DIF-OT Ceiling Filter The optimized laminar airflow

When hygiene is crucial The operating room is the most critical zone of the hospital. The operating theatre must be a clean room to protect the patient. The ventilation and the filtration system must ensure an ultra clean air environment to keep the patient alive and healthy. The infections are caused by various contaminants. The main risks of contamination are coming from the staff and the equipements (direct contamination or from the indoor air (indirect contamination). The air is the most important source of infection therefore it must be controlled to limit the risk. What are the...

Ceiling filtration system The DIF-OT ceiling filter supplies clean filtered air into the operating area. The air diffusion method is unidirection airflow or vertical laminar airflow, appropriate for highest risk applications (ISO5 class requirement), compared to the turbulent or mixed diffusion system appropriate for lower risk applications (ISO7 class requirement). The vertical laminar airflow flushes the operating area with ultra clean air achieving ISO5 classification, pushing contaminated air outside the operating area. The ceiling structure comprises a stainless steel plenum and HEPA...

DIF-OT, the optimized laminar airflow for high clean rooms classification There are differential flow velocities decreasing from centre towards system’s perimeter to provide a dynamic barrier between the operating table and the outer zone. This differential air velocities optimizes the air treatment and the air cleaning in different operating areas : surgery bed (most critical area), surgi- cal staff area and outer area (rest of the staff and equipements). Benefits of laminar airflow : ISO5 class at rest (acc. SWKI99-3). Short recovery time. No draft in the comfort zone. Benefits of...

DIF-OT, ceiling structure and filters Structure comprises plenum box and filter fame in AISI 305 Stainless Steel. HEPA filters are performance colour coded (V1, V2 & LV) to match velocity. Patented flow equaliser to achieve uniform and constant air distribution over the whole surface even at low velocities. Airtight construction and Dynamic sealing of filter edges. Filters HEPA filters H14 efficiency, individually scan tested, according to EN1822. Uniform velocity over filter face to within ± 2.5 % using the synthetic cloth equaliser No additional flow stabilisers are required. Very low...
