The HS-D Series.​​​

Waterseparators to protect gears from water droplet ingress while allowing them to breathe.

HS-D membrane filters are an excellent alternative to adsorbers when liquid water is a challenge but moisture is not a problem. With the help of an ePTFE filter in the core of the robust polyamide housing, the gear oil is protected from contamination by water, even if the gear is used outdoors or cleaned with water.
