Over the last decades, we have successfully equipped thousands of operating rooms and our customers have enjoyed the quality of our systems for many years.
CG³, the third generation of laminar flow ceilings from MANN + HUMMEL, combines our proven experience in clean air ceilings with the latest technology, unmatched quality and cost-effective management.
CG³ meets today's increased demands for performance, flexibility and quality while minimizing cost of ownership with low power consumption.
A special aluminum profile construction allows for the perfect integration of the CG³ system with media bridges, surgical lights and ceiling suspensions, allowing the medical team to work seamlessly with surrounding equipment.
