Clean Rooms

Modular Clean Room Design For Manufacturing Flexibility

Ensuring quality control while balancing long-term construction with short-term cutting, welding, or surface prep and spraying tasks is an ongoing logistical challenge. Navigating these cellular workflows is critical for aerospace OEMs, ship and boat manufacturers, and for operations conducting prototyping and R&D.

How do you cost-effectively isolate manufacturing processes to keep damaging elements out and clean air around each workpiece?

Bring Compliant Clean Air to On-Demand Work Spaces

Duroair’s retractable clean rooms create clean air environments wherever they are needed. We combine our DuroRoom™ retractable enclosure with our DuroClean™ engineered exhaust system into one flexible, cost-effective solution for portable clean rooms and isolation rooms.

Duroair modular clean rooms can be placed anywhere in a manufacturing facility without having to install supplementary ductwork — or pay for ongoing air make-up costs. Our portable, retractable enclosures with non-vented air filtration can be engineered for large or small self-contained work environments, wherever and whenever needed.

Whether isolating a manufacturing process from the larger work environment (negative pressure) or protecting a process from contamination (positive pressure), our DuroRoom™ and engineered filtration systems help guarantee worker safety from toxic dust and fumes, while reducing operating expenses and increasing productivity.

Benefits of Duroair’s custom portable clean room design includes:

  • Increased workflow efficiency for stop-and-start R&D processes
  • Reduced material handling by not having to transport large workpieces to a dedicated clean air space
  • Eliminated need for expensive equipment and installation for air make-up
  • Laminar or turbulent airflow as required
  • Unsurpassed control of isolated work environments, including pressure (positive or negative), humidity, and temperature air flow patterns, and harmful dust particulates and gaseous contaminants
