8.4 Characteristics in change of Lossnay Core over time
Two Lossnay Cores were removed from the 18 Lossnay LS-200
installed in the Meiji Seimei Building, and the static pressure loss
and exchange efficiencies were measured. The comparison with
the initial value is shown on the right. The appropriate air volume
for one Lossnay Core is 500 m

/hr of this value.
8.5 Conclusion
(1) Changes in the characteristics of the Lossnay Core after approximately eleven years of use and an estimated 28,000
operation hours were not found.
In numerical values, the static pressure loss was 150 to 160 Pa at 500 m
exchange efficiencies had decreased slightly at above 500 m
remained in the measurement error range.
(2) Looking at the appearance, the Core surface was black with dust, but there were no gaps, deformation or mold that would
pose problems during practical use.
