The High Efficiency Air Outlet, also known as HEPA Air Outlet, is a terminal air supply device in cleanroom HVAC purification systems. Installed on the cleanroom ceiling, it houses a high-efficiency filter and delivers treated clean air uniformly into the cleanroom. It is one of the key equipment components for maintaining cleanroom cleanliness levels. High Efficiency Air Outlets are typically used in conjunction with duct systems and air handling units. They are suitable for cleanroom environments ranging from ISO Class 5 to ISO Class 8 and are widely used in pharmaceutical, biotechnology, electronics manufacturing, hospital, and food processing industries.

Compared to a Static Pass Box, it has larger external dimensions for the same internal size and a higher manufacturing cost. Dynamic pass boxes are divided into two subtypes: Laminar Flow Pass Box, which provides vertical laminar airflow in a top-supply

The negative pressure weighing chamber is a specialized local purification equipment used in pharmaceutical manufacturing, microbiological research, scientific experiments, and other similar settings. It provides a vertical unidirectional airflow, with some clean air circulating within the operating

Purified laminar flow cover is an air purification unit that can provide a locally clean environment，It can be installed flexibly above the process points requiring high cleanliness.

The Cleanroom Aluminum Pass Box is a material transfer device installed between clean and non-clean areas, or between zones of different cleanliness levels. Its primary function is to minimize cleanroom door openings during material transfer, prevent cross-contamination, and maintain the cleanliness classification of different areas. Constructed with an aluminum alloy frame, the pass box offers lightweight design, corrosion resistance, aesthetic appearance, and durability. It is widely used in pharmaceuticals, biological laboratories, electronics manufacturing, food processing, and other industries requiring strictly controlled clean environments.

he Multi-Person Air Shower Room is a high-capacity contamination control solution designed for simultaneous use by 2 to 6 personnel or for cleaning small cargo passing into cleanrooms.
