Vacuum feedthrough

With optimum value for money

Vacuum feedthroughs with leak rates < 10-8 mbar l/s are mostly realized with ferrofluidic seals.

For such cases MAFU offers a much more cost efficient solution. Vacuum compatible oil is filled in the gap between two axial shaft seals. This guarantees a very good seal rate as well as a significant lifetime extension.
