Replying to your letter ref:CEM/HML. of Oct. 27th. We like the porous pot filter but we find that it gets choked too soon. We also find that the plate filter seems to be doing very good work. At the moment, therefore, we are not contemplating a change. We should be interested to know, however, how the porous pot filter compares with with that of the plate, for price. Yours faithfully, For Rolls-Royce Ltd. | ||
