Furutech ASB-2 ion eliminates static from LPs and discs with built-in ionisation
Furutech ASB-2 ion is a high-performance antistatic brush engineered to neutralise electrostatic charge on analogue records, optical discs, and sensitive audiovisual equipment. Developed as part of the Furutech Select Series, the ASB-2 ion integrates a pioneering static removal system that combines mechanical brushing with a built-in ion generator—delivering unmatched performance in audio and video playback environments.
ASB-2 ion neutralises static using dual-action ion emission
ASB-2 ion is the only antistatic brush in its class to feature a built-in ioniser using COREBRID™ TMB fibre, a proprietary composite material developed by Mitsubishi Chemical Corporation. It removes static in two stages: first, through corona discharge from the brush fibres; second, through active ion emission. This process eliminates both pre-existing static and new static fields created during brushing—an issue common to conventional brushes.
With a single press and release of the integrated lever, the ASB-2 ion emits a controlled stream of positive ions followed by negative ions. This eliminates residual surface charge across LPs, CDs, DVDs, Blu-ray discs, projector lenses, and even precision camera optics. The balanced ion flow dramatically reduces noise interference, enabling cleaner signal paths and improved detail resolution in both audio and video formats.
Furutech Select Series brush operates without batteries using piezoelectric energy
Furutech’s ASB-2 ion generates voltage autonomously using a piezoelectric element embedded in its compact body. The energy harvested by pressing the lever powers the ion generator, completely eliminating the need for batteries or external power sources. This battery-free design allows for reliable long-term use and ensures the brush is always ready to neutralise static without downtime or maintenance.
Its compact size and portable design make the ASB-2 ion ideal for both fixed hi-fi setups and mobile AV maintenance applications. Despite its mechanical simplicity, the device achieves the functionality of a dedicated ion generator in a highly accessible form factor.
Antistatic brush features ultra-fine bristles designed for vinyl record grooves
ASB-2 ion incorporates precision-engineered bristles made from COREBRID™ TMB fibre mixed with natural wool, providing the ideal balance of flexibility and body. With fibres measuring only 30 microns in diameter—thinner than a human hair—these bristles reach deep into the grooves of vinyl records to dislodge embedded dust particles without damaging delicate surfaces.
The combination of ultrafine synthetic fibres and natural wool ensures effective dust removal while maintaining the soft contact necessary for safe cleaning. This level of material refinement makes the ASB-2 ion a premium tool for analogue record collectors seeking the highest fidelity playback.
Ionising brush is safe for sensitive optical and electronic components
Furutech ASB-2 ion is safe for use on static-sensitive electronics due to its high-resistance composite fibre structure. The core-sheath construction reduces the risk of accidental discharge or short circuits when cleaning components like camera lenses, projector optics, and exposed circuitry.
The brush’s carefully designed electrical properties, combined with its mechanical efficiency, make it suitable for use across a range of high-precision devices where static can degrade image quality, attract dust, or disrupt signal integrity. Whether applied to vinyl playback, Blu-ray performance, or visual equipment maintenance, the ASB-2 ion ensures professional-grade static elimination with every use.
