Note: The water pressure drop curve is measured base on clean water, the water pressure drop measured at
site may be different because of different water quality.
Test condition: Octave band level noise is tested in noise chamber whose background noise level is
11.5dB(A), during actual use, due to environmental noise or other reasons, the real noise
may be different.
