Furutech Flow-08 Performance FI-08 Series Inline AC Power Filter (each)

Furutech Flow-08 Delivers High-Performance Inline EMI Filtering

Furutech Flow-08 Inline EMI Power Filter is a high-performance power line noise suppressor designed to elevate the audio and video quality of sensitive electronic systems. This compact yet powerful in-line AC filter directly addresses and mitigates electromagnetic interference (EMI) and radio frequency interference (RFI) that travel along AC power lines and compromise performance across high-fidelity and home entertainment equipment.

Flow-08 Enhances System Performance Without Current Limitation

Furutech Flow-08 is an inline EMI power filter that operates without restricting current draw—an essential trait for high-demand systems. Built around Furutech’s acclaimed Pure Transmission engineering, the Flow-08 ensures optimal power delivery while suppressing unwanted electrical noise. It filters out distortion from ground noise, voltage sags, switching power supply interference, and high-frequency digital noise, without compromising dynamic headroom or transient response. The result is an impressively silent noise floor with increased clarity, expanded soundstage, and a more refined tonal balance.

This filter is ideally suited for use with MacBook Pro and Air, laptops, NAS units, active desktop speakers, subwoofers, AV amplifiers, Blu-ray players, gaming consoles like PS3, HDTVs, and network audio players. Each component benefits from a cleaner power environment, resulting in improved image stability, lower jitter, and richer sonic detail.

Flow-08 Uses Advanced Conductive Materials for Noise Suppression

Furutech Flow-08 High-Performance Inline EMI Filter uses advanced material science to achieve significant noise suppression across a wide frequency range. The inline AC-1001G EMI-filtering IEC connector includes gold-plated α (Alpha) nonmagnetic copper alloy conductors that prevent the magnetic distortion common in lower-grade metals.

Flow-08 incorporates a parallel coil and capacitor network that targets key EMI frequency ranges, achieving noise reduction of 8 dB at 100 kHz, 14 dB at 500 kHz, and more than 30 dB at 10 MHz. This makes it highly effective against both low- and high-frequency interference, which is especially critical in audio systems relying on digital signal chains and processor-based devices.

The C7 IEC connector fits a wide range of devices, and its 24k gold-plated α (Alpha) contacts ensure consistent, corrosion-resistant connectivity. These proprietary components deliver ultra-low resistance and prevent thermal fatigue, further enhancing long-term performance and durability.

Flow-08 Combines Passive Filtering with Structural Isolation

Furutech Flow-08 EMI Filter uses Furutech’s proprietary GC-303 passive EMI-absorbing compound to suppress noise through absorption rather than impedance, preserving current integrity. The internal metal clamp system, a patent-pending design, enhances cable stability while mechanically isolating vibration-induced distortion. This helps prevent microphonic interference and preserves system coherence at both low and high volumes.

The α (Alpha) conductor shielding, flexible RoHS-compliant PVC outer sheath, and high-grade internal insulation work in tandem to reduce radiated noise and mechanical resonance. The result is improved system stability and a cleaner signal path, particularly when used with sensitive or high-resolution components in complex AV or hi-fi setups.

Whether you're refining a desktop audio setup or cleaning the power feed for a premium AV rig, the Furutech Flow-08 Inline EMI Filter provides a sophisticated, space-saving solution that enhances resolution, tightens bass response, and brings out the full expressive range of your audio and video sources.
