Rayshen Environmental Pvt. Ltd., we understand that cleanroom air purity is non-negotiable. That's why our Fan Filter Units (FFUs) are engineered to set a new benchmark in cleanroom airflow management. A self-powered, high-efficiency air filtration system, each FFU integrated with a powerful fan module with a HEPA or ULPA filter, delivering particle-free, consistent, and laminar airflow across critical environments.

Designed to overcome internal system resistance, our FFUs ensure reliable contamination control while optimizing performance, energy efficiency, and long-term durability. Whether you are building a new modular cleanroom or upgrading an existing setup,FFUs deliver scalable, serviceable, and cost-effective solutions for industries where air quality defines success.
