Description
The Bosch Aerotwin A640S comes as a frameless construction set of wipers with 725 and 725 mm blades.
Bosch Aerotwin A640S – an all-weather set of wipers built to handle rain, sleet, snow, and high temperatures with consistent, durable performance.
The Bosch Aerotwin A640S wiper blade set features an asymmetric-style spoiler, engineered for unmatched clarity in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during highway speeds. The result is minimal noise and vibration even in strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for dependable performance.
Frameless wiper blade offers a streamlined flat spine, precision-engineered to maintain pinpoint wiping accuracy across multi-radius glass. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a crystal-clear pass. Its wind-cheating contour boosts high-speed stability, while smart-fit mounting heads 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 – elevate now.
Bosch Aerotwin – the top line from the respected European automotive supplier Bosch. Wiper blades in this line boast an modern frameless construction and are supplied to the production lines of numerous European vehicle makers. The wiping element is made from a multi-compound rubber, offering better performance than natural rubber. Spring rails are produced from a special “Evodium” spring steel and preserve their original tension throughout the blade’s service life.
