Active Harmonic Filter
Our Latest Active Harmonic Filters are ideal for small to medium size industrial and commercial loads delivering 90-450A optimization per unit. Each unit can be tailored to sites specific requirements and thanks to our built in metering system from Go Monitor, the AHFs can also be connected to for remote monitoring.

Comsys ADF Range
Comsys ADF Range
The COMSYS range of Active Dynamic Filters is developed to enhance power quality in low- and medium-voltage electrical systems by actively reducing harmonic distortion, correcting reactive power, balancing unbalanced loads, and minimizing voltage flicker. These filters continuously adapt to changing network conditions and use advanced sensor-less control technology, removing the need for external current transformers and simplifying installation. As a result, the COMSYS ADF range provides an effective and flexible solution for maintaining stable, efficient, and compliant power systems.

Revcon RHF Range
Revcon RHF Range
The REVCON RHF harmonic filter range is engineered to control current harmonics in three-phase power systems supplying non-linear equipment such as 6-pulse variable frequency drives. By significantly lowering current distortion levels, the filters support compliance with harmonic standards including IEEE 519, while maintaining high system efficiency and avoiding DC-link voltage reduction or drive derating.
The RHF range uses an advanced multi-stage filtering approach to attenuate a wide spectrum of harmonics and is available in passive, active, and hybrid versions to suit different network conditions. With a compact footprint, broad power coverage, and suitability for applications such as HVAC, water and wastewater facilities, industrial plants, and DC charging infrastructure, the RHF range provides a reliable and energy-efficient harmonic mitigation solution.

Circutor AFQ Range
Circutor AFQ Range
The Circutor AFQm wall-mounted multilevel active filters are designed to address power quality issues in three-phase industrial, commercial, and service installations by actively reducing harmonic distortion and compensating reactive power. Compact and easy to install, these filters support both three- and four-wire systems, operate across multiple voltage ranges and 50/60 Hz networks, and mitigate harmonic currents up to the 50th order.
They also provide power factor correction for both inductive and capacitive loads, along with phase current balancing and neutral current improvement in four-wire configurations. For applications with higher demands, multiple AFQm units can be connected in parallel to increase overall filtering capacity.
