Note 1) Use the moisture control tube in a line with a refrigerated air dryer and a mist separator installed
in the upstream compressed air line. The condensation prevention performance may be lowered
depending on the quality of the supply compressed air (oil, dew point).
Note 2) The inner sleeve is already mounted and cannot be removed. If the inner sleeve comes off,
re-insert the sleeve before mounting the fitting.
Note 3) Do not cut the tube.
∗1 Use the product in an operating environment where humidity is
as low as possible.
∗2 The value at which the moisture control tube is bent or flattened at 20°C.
Be careful not to bend or flatten the tube and the inner sleeve even if the
value is more than the minimum bending radius.
