Description
Denso Flat DF-401 – frameless wiper blade set, 700 + 550 mm for full-span coverage.
Built for all-weather performance, the set of wipers DF401 ensures streak-free cleaning across both blades in any weather condition.
This Denso (Japan) DF401 set of wiper blades integrates an asymmetric spoiler, engineered for exceptional wipe quality in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into focused windshield grip while minimizing drag, applying extra pressure to the wind-facing edge so the blade hugs the glass during highway speeds. The result is reduced lift and chatter even in strong crosswinds.
Tailored for windy climates, it boosts wipe efficiency for a smoother drive.
Frameless replacement blade delivers a modern tensioned beam, calibrated for pinpoint wiping accuracy across complex windshield curves. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a crystal-clear pass. Its low-drag aero spoiler cuts lift at highway speed, while tool-free quick-click mount 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). Go beam, drive clear – order today.
