dust and biological particles, thus achieving a hundred-class cleanliness in the operation area and forming a sterile, high-purity working environment.
The Wuxi Yijing YJ-HS Horizontal Workbench features an energy-saving rear-mounted variable air volume supply system, paired with high-performance, long-life efficient air filters, achieving a filtration efficiency of ≥99.995%. The spray-painted diffuser plates ensure uniform air distribution, creating a horizontal laminar flow from the inside out to achieve purification. It is widely used in various industries such as food safety, healthcare, biotechnology, electronics, cosmetics, dust-free operating rooms, aerospace, and more. Customizable options include single-person horizontal ultra-clean benches, double-person horizontal ultra-clean benches, and standing operator ultra-clean benches. Available in full stainless steel ultra-clean benches, exhaust dust ultra-clean benches, and three-person extra-wide ultra-clean benches.

Product Technical Parameters:
Cleanroom benches are purification equipment that provides a dust-free working environment, featuring ease of use, simple structure, and high efficiency. They are widely used in various industries and scientific research departments, such as electronics, defense precision instruments, meters, pharmaceuticals, tissue culture, and laboratories.
Operating Principle:
The HS type clean bench is a horizontal airflow local purification unit. After the indoor air passes through a coarse filter, it is forced into a static pressure box by a low-noise fan and then evenly discharged through a high-efficiency filter, creating a clean airflow that passes through the work area at a uniform speed to remove dust, forming a high-purity working environment. It employs an energy-saving, rear-mounted variable air volume supply system, equipped with high-performance, long-life high-efficiency air filters, achieving a filtration efficiency of ≥99.995% (sodium flame method) for dust particles ≥0.5μm, ensuring the workspace meets the US Federal Standard 209E (100-class purification standard).
Many professionals are unaware of the distinction between biological safety cabinets and clean benches, believing that their uses are quite similar.
Actually, there are many misconceptions. Clean benches and biological safety cabinets have significant differences. Firstly, let's define the two in terms of principle.
Biological Safety Cabinets: Used for handling pathogenic bacteria, molds, and yeast; the operation area is under negative pressure, simply put, it draws air out. However, the pathogens are not directly extracted and discharged outdoors; they are filtered through the top trap of the cabinet. They are classified by exhaust air volume into 50% outside exhaust, 75%, and 100% outside exhaust types.
Cleanroom Bench: Equivalent to a miniature clean room, it achieves a Class 100 clean level according to the U.S. Federal Standard 209E, with extremely high cleanliness. Simply put, it draws air in from the outside, maintains positive pressure inside, and keeps the operation area at a higher level of purification through a pre-high-efficiency air filter.
From the above definitions, a conclusion can be drawn: the exhaust of biological safety cabinets, and the supply air of clean benches. Below, a comparison will be made through two working principle diagrams, making it clearer to understand.
