Product Description

EBS TFE (equivalent to Denka 174)

EBS manufactures their our own line of TFE Cathodes, which are the MET models. These MET/TFE Cathodes are:

– Lower in costs and an alternative to Denka, FEI, etc..

– Are not gun conditioned, which means, they have not been run with extraction of electrons and the start-up process for the customer is going to take longer.

-Not all operating data are available.
