Our History

When Cleanroom Techniques first began, our primary focus was on air filtration. However, as we grew, we started receiving inquiries about refrigeration and air conditioning, which inspired us to expand our expertise. We began by installing and servicing room air conditioners and soon ventured into industrial ventilation and refrigeration. Our extensive research led us to specialize in manufacturing and process ventilation engineering. To further enhance our capabilities, we brought on an in-house mechanical engineer to design and produce detailed drawings, allowing us to manufacture air handling units. We also established partnerships with leading Chinese companies to source key components, such as controls, air filters, and monitoring systems. Today, we are proud to be one of the smallest businesses offering comprehensive solutions for the pharmaceutical and medical industries.
