What is the P-Laser QFC-300 best suited to clean?

The QFC-300 pushes 300 W into a wheeled, air-cooled case — the throughput ceiling of P-Laser's chillerless Compact line, cold-starting in ten seconds for mould and weld cleaning where a trolley-bound water-cooled system cannot go. Typical applications include in-situ mould cleaning, weld-seam oxide removal, on-site maintenance depainting, and hard-to-reach field rust removal.

How does the P-Laser QFC-300 differ from other P-Laser laser cleaning machines?

P-Laser QFC-300: Unlike the water-cooled 500-3000 W QF systems that trade mobility for 50-100 mJ pulse energy, the QFC-300 tops the air-cooled Compact family: the same 1 mJ portable class as the QFC-50/100/200 but the highest average power that still runs chillerless on its own wheels.

What is the pulse width of the P-Laser QFC-300?

The P-Laser QFC-300 has a pulse width of 100 ns (fixed). This is a Standard Q-Switched architecture laser cleaning system.

What is the average power of the P-Laser QFC-300?

The P-Laser QFC-300 delivers 300 W average power at 1064 nm. It uses air cooling.

What pulse repetition rate does the P-Laser QFC-300 support?

The P-Laser QFC-300 supports pulse repetition rates from 20 to 200 kHz.

What laser architecture does the P-Laser QFC-300 use?

The P-Laser QFC-300 uses a Standard Q-Switched architecture operating at 1064 nm (Q-switched nanosecond pulsed fiber).

P-Laser QFC-300 Laser Cleaning Parameters

Rated for the shop floor a chiller cannot follow, the QFC-300 tops P-Laser's air-cooled Compact line without a water loop or a trolley. It carries 300 W of Q-switched nanosecond pulses on wheels, cold-starting in ten seconds for in-situ mould and weld-seam cleaning. Against the QFC-50 through 200, it holds the same 1 mJ portable class while lifting throughput to the family ceiling.
