Colour-Indicating Silica

When the silica turns pink, it is time to replace the unit.

The breather features multiple 0.3-micron filters, which clear solid particulate out of the air as it moves through the unit. The silica beads, on the other hand, absorb harmful moisture, preventing it from entering the machinery.

The top foam pad retains oil mist from the air as it is led out of the container, thus ensuring none of the mist reaches the silica or the outside environment.
