What is windshield deflector on a car?
03-03,2025
The windshield deflector (also known as rainwater collection defector, rainwater deflector, or drainage board) on a car is an important component under the front windshield of the car. It is mainly used to collect rainwater, guide rainwater to drainage holes, and prevent rainwater from entering the engine compartment or interior of the car. It serves a decoration purpose as well.
Functions of the windshield deflector on a car:
1. Rainwater diversion: Rainwater is guided to drainage holes through rainwater collection troughs to prevent it from accumulating or seeping into the engine compartment, thus protecting internal circuits and mechanical parts.
2. Improvement of visibility: It reduces residual rainwater on the windshield, lowers fogging risk, and enhances driving safety on rainy days.
3. Decoration function: Some windshield deflectors are designed elegantly and in harmony with vehicle lines, thereby contributing to aesthetic appearance of vehicles.
Recommendations for maintenance and replacement of windshield deflector:
1. Daily maintenance: Leaves and sediments in the rainwater collector should be cleaned regularly to prevent blockage of the drainage holes.
2. Time of replacement: If the windshield reflector cracks or deforms, or if its seal fails, it should be replaced in a timely manner. Original or highly compatible replacement parts should be preferably used.
3. Repair method: Minor damages can be repaired through plastic welding. For severe damages, complete replacement is necessary.
The DPA E70-windshield deflector kit features a brand new design using PP and composite rubber materials, leading to excellent resistance to high and low temperatures. A combined left-middle-right packaging structure is adopted to facilitate replacement in one go, saving much time and effort.

Material: For the DPA windshield deflector kit, the original design using PP and SEBS materials prone to aging, damage and failure has been upgraded to a design using PP and compositive rubber materials. As a result, the product does not deform when exposed to sunlight. Nor does it harden or crack at low temperatures.
Mold: The DPA windshield deflector kit is made with original 1:1 precision molds. Therefore the product fits precisely without curling edges and is easy to install.
