TAS.OP Laminar flow system for Operating Theatres Ecoefficiency for Indoor Air Quality

Laminar flow system for Operating Theatres TAS.OP Filtration SagiCofim Air filtration and distribution system for operating theatres, with vertical unidirectional air flow, suitable for operating rooms from ISO 5 to ISO 8 class, according to ISO 14644. A proper return grilles positioning is recommended to obtain the highest indoor air quality level in the whole room. H14 HEPA filters manufactured, tested and packaged in controlled clean environment Advantages Suitable to operating theatres for critical surgery in ISO 5 class and for light surgery in ISO 7 or ISO 8 class, according to ISO...

Laminar flow system for Operating Theatres TAS.OP SagiCofim Structure The distribution plenum is in stainless steel AISI 304 with one or two side air inlets, whose size is designed to have a maximum air inlet velocity of 3-4 m/s for a proper air distribution inside the plenum itself. According the ceiling size, the plenum can be supplied in one or two parts to be assembled on site. Filters holding frame in stainless steel AISI 304 to avoid any risk of corrosion, ensuring the perfect planarity and air tightness for the whole system’s life. The perforated diffuser, also made of AISI 304 stainless...

Laminar flow system for Operating Theatres TAS.OP SagiCofim Air flow rate vs air velocity design TAS.OP laminar flow system suits all the most used International Standards. In the following table the design air flow rate to achieve the minimum required air velocities according to the design Standards or Guidelines TAS.OP Design air flow rate [m3/h] Testing and validation Two dedicated ports are factory mounted to make all the testing and validation procedures as easy as possible. • HEPA filters pressure drop: a good filtration directly into the AHUs (typically G4 + F9 + H13) is required to make...

Laminar flow system for Operating Theatres TAS.OP Technical data Air exhausting and ventilation effectiveness It is recommended to exhaust 6570% of the total air flow from the floor level and, the balance, from the highest part of the walls, by installing four grilles in the lower part and four smaller grilles on the upper part of the walls. By following this rule, the overall ventilation effectiveness would be improved, helping the supply air flowing from the ceiling to the exhaust grilles to keep a stable and uniform direction, from the surgical table to the walls, protecting the patient and effectively...

Laminar flow system for Operating Theatres TAS.OP SagiCofim The air recirculation can be designed in two different ways: Recirculation To reach and maintain the proper cleanliness class (typically ISO 5 according to ISO 14644) and to keep the CFUs concentration below the requested level (typically 5-10 CFU/m3) in operational, a big amount of air is needed. To achieve the proper air quality inside the operating theatres and, at the same time, to reduce the energy consumption for cooling/ heating the total air volume, the most used solution is to have a minimum amount of fresh air and then a dedicated...

Laminar flow system for Operating Theatres TAS.OP Technical advice 2. One or more makeup air AHUs to supply the total needed amount of fresh air to all the operating rooms and a “built-in” recirculation system above the false ceiling and directly connected to the filtering ceiling plenu

Laminar flow system for Operating Theatres TAS.OP Filtration SagiCofim Tender text TAS-OP Plenum-type laminar flow-style diffuser for clean air supply in operating rooms. The air, duly filtered through H14 HEPA filters, will play a major role in: • Airborne contamination dilution • Moving contaminants from cleaner to less clean areas, reducing the risk of contamination over the surgical table • Temperature and humidity control • Dilution and removal of waste anesthetic gases The structure is totally made of AISI 304 stainless steel, for easy cleaning and corrosion-free long operating life The...
