All filters cleaned by PPSL are fully tested and the results compared with the "as new" technical specification published by the filter manufacturer. Flow Testing is undertaken as standard:After the 'Bubble Point' is established the back pressure is the recorded at a air flow rate of 10LPM. This gives an indication of the mean pore size of the filter and can be used to assess the integrity and performance the filter will give online.
