Compatibility & Fitment
This fan blade is the primary replacement part for the Ryobi ONE+ 18V compact cordless blower series. Key compatible models include:
- Ryobi 18V ONE+ Models: P2108, P21081, P21081VN, P21081VNM.
- Series Fitment: Designed specifically for the axial/centrifugal hybrid 18V handheld blower platform.
- Note: Not compatible with Ryobi 40V backpack blowers or corded electric models which utilize a larger diameter impeller.
When to Replace
- Excessive Vibration: The blower shakes violently during use, indicating a fin has chipped or the hub has become unbalanced.
- Loud Screeching or Grinding: A high-pitched noise that suggests the fan is rubbing against the internal housing or the metal insert has loosened.
- Loss of Air Pressure: The blower motor runs at full speed, but very little air comes out of the nozzle, often caused by shattered or "rounded" fan blades.
- Visible Hub Cracks: Small stress fractures appearing around the center nut, which can lead to a catastrophic fan failure if not addressed.
- Foreign Object Damage: Large chunks of plastic missing from the vanes after accidentally vacuuming up a stone or thick twig.
Installation Tips
- Safety First: Always remove the 18V battery before attempting to open the blower housing. Even a momentary motor pulse can cause serious injury during fan replacement.
- Reverse Threads Check: Many blower fans use Left-Hand Threads (Clockwise to loosen) to prevent the fan from spinning off during operation. Check your specific model's motor shaft before applying force.
- Housing Cleanup: While the blower is open, use a soft brush or compressed air to remove any accumulated dust or dried grass from the motor vents to prevent overheating.
- Do Not Over-Tighten: Tighten the insert nut firmly but avoid using an impact driver. Excessive torque can crack the plastic hub around the metal insert.
- Manual Spin Test: Before reassembling the outer housing, spin the fan by hand to ensure it clears the internal scroll and isn't wobbling on the shaft.

Cheaper than shoes!
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
Instant hit with a dog that likes chewing shoes! This is a much cheaper alternative than a new pair of shoes. They state it is indestructible but at the same time the directions state when it reaches a certain chewed up point to take it away. So obviously this is destructible but it does allow for a lot of chewing. I can not personally attest to the flavor but it must be good because the dog wanted this chew before i even unwrapped it. It is somewhat ugly in both color and shape but I have had no complaints from the dog! I also appreciate that this can be put in the dishwasher to clean. To be honest i have never considered that with other toys and I do appreciate that it can be placed in the dishwasher. Most importantly, this lasts, the dog is in love with this, there are multiple limbs for the dog to chew. It’s his new favorite toy and worth every bit of the cost!

Durable
Size: Medium & Large, Color: Red Scorpion
This bone has proved to be durable and tasty (per our Labrador). She chews and chews with barely a dent. I’m guessing the flavor is good because it’s still her go-to bone after almost a week. Beware of your pet dropping it on your toes though as it is quite hard.

Durable, Flavorful, Chew Toy
Size: Medium & Large, Color: Red Scorpion
This bacon flavored scorpion shaped dog toy has been a huge hit with my Labrador. The material feels extremely durable and appears to be made from a hard nylon that can stand up to serious chewing.
At first, I was skeptical about the bacon scent because I couldn’t smell anything when I opened the package. The moment my dog started chewing on it, though, the bacon scent became much more noticeable. Anyone else who doesn’t smell it immediately shouldn’t worry because it definitely seems to activate once the toy gets some use.
My dog is an enthusiastic chewer and has not been able to destroy this toy. Even better, I haven’t seen any meaningful signs of wear, gouging, or damage despite repeated chewing sessions. That level of durability is exactly what I was hoping for.
The design also includes areas where treats can be added for extra enrichment, which adds even more value. Most importantly, it has seemed very safe during use, and I haven’t had to worry about pieces breaking off.
Overall, this toy has been durable, engaging, and well worth it. My dog loves it, and I love having a chew toy that can actually survive more than a few days.

Built Tough Enough to Handle Serious Chewers
Size: Medium & Large, Color: Red Scorpion
This toy is noticeably harder and denser than standard dog chew toys, which is the whole point. My dog went after it immediately and the nylon held up through serious chewing sessions without gouging, cracking, or pieces breaking off. For a dog that destroys softer toys in minutes, this actually lasts. Based on a few weeks of use I would expect it to hold up for a month or longer depending on the dog, which is significantly better than most toys in this price range.
The peanut butter groove is the engagement feature that makes a difference. Stuffing it with peanut butter or other spreadable treats keeps a dog interested longer than just chewing on it plain. The scorpion shape (though it resembles a lobster to some eyes) gives multiple parts to chew on, so the dog can rotate between the legs and tail when one section gets boring. That variety helps extend how long the toy stays interesting.
Cleanup is straightforward since it is dishwasher safe, which matters after using peanut butter or other treats in the groove. The teeth cleaning claim is harder to verify in short-term use, but as a durable boredom relief toy for aggressive chewers this performs solidly. It is the kind of toy that actually justifies the price because it does not end up in the trash after a week.

Crawfish that cleans her teeth and tastes like bacon, enough said.
Size: Medium & Large, Color: Red Scorpion, Size: Medium & Large, Color: Red Scorpion
This chew toy is for a medium to large-sized dog and smells like bacon, and who doesn't love bacon? The toy has a heavy-duty safe for dogs nylon core, making it virtually indestructible for aggressive, all-day chewers like my dog. I am from Louisiana, and I love all things crawfish. I thought if she didn't like it, then I could use it to decorate for crawfish parties, but she loves this toy. There is a groove for treats like peanut butter or cheese, whatever your dog is into. My dog likes carrying it around, but I don't think she understands to chew on it yet. However, she must love the bacon taste in her mouth because she hardly takes it out.
I wanted her to chew on it to help clean her teeth; maybe in time, she will start. This toy is dishwasher safe after rinsing it off with soapy warm water. Just place it on the top rack and turn it on. The crawfish is smooth and non-porous, so there are no spots for bacteria to hide. I really like this crawfish, and I hope that in time my little weirdo will understand that it is meant to be chewed, not sucked on. I highly recommend this for larger dogs that love to chew, and I am happy with this order.
