Blaine Air Permeability Filter Paper - Gilson Co. - GlobalGilson.com
The main application for air filters are combustion air to engines. The filter papers are transformed into filter cartridges, which then is fitted to a holder. The construction of the cartridges mostly requires that the paper is stiff enough to be self-supporting. A paper for air filters needs to be very porous and have a weight of 100–200 g/m . Normally particularly long fibrous pulp that is merceri… Webto define air permeability of the various unusual paper components is of paramount importance. On a more common level, the effec.t of variations and changes in the porosity of filter plug wrapping paper can play havoc with the filter rod pressure drop or with the pressure drop control. provincetown compact
