STERIS Corporation - Helping to provide a healthier today and a safer tomorrow.

CLEANSUITE® Operating Room Ceiling System

  • Helps mitigate the risk of airborne particles
  • Improves OR air quality by 1,000x that of traditional site-built, laminar-flow ceiling systems that conform to US FED STD 209E CLASS 100,000/ISO8
  • Prefabricated structural frame installs six times faster, and at a cost up to 40% less than traditional laminar-flow ceiling systems built onsite
  • Enables precise placement of ceiling-mounted surgical equipment (lights, booms, monitors, c-arms) to create a complete hospital ceiling solution


Product Overview

CLEANSUITE features a single large-diffuser system that delivers gapless laminar airflow to minimize turbulence and gently guide particles away from the surgical site. High-performance diffuser grilles provide unidirectional flow, directing airborne particles and contaminants away from the patient and OR staff while encompassing the room in HEPA-filtered air. CLEANSUITE’s standard particle count of 100 particles/ft3 provides a ceiling solution that achieves the ISO Class 5 cleanroom specification.

CLEANSUITE is 6x faster to install and up to 40% less cost than traditional laminar-flow ceiling systems built onsite.



Prefabricated Operating Room Ceilings

CLEANSUITE offers simplified connections that eliminate the need for on-site welding and also minimize labor for Heating, Ventilation, and Air Conditioning (HVAC), medical gases, and utilities. Its structural steel frame fits tight spaces and tight construction timelines.


future-ready for the modern operating room

Designed to be an Operating Room ceiling system that grows with your needs, CLEANSUITE's grid modularity makes future OR renovations simpler and less costly. Easily move or add equipment around the cleanroom ceiling grid without excessive OR downtime. Internal and external truss systems and compatibility with all ceiling-mounted equipment – not just equipment manufactured by STERIS – allows for seamless mounting of surgical lights, booms, monitors, and C-arms.

How is CLEANSUITE more economical than traditional laminar-flow ceiling systems?

Traditional laminar-flow ceiling systems are built on-site. Because CLEANSUITE is a prefabricated modular system, it’s delivered as a whole. Its structural steel frame fits through a standard 36” doorway, and simplified connections eliminate the need for on-site welding and labor for HVAC, medical gases, and utilities.

How does CLEANSUITE support infection prevention efforts?

There are numerous ways that pathogens may contaminate the surgical field. Contamination sources in the Operating Room may include equipment, instruments, the surgical team, OR traffic, and air quality. Published clinical studies and professional organizations such as Association of periOperative Registered Nurses (AORN) agree that airborne squames, or skin scale particles, shed from the patient and personnel in the operating room are the primary source of bacteria that cause infections in the surgical suite.1,2 At 100 particles/ft3, CLEANSUITE is a solution that achieves the ISO Class 5 cleanroom specification.

Is CLEANSUITE only compatible with STERIS equipment?

CLEANSUITE is compatible with all ceiling-mounted OR equipment – not just equipment manufactured by STERIS.
