Cleanroom Air Return Solutions

Cleanroom air returns remove contaminated air from the controlled environment, directing it back to the filtration system for cleaning before recirculating. This prevents the accumulation of particles and ensures that the air within the cleanroom remains within the specified cleanliness standards.

Air Return Styles

Low Wall Returns

Low-wall air returns are particularly effective in cleanrooms with turbulent or mixed airflow patterns. 

Raised Air Returns

Raised air returns are ideal for cleanrooms with unidirectional (laminar) airflow, where clean, filtered air flows downward from the ceiling to the floor. This setup is often used in high-grade cleanrooms with stringent cleaning protocols.

Raised Floor Air Returns

Perforated cleanroom floor tiles allow air to be returned underneath the floor to return air chase, providing the best conditions for laminar flow. Raised floor air returns are most suitable for semiconductor and high-tech applications

Custom-Designed Returns

If standard configurations do not meet your facility’s specific airflow, contamination control, or spatial requirements, we can create a custom solution to effectively remove airborne contaminants. Custom solutions allow for optimized air return placement and size, ensuring cleanrooms maintain the necessary cleanliness standards while accommodating your operational needs for:

  • Complex layouts
  • Custom room shapes
  • Tailored airflow patterns
  • Specialized equipment and processes

Air Return Integration with Modular Cleanroom Wall Systems

Our air return solutions integrate with both structural and seamless-style cleanroom construction.

Structural Solutions
