Alocs Replacement Blower Fan Blades for Ryobi ONE+ 18V Handheld Blowers — 2-Pack, Reinforced Plastic with Insert Nut

Alocs replacement blower fan blades are a two-piece set engineered to replace Ryobi part numbers 529437003, 529437004 and 529437001 for ONE+ 18V handheld blowers.

This pair of replacement fan blades fits Ryobi ONE+ 18V lithium-ion handheld blowers (models P2108, P21081, P21081VN and P21081VNM) and is made from reinforced plastic with inserted nuts for secure fastening. The kit arrives with two fan blades so you can repair both a single blower and keep a spare on hand. The design mirrors the original mounting pattern and blade geometry to restore airflow performance after a cracked or worn impeller has reduced output.

How do these fan blades match my Ryobi ONE+ blower?

Each Alocs fan blade is molded to align with the same hole pattern and center hub dimensions used on the original Ryobi parts 529437003, 529437004 and 529437001. That makes direct replacement possible without modifying the blower housing. The included insert nut helps the blade remain seated under normal vibration and rotation.

• Direct fit for Ryobi P2108, P21081, P21081VN and P21081VNM
• Compatible with OEM part numbers 529437003/529437004/529437001
• Pre-formed hub and mounting holes match factory placement
• Insert nut included to secure the blade to the shaft

How easy is installation for a DIY repair?

Replacing the fan blade is a straightforward, tool-light procedure for anyone comfortable opening a handheld blower. Typically you remove the housing screws, extract the damaged impeller, fit the new blade over the shaft with the insert nut, and reassemble the case. No special calibration is required beyond ensuring the blade rotates freely inside the housing.

• Remove screws to open blower housing
• Unscrew or pull off the damaged fan blade
• Fit Alocs blade onto shaft, secure with insert nut
• Re-seat housing and tighten screws

What materials and durability can I expect?

These replacement blades are molded from durable, impact-resistant plastic tuned for blower applications; the material resists cracking from routine debris strikes. The insert nut gives a stronger mechanical connection at the center hub so the blade stays aligned during rotation. While the blades are engineered for long service, longevity depends on operating conditions and maintenance.

• High-strength molded plastic construction
• Reinforced center hub with metal insert nut
• Resistant to common debris and light impacts
• Pack of two gives a spare for future repairs

Will this restore blower performance and when should I replace the blade?

Installing an intact Alocs fan blade typically restores normal airflow lost to chipped or cracked impellers, provided there are no other internal issues such as motor damage or clogged air passages. Replace the blade if you notice visible cracks, unbalanced rotation, unusual vibration, or a drop in airflow despite the motor running at full speed.

• Replace when blades are cracked, warped, or missing pieces
• Check for vibration or scraping inside the housing
• Inspect motor and vents if airflow does not return after replacement
• Keep one blade as a spare to minimize downtime

Who is this for: This Alocs 2-pack of blower fan blades is intended for homeowners, landscapers and repair technicians who own a Ryobi ONE+ 18V handheld blower (P2108, P21081 family) and need a direct-fit replacement impeller. It suits DIYers comfortable with basic disassembly and anyone looking to restore or maintain blower performance without buying a full new tool.
