Description
Bosch Aerotwin AR644S – wiper blade, 700 mm long, developed using a frameless assembly.
Built for every season, the AR644S windshield wiper resists harsh weather and road salt to keep your view perfectly clear.
Bosch AR644S model incorporates an high-performance asymmetric fin, designed to deliver 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 minimal noise and vibration even in turbulent weather.
Ideal for highway commuters, this spoiler enhances stability for a smoother drive.
Frameless replacement blade delivers a streamlined flat spine, purpose-built to hold pinpoint wiping accuracy across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, producing a silent, streak-free sweep. Its low-drag aero spoiler reduces drag, while slide-in multi-adapter suits most makes and models for hassle-free fitting. 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.
Series Bosch Aerotwin – the top line from the respected German automotive supplier Bosch. Windshield wipers of this range boast an modern frameless construction and are supplied to the production lines of many leading vehicle makers. The wiping element is made from a high-tech composite rubber, offering better performance than natural rubber. Spring strips are produced from a special “Evodium” alloy and maintain their original tension throughout the blade’s service life.
