OnFILTER is a young California company dedicated to reducing electrical noise in manufacturing, medical and many other environments. Electromagnetic interference (EMI) on power lines and ground creates serious problems for operation of equipment and can even damage sensitive components.

Real-life installations share power lines among many types of equipment, not all of them noise-free. Simple turning on and off one tool can cause severe high-frequency spikes throughout the facility. Such common items as light dimmers, solenoids, stepper motors, controlled heater elements and others greatly contribute to the noise on power lines and ground.

OnFILTER has designed a line of filters specially suited to reduce noise in real-life environment.

Electromagnetic interference (EMI) on power lines and ground creates serious problems for operation of equipment and can even damage sensitive components.

The main focus of OnFILTER is design and manufacturing of filters for reducing noise on power lines and ground for real-life installations. Sensitive equipment shares power lines and ground with many types of machinery and tools, not all of them noise-free. Simple turning on and off one tool can cause severe high-frequency spikes throughout the facility. Such common items as light dimmers, solenoids, servo and variable frequency motors, controlled heater elements and others greatly contribute to noise on power lines and ground.

OnFILTER has designed a line of filters specially suited to reduce noise in real-life environment. Filters already present in electronic equipment are designed to bring the noise from this equipment in compliance with EMC regulations in laboratory environment. Real-life installations offer very different environment where even the most EMC compliant equipment can be a source of high-level noise or fall a victim to its noisy neighbors.

OnFILTER is based in Santa Cruz, California, a wonderful place to live and to raise a family.

We work with the customers around the globe and around the clock
