The Aerosol Distribution and Dilution System ADD 536 was developed by Topas for protection grade measurement in operating rooms according to DIN 1946-4 and SWKI VA105-01 (formerly SWKI 99-3). It provides test aerosol generated by an aerosol generator (e.g. Topas ATM 228) at six different outlet ports with a defined source flow, especially for verification of hospital operating rooms.
Hospital operating rooms are specially designed to avoid contaminations and therefore additional infections of patients during operations. To assure a low level of particle contaminations a laminar air flow is applied to the operating table.
To verify the retention efficiency of this flow regime a verification with a defined test aerosol is required according to the standards DIN 1946-4 and SWKI VA105-01 (formerly SWKI 99-3). For that reason a total particle rate of 6,3 × 109 #/min has to be distributed to six different positions and emitted with a reliable long term stability. From the standards it is also required that this total particle rate is continuously monitored and controlled by a particle counter.
The Aerosol Ditribution and Dilution System meets all these required demands for providing a defined test aerosol with the following features:
The ADD 536 mixes the aerosol provided by an aerosol generator (e.g.: ATM 228) with a defined transport flow rate and distributed it to six vents and a particle counter port.
The operation of the ADD 536 requires an additional suitable aerosol generator (aerosol flow rate up to 5 L/min, particle generation rate > 6,3 10⁹ #/min) and a suitable particle counter (sample flow rate of 2,83 L/min or 28,3 L/min).
