SOCIETE' JOB FILTERS AUSTRALIAN REPORT T. 44
I have compared the contents of the Report from
Australia with those obtained here in 1966 - letter to
Purchasing Department, 7 th December, 1966.
The structure of the filters are identical. The
physical properties are compared in the following table:
Australia Southampton
Filter Rods
Pressure drop' (cm W. G. -) 3.35 3.7
weight (mg/cm) 89 Not Available
Filter Tips
Filtration Efficiency 48 42
for T. P. M.
Pressure drop (cm W. G. ) 6.7' 6.3
Filter length (nn) 20 is
Although the samples differed slightly in pressure
drop, the filter performances as measured in the two
calculations are in close agreement.
The general conclusions are similar in both reports.
