Best Upgrade for Laser Engravers: How to Change Your Inline Fan

OMTech Laser Updated On Oct 28, 2024

If you're an OMTech laser engraver owner looking to optimize your machine's performance, upgrading the inline exhaust fan is one of the most impactful improvements you can make. A more powerful inline fan significantly enhances the exhaust capabilities of your laser engraver, providing numerous benefits that can elevate your engraving and cutting experience.

Why Upgrade Your Inline Fan?

The stock exhaust fan that comes with OMTech CO2 laser engravers gets the job done, but if you’re consistently performing big-batch jobs, upgrading to a more powerful fan can dramatically improve your machine’s performance. Here's why:

Better smoke and debris removal: A stronger fan more efficiently extracts smoke and small particles generated during laser operations.
Cleaner optics: Improved airflow helps keep mirrors and lenses cleaner, reducing maintenance frequency.
Enhanced cutting performance: Better exhaust can lead to cleaner, more precise cuts.
Reduced odor: A more powerful fan helps minimize lingering smells from laser operations.
Temperature control: Improved airflow can help maintain optimal operating temperatures.

Step-by-Step Guide to Upgrading Your Inline Fan

Before beginning, ensure you have the following:

New inline fan
Screwdriver
Hose clamps
Ducting (both original and new)

Remember to always unplug your laser engraver before beginning any maintenance or upgrades.

Step 1: Remove the Existing Fan

Locate the exhaust fan on your OMTech laser engraver. Depending on your model, it may be on the back or left side of the machine.
Remove the flange surrounding the fan by unscrewing it. Keep these screws safe, as you'll need them later.
Unscrew the fan from its mounting location.
Carefully trace the fan's wires to their connection point and disconnect them. You can either cut and cap the wires or remove them entirely.
Pull the wires back through the machine and remove the fan completely.

Step 2: Prepare for the New Fan

Determine the best location for your new exhaust setup. Consider where the air will exit the room.
Reinstall the flange you removed earlier. This will serve as the connection point for your new ducting.

Step 3: Install the New Fan

Remove the clamps to access the back wall mounting plate on your new inline fan.
Position the fan where you want it, ensuring it aligns with your planned ducting route.
Secure the fan to the wall or chosen mounting surface.
Reconnect the clamps and attach the controller unit.

Step 4: Connect the Ducting

Use the original ducting to connect from your laser engraver to the new fan inlet.
Attach the new ducting (often provided with the new fan) from the fan outlet to your chosen exhaust point.
Ensure all connections are tight using hose clamps.

Step 5: Final Checks and Setup

Double-check all connections and ensure the fan is securely mounted.
Verify the fan's airflow direction. Most fans have arrows indicating the airflow direction.
If your new fan has a controller, position it in a convenient location on your laser engraver.
Plug in your laser engraver and new fan, then test the system.

Tips for Optimal Performance

Regular Maintenance: Even with an upgraded fan, regular cleaning of your laser engraver's optics and exhaust system is crucial for maintaining peak performance.
Adjust Fan Speed: If your new fan has variable speed settings, experiment to find the optimal speed for different materials and operations.
Proper Ventilation: Ensure your exhaust system vents to a well-ventilated area or directly outside to maintain a safe working environment.
Monitor Performance: Pay attention to how the upgraded fan affects your laser operations. You may notice improvements in cut quality, reduced odor, and cleaner optics.
