The differences between the 2 are as follows.
Seal material: Select from NBR or FKM for the FQ1 series and NBR or fluororesin for the FGD series.
Housing material: Only stainless steel 304 is available for the FQ1 series.

For the seal kit part numbers and the seal replacement procedure for CHKD/CHKG, CHN, CHSD/CHSG/CH2E(W), CH2F(W), CH2G/CH2H, and CHA(W) series cylinders as well as the seal kit part numbers for CHQ(W)B and CHA(W) series cylinders, refer to the “Maintenance Parts List,” which can be found here.
sonic conductance C x 5 = effective area S[mm2]
Cv x 18 ≈ effective area S[mm2]
Formula: (0.3 + 0.1) x 5 = (0 + 0.1) x V
V (volume before change) = (0.3 + 0.1) x 5 ÷ 0.1 = 20 L (ANR)
