Verdict: pick a centrifugal blower if you want the highest stated airflow: the XPOWER P-230AT lists 925 CFM with ETL/CETL certification and a 1-year limited warranty. Pick an inline fan if you want a duct-ready fan built for laser engravers: both Makacces listings name laser engravers and include a pipe or hose, at a stated 30dB. The blowers are marketed for drying and ventilation, not laser exhaust specifically.

Centrifugal blower vs inline fan for laser: the key differences
The split is simple: the two centrifugal blowers move air with no duct stated, while the two inline fans are built for ducts with a pipe or hose in the box. Below is how that split plays out across airflow, noise, mounting, power and warranty.
Airflow: CFM against cubic meters
The blowers state airflow in CFM: 925 for the P-230AT and 600 for the P-80. The inline fans state 200 cubic meters per hour, a different unit, so the listings do not invite a direct comparison. The second Makacces listing muddies its own figure, with 200 CFM in the title against 200 cubic meters per hour in the bullets.
Noise
The inline fans both state 30dB. The P-230AT states 45 dB. The P-80 states no noise figure. On the stated figures, the inline fans are the lower-noise side of this comparison.
Mounting and ducts
The inline fans are built for ducts: the first includes a 1.5M pipe and mounting screws, the second a 2M exhaust hose per its title (its bullets say 1.5M pipe), and both name laser engravers as a use. The blowers are floor-standing air movers with no duct connection stated. If the laser needs a hose to the window, the inline fans are the duct-ready side.
Power and safety
The P-230AT draws 150 watts and the P-80 138 watts; the inline fans list 50 watts and 25 watts in their spec tables, though the second fan’s title says 35W. Only the P-230AT is ETL/CETL safety certified with dual thermal protection; the P-80 lists ETL in its spec table. Neither inline fan states a certification. Only the P-230AT states a warranty, a 1-year limited warranty.
Choose a centrifugal blower if
- You want the highest stated airflow: 925 CFM on the P-230AT, 600 CFM on the P-80.
- You want a safety-certified blower: ETL/CETL on the P-230AT, ETL in the P-80 spec table.
- You want a stated warranty: 1-year limited on the P-230AT.
Choose an inline fan if
- You want a duct-ready fan: 1.5M pipe or 2M hose included.
- You want a fan built for laser engravers, named in both listings.
- You want the stated 30dB low noise.
