The Furutech Flow-28 NCF is a high-end inline power filter with NCF technology, α-OCC conductors and EMI/RFI filtering for a cleaner power supply to your hi-fi or AV system. Read more.
The Furutech Flow-28 NCF Inline Power Filter is designed for demanding music lovers and home cinema enthusiasts who consider power delivery an integral part of a high-performance audio system. This compact high-end mains filter fits between an existing power cable and an audio component or power distributor, helping to reduce unwanted high-frequency EMI and RFI interference.
Combining Furutech's NCF technology, high-quality α-OCC copper conductors, GC-303 EMI-absorbing material and an integrated AC-1501R filter section, the Flow-28 NCF is considerably more sophisticated than a simple mains adapter.
Every amplifier, DAC, streamer, disc player, phono stage and other audio component ultimately depends on mains power. High-frequency interference can be present on the AC supply, while digital electronics and switching power supplies can also introduce electromagnetic and radio-frequency interference within a system.
The Furutech Flow-28 NCF has been engineered to reduce this unwanted noise before it reaches connected equipment. Depending on the system and electrical environment, cleaner power can contribute to a quieter perceived background and make low-level musical information easier to appreciate.
At the heart of the Flow-28 NCF is Furutech's NCF technology. Its construction incorporates nano-ceramic particles and carbon material in a nylon and fibreglass structure designed with both electrical and mechanical damping in mind.
Furutech also uses high-quality α-OCC conductors, specialised insulation, extensive shielding and a vibration-damping outer construction.
The integrated Furutech AC-1501R uses a parallel filtering circuit incorporating a coil and capacitor. Furutech specifies noise reduction of approximately 10 dB at 1 MHz and more than 30 dB at 10 MHz.
The filter is specifically engineered for premium audio applications, where effective high-frequency noise reduction and the preservation of a natural, dynamic presentation are both important.
The Flow-28 NCF incorporates high-grade rhodium-plated Furutech connections with Alpha-treated non-magnetic conductors. Furutech's patented Floating Field Damper technology is also used to help minimise unwanted electromagnetic effects around the metal parts of the connector.
One of the main advantages of the Furutech Flow-28 NCF is that an entire power distribution system does not need to be replaced. The unit can simply be installed between a compatible power cable and an audio component or between the power cable and a power distributor.
This makes the Flow-28 NCF suitable for use with high-quality amplifiers, DACs, network streamers, CD and SACD players, phono stages and many other premium hi-fi and AV components.
The Furutech Flow-28 NCF has also received international recognition, earning a Recommended Award from Hi-Fi Choice. The assessment highlighted a lower perceived noise floor, improved clarity, more precise spatial presentation and tighter bass performance.
