In modern surgical environments, maintaining a sterile atmosphere is critical. During an operation, airborne particles and microorganisms can easily enter the surgical field and increase the risk of infection.

A Laminar Flow Ceiling System creates a controlled sterile airflow zone above the operating table. Clean air filtered through high-efficiency HEPA filters flows downward in a uniform, low-turbulence pattern, continuously pushing contaminants away from the surgical area.

Compared with traditional ventilation systems, laminar airflow ceilings provide a stable and controlled airflow environment that significantly reduces airborne bacterial contamination.

Hospitals worldwide rely on laminar flow ceiling systems to:

Reduce surgical site infections (SSI)

Improve operating room cleanliness levels

Maintain a stable sterile surgical environment

Support advanced surgical procedures

The Operating Room Laminar Flow Module (MLS) is a ceiling-mounted air supply system designed specifically for hospital operating theatres and medical cleanrooms.

Installed above the operating table, the module supplies sterile air through multiple high-efficiency HEPA filters and distributes the airflow evenly across the surgical field.

The ceiling system is constructed using AISI 304 stainless steel or powder-coated steel, providing durability, corrosion resistance, and easy cleaning for medical environments.

Smooth surfaces prevent dust accumulation and allow fast disinfection, ensuring compliance with hospital hygiene standards.

The system also incorporates sound-absorbing materials to reduce ventilation noise, improving the comfort of the operating room.

Laminar flow ceiling systems operate by supplying HEPA-filtered air vertically downward over the surgical area.

Air first passes through high-efficiency HEPA filters that remove more than 99.95% of airborne particles. The clean air then flows through perforated laminar panels that distribute the airflow evenly.

The airflow moves downward at a controlled speed of approximately 0.24–0.30 m/s, forming a stable laminar airflow pattern with minimal turbulence.

This vertical airflow continuously pushes airborne contaminants away from the surgical field and directs them toward return air outlets around the operating room.

By maintaining this controlled airflow environment, the system creates a localized sterile zone that protects the patient and surgical staff during procedures.

Our laminar flow ceiling systems are designed to meet the strict requirements of modern hospital operating rooms.

Key specifications include:

Module sizes of 2600 × 1800 × 500 mm and 2600 × 2400 × 500 mm

Equipped with 6 to 8 HEPA filters

Filtration efficiency up to H13 (99.95%)

Outlet airflow velocity of 0.3–0.45 m/s

Suitable for Class I and Class II special clean operating rooms

The system uses removable perforated laminar panels, making maintenance and filter replacement simple and efficient.
