Products Introduction

• FFU clean glove box, using HEPA or ULPA filtration technology, enhances the protection of experimental products by removing airborne particles and powder in the glove box. It generally also comes with a high-efficiency, high-performance, high-quality gas purification system that automatically removes water and oxygen molecules, providing an inert atmosphere with purified O₂ and H₂O. Equipped with high-efficiency filters, and fans from the top of the FFU (closed loop) to suck in the gas and return the clean gas filtered by the primary and high-efficiency filters to the glove box.

• Filter glove box systems are available in open-loop, closed-loop and adjustable flow configurations. They can also be configured as positive pressure to protect the products in the glove box, or as negative pressure to protect the personnel outside the glove box.

  • Function

     • Adjustable flow filter glove box systems offer the most versatility and are best suited for applications that require both open and closed loop circulation. Adjustable valves allow you to quickly switch modes and easily connect to external supply and exhaust systems.

     • Closed loop filter glove box systems continuously filter and circulate the air inside the glove box without any ambient air. They are ideal for applications that require low particulate and controlled gas environments. They can be combined with process gases such as nitrogen to maintain a low humidity, low oxygen environment within the enclosure;

     • Open loop filter glove box systems include inlet and outlet filters. The inlet filter removes micro-pollutants from the outside air drawn into the glove box. The outlet filter captures fine particles in the exhaust gas, safely exhausting into the room. The single pass configuration introduces filtered air into the enclosure and is therefore not suitable for applications that require low humidity, low oxygen, or similar controlled gas environments;







    Applications

    • 100/10 class clean glove boxes are widely used in water-free, oxygen-free, dust-free ultra-pure environments, such as: lithium-ion batteries and materials, semiconductors, super capacitors, laser welding, brazing, material synthesis, OLED, MOCVD, etc. The ultra-low particle environment also makes these devices suitable for other material protection applications, such as microelectronics, optics, cell culture, medical devices, micro propagation, genomics, proteomics and cell biology;
