An elastomer (EPDM and NBR-rubber) used in bends, branch pipes and mounting brackets gives a particularly high wear resistance and moderation of the sound level.
Dustcontrol´s bends are designed with a patented radial ridge to spread the impact area of the material and thereby reducing the wear and minimising the risk of blockage. NBR is especially recommended for use with oil and cutting fluids.
