Workshop Overview
Product Showcase
High-Efficiency Air Supply Outlet
The high-efficiency air supply outlet is the terminal filtration device of a cleanroom air-conditioning system. It is mainly used to evenly distribute clean air that has been filtered through high-efficiency filters (HEPA/ULPA) into the cleanroom, ensuring that the space meets the required cleanliness level, such as ISO Class 5 (Class 100), Class 1,000, and other cleanroom standards.
Air Shower Room
The air shower room is an essential purification device for personnel entering cleanrooms and dust-free workshops. It offers strong versatility and can be integrated with various types of cleanrooms and clean manufacturing facilities.
Before entering the workshop, personnel must pass through the air shower room, where powerful streams of purified air are sprayed from rotating nozzles in multiple directions to effectively and quickly remove dust, hair, particles, and other contaminants attached to clothing.
By reducing contamination caused by personnel entering and leaving the cleanroom, the air shower room helps maintain a high level of cleanliness. The two interlocked doors also function as an airlock system, preventing external pollutants and unfiltered air from entering the clean area.
Through effective removal of hair, dust, and bacteria carried by personnel, the air shower room ensures strict cleanroom standards and supports the production of high-quality products.
Laminar Flow Cabinet
A laminar flow cabinet is an air purification unit designed to provide a localized clean environment. It can be flexibly installed above process points that require high cleanliness levels. A single laminar flow unit can be used independently, or multiple units can be combined to create a continuous clean zone.
The system mainly consists of a cabinet body, fan, high-efficiency air filter, damping layer, lighting fixtures, and other components. The cabinet is typically made of 304 stainless steel and is widely used in the medical industry.
The product can be either suspended from the ceiling or supported on the floor. With a compact structure and convenient operation, it provides an efficient solution for maintaining high-cleanliness working environments.
Pass Box
A pass box is an auxiliary device used in cleanroom environments, mainly designed for transferring small items between clean areas, or between non-clean areas and clean areas.
By reducing the frequency of opening cleanroom doors, the pass box helps minimize the risk of contamination and maintain the cleanliness level of the controlled environment.
The working surface is made of stainless steel with a smooth and clean finish. The two doors are equipped with an interlocking system to prevent simultaneous opening, and the built-in UV ste
rilization lamp effectively helps prevent cross-contamination during material transfer.
