DIF O.T. Ceiling filtration system for operating theatres

Air filtration and distribution for operating theatres The operating rooms are the hospital areas where it is required the most accurate control of the environmental sterility. As the highest source of bacteria is coming from the medical staff during the operation, the highest concentration of contaminants is located around the surgery table, increasing the risk of wound infections. The concentration of microrganisms is taken as an index of sterility of the environment and it is expressed in number of particles carrying microrganisms. The choice of the air filtration and distribution system for...

The DIF-O.T. ceiling filtration system is the result of the know-how developed by SagiCofim in the techniques of air filtration and distribution for operating rooms. This system, thanks to H14 efficiency absolute filters, allows a controlled air distribution above the operating theatre and represents the best choice to control the contamination levels. Its peculiarity is the capability to guarantee the sterility levels in ISO Class 5 Operational Simulated, i.e. during the intervention, with the surgical team fully operative. This result is achieved thanks to a sophisticated supply air concept...

• Unidirectional airflow from the ceiling with differential velocities • Air filtration through absolute HEPA filters • No physical guides or air curtains are required. • No uncomfortable drafts in the occupied zone • No contaminated air induction in the critical zone • Class ISO 5 “Operational simulated” guaranteed, during the surgical room operation, certified according to the Swiss Standard SWKI 99-3. • Perfect tightness by means of a reverse liquid seal around the edge of the filters Air return grilles are located in the four corners of the room in two locations: at the floor and at the ceiling...

• Complete system for ceiling air filtration and distribution, factory assembled and tested. • Standard dimensions: 3,2 m x 3,2 m x 0,4 m, nominal air flow 9.500 m3/h 1 • Holding structure, filter frames and top plenum made of AISI 304 stainless steel. • HEPA filters, H14 efficiency, with different performance and colours (V1, V2, LV) designed to obtain a decreasing air velocity from the centre towards the perimeter of the surgical theatre. • Patented flow equaliser to achieve uniform and constant air distribution over the whole surface even with low velocities. • Perfect tightness guaranteed...

High performance system Fast recovery time A DIF-O.T. fitted in SagiCofim mock-up room was tested by specialised personnel using an OPC (Optical Particle Counter) and a biological concentration counter. The diagrams show the test results in terms of 0,5 micron diameter particles and CFU (Colony Forming Units). These data were confirmed during the tests carried out on site and certified by independent laboratories. Colony Forming Unit CFU/m3 tempo - minuti tempo - minuti The diagram shows the results of the particle count above the operation table. The test has been conducted using an OPC following...
