Filters

Filters

Filters are advanced passive devices designed to suppress electromagnetic disturbances, limit conducted emissions, and improve power quality. They protect sensitive systems against the effects of harmonics, overvoltages, and resonance, ensuring safe and stable operation.

Our portfolio includes harmonic filters for network protection, sine-wave filters for motor protection, as well as filter + transformer sets dedicated to inverters in DC/AC grids and energy storage systems.

Filters are used across a wide range of industries: industrial automation, energy, railway, mining, marine and offshore industry, as well as in installations with drives and power electronic systems. They are designed for operation in harsh environmental conditions – including high humidity, dust, and vibrations.

We stand out thanks to our individual design approach – each filter can be tailored to specific customer and application requirements. Our products comply with applicable standards and meet strict quality criteria. With many years of experience, production flexibility, and an extensive reference portfolio, we are a trusted partner in the field of filtering solutions.
