ANA1 series: It features 40 dB (A) noise reduction, which is the highest of the 3 silencers.
ANB1 series: It features 38 dB(A) noise reduction, which is slightly lower than that of the ANA1 series, but the discharge flow rate is larger by 1.4 to 2.2 times. Compared with an ANA1 with the same male thread size, the external dimensions are also larger.

The high noise reduction style silencer ANA1 keeps the noise level inside a plant below 85dB(A) with a noise reduction effect of 40dB(A). Series ANB1 has a noise reduction effect of 38dB(A) and has a larger effective area with the same port size as series ANA1.
