What is the installation sequence of cold dryer filter? Generally speaking, one is installed in the front and two in the back of the dryer. The filter is combined and configured according to the principle of "first coarse and then fine", and the order cannot be reversed.

        The precision of q-class precision filter, p-class precision filter and S-class precision filter are 5 μ m, 1 μ m and 0.10 μ m respectively. Therefore, the installation sequence is that q-class precision filter is installed at the front, p-class precision filter is installed at the second, and S-class precision filter is installed at the third.
