If you're using a fan as an exhaust fan in an open space (no resistance), then you should focus on CFM. However, if you're connecting the fan to a laser machine (a space with resistance), what matters more is the suction power for smoke extraction and the airflow speed inside the exhaust duct. The internal environment of a laser machine is relatively enclosed, so the greater the suction power, the better the smoke extraction; the faster the airflow, the quicker the smoke will be expelled. Just like a vacuum cleaner, where the focus is on pressure rather than CFM. The greater the pressure, the more thoroughly it cleans.

A traditional 6-inch duct fan with 410 CFM will lose a lot of airflow because the laser exhaust aperture is only 3 inches, resulting in a loss of overall performance. The IF2 fan is 3 inches, matching the laser machine perfectly, so there's no size mismatch and performance is guaranteed.

All xTool laser models are compatible with this purifier (P2S/P2/F1 Ultra/S1/M1 Ultra/M1/F1/D1 pro/D1). Additionally, it can also be used with laser machines from other brands, but you’ll need to get a custom adapter yourself.

This purifier features a cyclone layer, significantly extending the lifespan of the filter compared to others. As a result, the frequency of replacements is reduced, leading to lower maintenance costs.

CFM is not the key factor for laser duct fans. Common large-blade fans, which have 450 CFM, experience a reduction in airflow when connected to laser machines due to the smaller interface, resulting in effective CFM dropping to one-third (only 108 CFM*).

The IF2 is better adapted for laser machines (100% interface compatibility), ensuring no loss in airflow. Additionally, its highest fan speed provides stronger suction and smoke extraction.

Users who have purchased the P2S machine do not need to buy the xTool SafetyPro™ IF2, as the P2S has upgraded its built-in exhaust system to utilize the same technology as this fan.
