Pre-filter and separating units

Adsorption of humidity and decomposition products

On the assumption that contaminated or humid gas is in the circuit breaker we recommend the use of pre-filters between switchgear and service cart.

Moisture, gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special dry and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected.

Our pre-filter units are available as portable or mobile version. The filter cartridges can be exchanged easily.
