Furutech Flow-C15 -G Series Inline AC Power Filter (each)

Furutech Flow-C15 Eliminates AC Line Distortion Without Current Limiting

Furutech Flow-C15 In-line Power Filter is a compact, high-performance power conditioning solution engineered to eliminate electrical noise without compromising current delivery. Designed specifically for high-resolution AV systems and low-profile electronics, the Flow-C15 enhances overall audio and video clarity by targeting and neutralising contamination present in household AC lines. Its inline construction and slim IEC connector make it particularly suited for tight spaces behind AV racks, 4K/8K televisions, and compact integrated systems.

Flow-C15 Reduces Ground Noise, Voltage Spikes, and EMI Interference

Furutech Flow-C15 power filter is built to combat a range of AC line issues including ground loop noise, high-frequency interference, and voltage inconsistencies. At the heart of this filter is the AC-1501 (G) EMI-filtering IEC inlet, which incorporates a parallel circuit featuring an inline coil and capacitor. This precise configuration attenuates noise by 8dB at 100kHz, 14dB at 500kHz, and more than 30dB at 10MHz, shielding sensitive equipment from both internal and external electrical disturbances.

The unit excels at preserving signal integrity by filtering high-frequency digital noise from network devices, switching power supplies, and neighbouring appliances. Its effectiveness becomes particularly apparent during late-night or weekend listening sessions, when electrical interference from neighbouring units typically subsides, revealing the Flow-C15’s full potential even further.

Flow-C15 Enhances Resolution, Dynamics, and Soundstage Transparency

Furutech’s Flow-C15 Filter transforms the sonic character of connected components by lowering the noise floor and revealing finer microdynamics. When used between power cables and source equipment, or between cables and distribution blocks, the Flow-C15 injects realism into playback by widening stereo imaging, sharpening localisation, and enhancing harmonic textures.

Bass response tightens without bloating, while the midrange gains a richer, more expressive tone. High frequencies extend cleanly without etch or fatigue, giving music and film soundtracks added emotional depth. These improvements are delivered without any current limiting, thanks to Furutech’s Pure Transmission design ethos, ensuring compatibility even with current-hungry devices.

Flow-C15 Uses Gold-Plated Connectors and Vibration-Damping Shell

Furutech’s FI-C15 (G) IEC connector, installed on the Flow-C15, is crafted with 24k gold-plated pure copper conductors and non-magnetic materials to optimise conductivity while minimising eddy current distortion. The connector is housed in a nylon resin shell reinforced with vibration-damping fibres, helping to suppress mechanical noise that can further degrade signal quality.

This advanced materials approach extends to the outer body of the Flow-C15, which integrates nano-ceramic particles and carbon powder within a nylon/fibreglass matrix. This hybrid compound dampens both electrical and mechanical resonance, enhancing the filter's overall noise suppression capabilities and thermal stability under continuous use.

Flow-C15 Delivers Audiophile-Grade Construction with Certified Safety

Furutech Flow-C15 in-line power conditioner is fully compliant with IEC standards and certified under UL, CSA, and PSE regulations. It uses silver-plated Alpha μ-OFC conductors – 37 strands per core – arranged in a high-density geometry to ensure stable, low-impedance transmission. Each conductor is insulated with high-grade polyethylene, reducing capacitance while improving signal linearity across frequencies.

An internal Alpha-conductor braid shield and a carbon-infused PVC inner sheath provide layered protection against radiated and conducted noise. The outer jacket, measuring approximately 12.9mm in diameter, is a RoHS-compliant PVC with a flexible, vibration-isolating profile ideal for system installations where physical stress or limited space might otherwise compromise connection stability.

Flow-C15 Integrates Seamlessly With Compact Audio and Video Components

Furutech Flow-C15 with its slim-profile IEC design fits directly between standard power cables and IEC-equipped gear, including flat-panel TVs, compact stereo amplifiers, digital streamers, phono stages, or network players. Unlike bulky conditioners or power distribution blocks, the Flow-C15 offers an elegant, space-saving alternative that doesn’t demand rearrangement of a carefully configured AV layout.

Whether used as a standalone filter or in combination with Furutech’s reference-level power cables, the Flow-C15 introduces a marked improvement in sonic purity and system responsiveness—especially in high-resolution systems where clarity, transient attack, and low-level detail are paramount.
