Inline Fan

​

  • I consider this to be a necessary upgrade, especially if the machine will be located inside of the house.

​​

  • All machines come with an exhaust fan. Unfortunately they could use some improvement as the stock fans simply do not move enough air.  Therefore, it is recommended to upgrade to an aftermarket inline fan. The two most commonly used inline fans are below.

​​

  • Please verify the size of your exhaust port before ordering. Machines 50w and above should all have 6" exhaust ports. Machines 130w and above have two 6" exhaust ports

 

  • I personally use the 6" fan for my AF2028-60 - 60W Red/Black CO2 Laser with a 20x28 bed. I do get a very slight smoke smell that goes away quickly after I am done using my laser. This is the most commonly used fan. Link to buy is below.

    • Duct Size: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 402 CFM | Noise: 32 dBA | Dual Ball Bearings

 

  • Larger machines, or in particular, beds larger than 20 x 28 have more area from which to pull the smoke. Some people prefer the larger 8" fan for the larger beds due to the higher amount of air drawn (cfm). It is slightly louder (7dBA) than the 6" inline fan. Link to buy is below.

    • Duct Size: 8” | Dimensions: 8.5 x 11.9 x 9.2 in. | Airflow: 807 CFM | Noise: 39 dBA |  Dual Ball Bearings

Installation Considerations

  1. Thought should be given to how you plan to exhaust your laser when considering where to place the machine.
    ​

  2. It is recommended to place the inline fan as close to the exhaust end (farthest away from laser) as possible. The reason for this is that it is easier for the fan to pull the air than it is to push the air. Also, if there are any leaks in your ductwork you will not be pushing the smoke out of them and into your room, instead you will pull air into them and out of the exhaust end.
