Wiper Blade Set Bosch Aerotwin A640S

Description

This 725 and 725 mm Bosch Aerotwin A640S wiper blade set is built with a frameless design.
A640S provides dependable, year-round windshield cleaning, thanks to dual blades that effortlessly combat frost, snow, and rainstorms.

This Bosch A640S set of wipers boasts an advanced asymmetric deflector, optimized for superior visibility in all conditions.
An asymmetric spoiler is strategically positioned to channel airflow into targeted downforce 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 smudge-free visibility even in strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for a smoother drive.

Frameless windshield wiper blade offers a modern tensioned beam, calibrated for pinpoint wiping accuracy across multi-radius glass. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a whisper-quiet glide. Its wind-cheating contour cuts lift at highway speed, while tool-free quick-click mount suits most makes and models 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). Go beam, drive clear – buy today.

Aerotwin – the premium line from the trusted German manufacturer Bosch. Windshield wipers of this range offer an advanced frameless construction and are supplied to the plants of many European vehicle makers. The wiping element is made from a multi-compound rubber, outperforming natural rubber in key properties. Spring rails are produced from a special “Evodium” alloy and preserve their original tension throughout the blade’s service life.
