Exhaust System Upgrade – Strongly Recommended for Indoor Use
-
While all laser machines are equipped with stock exhaust fans, these factory-installed units often lack the airflow capacity needed for effective smoke and odor removal—especially when used in indoor environments. For optimal performance and air quality, upgrading to a high-efficiency aftermarket inline fan is highly recommended.
-
-
Why Upgrade?
-
The stock exhaust systems included with IOMTech laser machines vary in quality—but most fall short when it comes to efficient smoke removal:
-
Polar Series: These machines are equipped with a 4" exhaust port and include a 4" inline fan that is generally sufficient for most standard applications. However, some users have found that upgrading to the more powerful 6" inline fan (linked below) offers noticeable improvements in airflow and overall ventilation performance—particularly in enclosed or high-use environments.
-
Maker Series: The internal exhaust fans on Maker Series machines are completely inadequate, failing to provide sufficient airflow for indoor/garage use. In fact, is it recommended that these be removed completely from the machine to avoid obstructing airflow of an upgraded inline fan
-
Pronto Series: The included external inline fan is an improvement over the Maker series, but it still lacks the power and performance of the higher-capacity fans recommended below.
-
Pro Series: While the Pro series models include an external fan, it is loud and bulky, and its design can be intrusive in a workspace.
-
-
In all cases, upgrading to a high-performance aftermarket inline fan like those linked below significantly improves smoke extraction, reduces lingering odors, and creates a cleaner, more efficient, and more enjoyable working environment.

Important: Check Your Exhaust Port Size
-
Before purchasing a fan, confirm the size of your machine's exhaust port:
-
Polar Series: Typicalls uses a 4" exhaust port and comes with a 4" inline fan
-
50W and above: Usually come with a 6" exhaust port
-
130W and above: Typically have two 6" exhaust ports

6-Inch Inline Fan – Most Popular Choice for the 20x28" working area machines
-
My previous setup: I use the AC Infinity 6" fan with my AF2028-60 (60W Red/Black CO2 Laser, 20"x28" bed). It handles ventilation well, though a faint smoke smell may linger briefly after use. I did ultimately end up upgrading to the 8" fan eventually to eliminate any smells.
-
Duct Size: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 402 CFM | Noise: 32 dBA | Dual Ball Bearings

8-Inch Inline Fan – For Larger Beds
-
If you’re using a machine with a larger bed—especially anything bigger than 20"x28"—you may benefit from the increased airflow of the 8" fan.
-
Why choose this: It pulls more air, making it ideal for larger machines or setups requiring more aggressive smoke extraction.
-
Note: Slightly louder than the 6" model (39 dBA vs. 32 dBA).
-
Duct Size: 8” | Dimensions: 8.5 x 11.9 x 9.2 in. | Airflow: 807 CFM | Noise: 39 dBA | Dual Ball Bearing

Installation Considerations
-
Thought should be given to how you plan to exhaust your laser when considering where to place the machine.
-
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.
