"HSB" baffles

Protection of vacuum pumps against premature damage

Frequently, in high-vacuum applications for the production of complex layer systems, critical gases or gas mixtures are used. Depending on the process, it may be necessary to evacuate these gases with the high-vacuum pump. In many cases, it is unavoidable that such gases or vapors condense as solid particles in the pump, significantly impairing the pump’s function or, as in the case of turbomolecular pumps, even leading to their destruction.

The HSR protective baffle condenses these harmful gases before they enter the turbomolecular pump, thus protecting it against functional impairment or even destruction.

Function
