How does the M300 sit against the air-cooled M100 and M200?

The M300 sits above the air-cooled peers as the water-cooled ceiling of the same standard Q-switched class. It holds 300 W average power for longer continuous duty than the M100 and M200 while staying below the higher-energy M500 and M1000 cabinets.

When should a shop pick the M300 instead of the M500 or M1000?

Stay with the M300 when the job still clears by controlled surface cleaning in the standard Q-switched class. Move up only when the line needs the higher-energy cabinets for thicker stacks the M300 class is not meant to detach. The published 300 W water-cooled rating is the ceiling of that standard tier.

What wavelength and power does the JETlaser M300 publish?

Published fleet numbers list 1064 nm wavelength and 300 W average power on a pulsed fiber cleaning system with water cooling. Those two numbers, plus the standard Q-switched architecture, are what buyers compare first against other JETlaser models.

Which jobs fit the M300 in the 4JET line?

Shops use this class for tire-mold work, rubber compression-mold residue, weld-seam bonding prep, and composite pre-bond surfaces that need sustained 300 W cleaning without jumping to a high-energy cabinet. Confirm fit with a coupon map on the real contaminant stack before production.

The 4JET JETlaser M300 is a 300 W, 1064 nm water-cooled pulsed fiber cleaner in the standard Q-switched class. This page gathers fleet numbers, coupon-to-production steps, buyer FAQ, Class 4 facility rules, compare-ready facts, and mis-set failure paths so tire-mold and rubber compression-mold shops can place the unit against air-cooled M100/M200 peers and higher-energy M500/M1000 cabinets without inventing new limits.

Parameter ranges

4JET JETlaser M300 positioned against other 4JET machines. Orange/blue = this model; slate band = 4JET min–max for that property. Missing properties are omitted.

Each row is scaled to the 4JET lineup max for that property (not a shared multi-unit axis). Validate against machine calibration before production use.
