This is a brand-new, unused, unopened, undamaged genuine OEM blower fan with part number 089170109022, exclusively designed for the specific planer model R4331. As a core dust removal component of the planer, it is responsible for generating targeted airflow to quickly suck away wood shavings and dust generated during planing operations, guiding the debris out of the working area to keep the cutting surface clean and improve the planing precision of the tool.

Crafted from high-strength, lightweight engineering plastics, the fan blades are precision-molded to ensure balanced rotation at high speeds, minimizing vibration and noise during long-term operation while resisting impact from flying wood chips. Its accurate structural design perfectly matches the planer's motor housing and dust exhaust channel, ensuring a seamless fit that maximizes air ducting efficiency. The fan requires no modification during installation, making it a direct replacement for worn, bent or damaged original blower fans.

Replacing this component quickly restores the planer's dust removal function, ensuring a tidy working environment and preventing wood dust from accumulating inside the tool, which can cause motor overheating or mechanical jamming. It is an essential maintenance accessory for both DIY woodworking enthusiasts and professional users who pursue high-quality planing results.
