Description
Bosch Aerotwin A640S – frameless set of wipers, 725 mm and 725 mm for clear visibility.
A640S delivers universal, round-the-year durability—dual blades clearing away sleet, blizzard conditions, and road debris for a spotless windshield on every drive.
The Bosch A640S wiper blade set integrates an asymmetric spoiler, designed to deliver exceptional wipe quality in diverse weather.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during rapid commutes. The result is a crystal-clear visibility even in strong crosswinds.
Tailored for windy climates, this spoiler boosts wipe efficiency for dependable performance.
Frameless wiper blade unleashes a sleek beam profile, purpose-built to hold constant glass contact across complex windshield curves. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a whisper-quiet glide. Its low-drag aero spoiler reduces drag, while slide-in multi-adapter suits 95% of vehicles for rapid installation. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Experience silent clarity – upgrade now.
