Ryobi Air Cannon Tames Florida Summer Heat
When the Ryobi Air Cannon made its appearance in our shop, I immediately had several ideas of where I wanted to use itโif it had the airflow to match its size. It looks like a small drum fan, but much larger than most of the battery/hybrid offerings from other brands. With temperatures already hovering in the mid-90s, putting the Ryobi P3340 is a breeze.
Pros
- Hybrid power: Ryobi One+ 18V battery or AC
- 2,400 CFM max airflow
- Excellent runtime
- Run quiet enough for indoor use
- 4โฒ AC cord included
Cons
- No major drawbacks
Performance
Airflow
How happy you are with the Ryobi Air Cannon depends on what youโre expecting from it. Comparing it to other battery and hybrid fans from major power tool manufacturers sets the P3340 way ahead for the most part.

The 18โณ drum contains a blade that measures roughly 16โณ and pushes up to 2400 CFM. In this class of cordless jobsite fans, there arenโt any other models weโre aware of with this large a diameter and airflow.

Electric drum fans only get down to around 24โณ and push closer to 3200 CFM. Ryobiโs hybrid model wonโt get you that level of airflow, so youโre looking at performance that sits in between cordless fans and small drum fans.
When Iโm using the fan inside, low speed is plenty of air movement and thereโs good airflow up to 12โฒ away. On high, I get meaningful airflow up to 20โฒ away. Thatโs a pretty solid guide.
ย
Have a 10โฒ x 10โฒ back porch? Go with low while you watch the kids play in the backyard. Have a project youโre working on in the garage? Medium keeps a 16โฒ area cool. Working a jobsite? High can cover an entire room.

Runtime
For runtime testing, I used a 4.0 Ah battery to see how long it runs in all 3 modes.
- Low: 7 hrs, 12 min, 20 sec
- Medium: 2 hrs, 46 min, 7 sec
- High: 1 hr, 45 min, 3 sec
If youโre using Ryobiโs newer 5.0 Ah, 6.0 Ah, or 9.0 Ah batteries, youโll get quite a bit more. If we do a little math, hereโs what those runtime numbers look like with a 9.0 Ah pack:
- Low: ~16 hrs, 15 min
- Medium: ~6 hrs, 15 min
- High: ~4 hrs
Ryobi Air Cannon Hybrid Fan Key Features
Hybrid Power
Use any Ryobi One+ 18V battery, the included 4โฒ extension cord or a longer extension cord for power.


Top Carry Handle
As a larger fan, the Ryobi P3340 weighs more than other cordless options. A top carry handle makes it much easier to move its 14.8 pounds around.
Rotating Head
With 220ยบ of drum rotation (including down angles), you can direct air in any direction by either pivoting the drum or turning the fan.

Mounting Options
When you take the Ryobi Air Cannon with you, itโs going to sit on its frame most of the time. But when you know youโre going to use it in the same place around your house or shop, itโs worth it to drive screws in those places.

The keyhole has an oversize opening that helps you set it easier. With its weight, thatโs a good thing, especially if you want to hang it overhead. Whether youโre hanging it overhead or against a wall, be sure you drive a screw into a stud so it doesnโt rip through your drywall or plaster.
Price
The Ryobi Air Cannon with its 4โฒ AC cord runs $149 at Home Depot. Since no one else has a fan this size, its tough to make a direct comparison. Inexpensive 24โณ drum fans are as low as $90, but decent ones are $129 and up. Cordless and hybrid fans start around $40 and run up to $180 or so.
Realistically, this is a different tool from either type and $149 is a solid price for what you get.
The Bottom Line
The Ryobi Air Cannon started a little executive-level feud in our office that I ultimately won. Donโt tell Clint, but I got him one for Fatherโs Day and hopefully, that will cool things down.
The P3340 moves a ton of air compared to other battery/hybrid options and it has solid runtime numbers, especially if youโre moving up to Ryobiโs higher capacity battery packs. With AC power to back it up when you have access, Ryobi keeps you cool on the porch, in the garage, on the job site, during power outagesโฆeven up in an attic.
